Answer:
ok
Explanation:
For which of the following tasks would a for-each loop be appropriate?
A. Reversing the order of the elements in an array.
B. Printing all the elements at even indices of an array.
C. Printing every element in an array.
D. Determining how many elements in an array of doubles are positive.
E. Determining whether an array of Strings is arranged in alphabetical order.
F. Printing every even number in an array of ints.
Answer:
The answer is "Option B, C, and F".
Explanation:
In the For-each loop, it is used for traversing items in a sequence is the control flow expression. It typically required a loop becomes referred to it as an enhanced loop for iterating its array as well as the collection elements. This loop is a version shortcut that skips the need for the hasNext() method to get iterator and the loop and over an iterator, and the incorrect choice can be determined as follows:
In choice A, it is wrong because it can't reverse the array element.In choice D, it is wrong because it can't determine the array of positive.In choice E, it is wrong because it can't determine an array of the sting in alphabetical order.Why is sequencing important?
A. It allows the programmer to test the code.
B. It allows the user to understand the code.
C. It ensures the program works correctly.
D. It makes sure the code is easy to understand.
Answer:
c i think but if not go with d
Answer:
C
Explanation:
It ensures the program works correctly

Suppose that an intermixed sequence of push and pop operations are performed on a LIFO stack. The pushes push the numbers 0 through 9 in order; the pops print out the return value. For example"push(0); pop(); push(1)" and "push(0); push(1); pop()" are possible, but "push(1); push(0); pop()" is not possible, because 1 and 0 are out of order. Which of the following output sequence(s) could occur? Select all that are possible.
a) 12543 609 8 7 0
b) 01564 37928
c) 6543210789
d) 02416 75983
e) 46 8 75 32 901
Answer:
b) 01564 37928
e) 26 8 75 32 901
Explanation:
Pushes and pulls are the computer operations which enable the user to perform numerical tasks. The input commands are interpreted by the computer software and these tasks are converted into numeric values to generate output.

Question 4 (5 points)
The more RAM you have, the less things your computer can do at the same time.
True
False

As you will solve more complex problems, you will find that searching for values in arrays becomes a crucial operation. In this part of the lab, you will input an array from the user, along with a value to search for. Your job is to write a C++ program that will look for the value, using the linear (sequential) search algorithm. In addition, you should show how many steps it took to find (or not find) the value, and indicate whether this was a best or worst case scenario (... remember the lecture). You may refer to the pseudo-code in the lecture, but remember that the details of the output and error conditions are not specified there. Also, note that in pseudo-code arrays are sometimes defined with indices 1 to N, whereas in C++ the indexes span from 0 to N-1.
The program will work as follows. First, you should ask the user to enter the size of the array, by outputting:
"Enter the size of the array: "
to the console. If the user enters an incorrect size, you should output the error message:
"ERROR: you entered an incorrect value for the array size!"
and exit the program. If the input is a valid size for the array, ask the user to enter the data, by outputting
"Enter the numbers in the array, separated by a space, and press enter: "
Let the user enter the numbers of the array and store them into a C++ array. Up to now, this should be exactly the same code as Lab#2. Next, ask the user a value v to search for in the array (called the "key"), by outputting:
"Enter a number to search for in the array: " to the screen, and read the key v.
Search for v by using the linear search algorithm. If your program finds the key, you should output:
"Found value v at index i, which took x checks. "
where i is the index of the array where v is found, and x is the number of search operations taken place.
If you doesn't find the key, then output: "
The value v was not found in the array!"
Then indicate whether you happened to run into a best or worst case scenario. In case you did, output: "
We ran into the best case scenario!" or "We ran into the worst case scenario!"
otherwise, don't output anything.
Answer:
#include<iostream>
using namespace std;
int main() {
cout<<"Enter The Size Of Array: ";
int size;
bool isBestCase=false;
cin>>size;
if(size<=0){
cout<<"Error: You entered an incorrect value of the array size!"<<endl;
return(0);
}
int array[size], key;
cout<<"Enter the numbers in the array, separated by a space, and press enter:";
// Taking Input In Array
for(int j=0;j<size;j++){
cin>>array[j];
}
//Your Entered Array Is
for(int a=0;a<size;a++){
cout<<"array[ "<<a<<" ] = ";
cout<<array[a]<<endl;
}
cout<<"Enter a number to search for in the array:";
cin>>key;
for(i=0;i<size;i++){
if(key==array[i]){
if(i==0){
isBestCase=true; // best case scenario when key found in 1st iteration
break;
}
}
}
if(i != size){
cout<<"Found value "<<key<<" at index "<<i<<", which took " <<++i<<" checks."<<endl;
} else{
cout<<"The value "<<key<<" was not found in array!"<<endl;
cout<<"We ran into the worst-case scenario!"; // worst-case scenario when key not found
}
if(isBestCase){
cout<<"We ran into the best case scenario!";
}
return 0;
}
Explanation:
The C++ source dynamically generates an array by prompting the user for the size of the array and fills the array with inputs from the user. A search term is used to determine the best and worst-case scenario of the created array and the index and search time is displayed.

write an algorithm and draw a flowchart to calculate the sum of of the first 10 natural numbers starting from 1
Answer:
#include <stdio.h>
void main()
{
int j, sum = 0;
printf("The first 10 natural number is :\n");
for (j = 1; j <= 10; j++)
{
sum = sum + j;
printf("%d ",j);
}
printf("\nThe Sum is : %d\n", sum);
}
Within a loop
Step 1: Initialize a variable to 1 (say x=1)
Step 2: Specifiy the condition
In this case x<=10
Step 3: Increment the variable by 1
using increment operator x++
OR
simply x+=1(x=x+1)
Step 4: Print the value of variable
Terminate the loop
Explanation:
#include
main()
{
int i, n=10, rem, inc=0;
scanf("%d",&n);
for(i=1; i =3)
inc++;
else;
inc--;
}
printf("Final Value=\n",inc);
