Answer:
The following fix were made to the program
Change void main() to int main(), then set a return value at the end of the main function; e.g. return 0Remove system("pause"); It's not neededFor each of the array, change their lengths to 5 i.e. int votes[5]; string name[5]; and float percent[5];Lastly, calculate the percentage using: percent[i]=((votes[i]*100.0/total))Explanation:
(1) void main implies that the main function will not return any value. So, you change it to int main() and then set the return value
(2) There is no need to pause the program, so system.("pause") is not necessary.
(3) The question says there are 5 candidates. So, we set the arrays to accommodate inputs for 5 values
(4) percent array is declared as float; 100.0 will ensure that it calculates the percentage as a float value.

Explanation:
Which of the following describes an iteration in a computer program?
Answer:
a set of instructions that can be run multiple times throughout a program
Explanation:
A programmer writes 500 lines of computer code in 17 days. Must there have been at least 1 day when the programmer wrote 30 or more lines of code
Answer:
The answer is No
Explanation:
Given data
Total Lines of code= 500
Number of days= 17 days
Number of codes written per day= 500/17
Number of codes written per day= 29.4117
If we multiply 29.4117 by 17
=499.9989
=500 approx
Hence there was never a day when the programmer wrote 30 or more lines
Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.
Answer:
The method in C++ is as follows:
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
double baseArea = calcBaseArea(baseLength, baseWidth);
double volume = baseArea * pyramidHeight;
return volume;
}
Explanation:
This defines the calcPyramidVolume method
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
This calls the calcBaseArea method to calculate the base area of the pyramid
double baseArea = calcBaseArea(baseLength, baseWidth);
This calculates the volume
double volume = baseArea * pyramidHeight;
This returns the volume
return volume;
}

Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: Enter a string: surcharge se Hint - we saw in the lesson how to get the first letter of a string using the substring method. Think how you could use the .length() String method to find the index of the last character, and how you could use this index in the substring method to get the last character.
//import the Scanner class to allow for user input
import java.util.Scanner;
//Begin class definition
public class FirstAndLast{
//Begin the main method
public static void main(String []args){
//****create an object of the Scanner class.
//Call the object 'input' to receive user's input
//from the console.
Scanner input = new Scanner(System.in);
//****create a prompt to tell the user what to do.
System.out.println("Enter the string");
//****receive the user's input
//And store it in a String variable called 'str'
String str = input.next();
//****get and print the first character.
//substring(0, 1) - means get all the characters starting
//from the lower bound (index 0) up to, but not including the upper
//bound(index 1).
//That technically means the first character.
System.out.print(str.substring(0,1));
//****get and print the last character
//1. str.length() will return the number of character in the string 'str'.
//This is also the length of the string
//2. substring(str.length() - 1) - means get all the characters starting
// from index that is one less than the length of the string to the last
// index (since an upper bound is not specified).
// This technically means the last character.
System.out.print(str.substring(str.length()-1));
} // end of main method
} //end of class definition

17.8.1: Writing a recursive math function. Write code to complete raise_to_power(). Note: This example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(), would be more common.
Answer:
The recursion function is as follows:
def raise_to_power(num, power):
if power == 0:
return 1
elif power == 1:
return num
else:
return (num*raise_to_power(num, power-1))
Explanation:
This defines the function
def raise_to_power(num, power):
If power is 0, this returns 1
if power == 0:
return 1
If power is 1, this returns num
elif power == 1:
return num
If otherwise, it calculates the power recursively
else:
return (num*raise_to_power(num, power-1))

% Write a procedure that calculates the sum of the numbers in % a given range. The parameters to this procedure should be % as follows: % % 1. The low end of the range % 2. The high end of the range % 3. The sum of the values in the range % % If the low end equals the high end, then the sum should be % whatever value is equal to the low/high end (the range is % inclusive). If the low end is greater than the high end, % then failure should occur.
Answer:
The procedure in python 3 is as follows:
def add_range(low,high):
if low<= high:
total = 0
for i in range(low,high+1):
total+=i
return total
else:
return "Failure"
Explanation:
This defines the function/procedure
def add_range(low,high):
If low is less or equal to high
if low<= high:
Initialize total to 0
total = 0
Add up numbers in the range
for i in range(low,high+1):
total+=i
Return the total
return total
If low is greater, then return failure
else:
return "Failure"

what would be the result of running these two lines of code
Ski
Surf
Jog
Hike
Answer:
Jog
Explanation:
The variable options is a list containing 5 string values
options = ["ski", "surf", "jog", "bike", "hike"]
Indexing in python starts from 0 ; hence the index values of the list values are :
0 - ski
1 - surf
2 - jog
3 - bike
4 - hike
The statement ;
print(options[2]) means print the string at index 2 in the list named options
The string at index 2 is jog ;
Hence, the string jog is printed.

how do computers help us with our homework
xD I don't know if you said this as a joke, or if you're serious, but here:
A computer can be a helpful tool to complete your homework by giving you access to countless sources of information, it can also provide you with educational games which can enhance a child's learning ability by presenting learning as something fun and interactive as opposed to boring loads of repeated work which barely stimulate learning at all. But keep in mind that a computer can also take the opposite effect on a child's brain, and can gradually turn into addiction.

Advancements in technology often make computer
hardware and software more convenient to use as
well as able to fit a variety of budgets. As
technology advances, it usually gets
smaller and less expensive.
larger and more expensive.
Answer: smaller and less expensive.
Explanation:
As technology advances, the architects of the devices that we use are getting more efficient in the production of said devices such that they are using better materials and techniques in production.
This has led to a situation where devices are increasingly getting smaller in size and cheaper to afford as well. For instance, compare the computers of today to those of the 90's. We have laptops now which are really slim and cost a fraction of what the bulky computers of those days cost.
write a program to display your name, age and address in c programming
Answer:
The program in C is as follows:
#include <stdio.h>
int main(){
char name[] = "Mr. Royal";
int age = 20;
char address[] = "Lagos, Nigeria";
printf("Your name is %s.\n", name);
printf("You are %d years old\n", age);
printf("Your address is %s.", address);
return 0;
}
Explanation:
This initializes the name
char name[] = "Mr. Royal";
This initializes the age
int age = 20;
This initializes the address
char address[] = "Lagos, Nigeria";
This prints the name
printf("Your name is %s.\n", name);
This prints the age
printf("You are %d years old\n", age);
This prints the address
printf("Your address is %s.", address);

Let L be the set of exactly those strings over the alphabet \Sigma = {a, b, c, g}, that satisfy all of the following properties: the length of the string is equal to 5n+3, for some natural number n greater or equal than 0; all of the first (leftmost) 2n symbols are elements of the set {b, c, g}; all of the last (rightmost) 3n symbols are elements of the set {a, b}; the symbols at position 2n+1, 2n+2, and 2n+3 (from the left, i.e., after the first 2n symbols but before the last 3n symbols) are elements of the set {c, g}; Write a complete formal definition of a context free grammar that generates L. If such a context free grammar does not exist, state that the context free grammar does not exist, and prove it.
Answer:
S -> LSR
S -> M
M -> YYY
Y -> c | g
L -> XX
X -> b | c | g
R -> ZZZ
Z -> a | b
Explanation:
This is a long time ago, but I think this does what you want.
Start symbol S expands to LSR and allows you to grow L and R on either side as much as you want. Ultimately S must be replaced by M. Then you have a pattern like LLLLLMRRRRR.
We can then further break down L into 2 times b, c or g, and similar for M and R.
