Using the chores.csv file fat the very bottom; write an awk script to return the average number of minutes required to complete a chore. Your solution must handle an undefined number of chores. zero points will be given to solutions that use a static number in their calculation.
Format floating point numbers to 2 decimal places.
Example output;
Average: 28.12

Write a program that prompts the user to input five decimal numbers. The program should then add the five decimal numbers, convert the sum to the nearest integer, and print the result.Use the static_caststatement with an appropriate equation to convert the sum to an integer. Compile and run your program with the following test data:Case 1: Input: 5.1, 5.1, 5.1, 5.1, 5.1. Expected Output: 26.Case 2: Input: 5.0, 5.0, 5.0, 5.0, 5.0. Expected Output: 25

Answer:
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
double num1, num2, num3, num4, num5, sum = 0;
cout << "Input: ";
cin >> num1 >> num2 >> num3 >> num4 >> num5;
sum = num1 + num2 + num3 + num4 + num5;
cout << "Output: " << static_cast<int>(round(sum)) << endl;
return 0;
}
Explanation:
Include cmath to use the round function
Declare the variables
Get the five numbers from the user
Sum them and assign the result to the sum
Round the sum using the round function, and convert the sum to an integer using static_cast statement
Print the sum
Write a script called checkLetter.sh Review Greeting.sh for an example. Use a read statement and ask user to "Enter A, B, or C: "
If user types A, echo "You entered A"
If user types B, echo " You entered B"
If user types C, echo " You entered C"
Use the case structure to test the user’s string.
If user types any letter from lower case ‘a through z’ or upper case ‘D through Z’, echo "You did not enter A, B, or C".
