Question
Execute a C++ program to calculate the perimeter and area of a rectangle. a. program is attached. b. Add a comment line for your name, jag#, program purpose, and date. This is the only change to be made to the source code. c. upload the cpp program file and a results file. Chapter 2, Exercise #9, page 119 - average test scores a. write a program that prompts the user to enter five test scores and then print the average test score to the screen. (Assume that the test scores are decimal) b. Add a comment line for your name, jag#, program purpose, and date. This is the only change to be made to the source code. c. Sample run #1: Use the following 5 numbers: 10.5 5.5 20.0 10.0 5.5 d. Sample run #2: Use the following 5 numbers: 13.3 0.2 13.5 26.03.5 e. upload the cpp program Me and a results file Grading Criteria CakPerimeter..cpp file CalcPerimeter.results file with correct results CalcPerimeter.comment included with name, jag#, program purpose, date CalcPerimeter program executes without errors AvgTestScores: .cpp file AvgTestScores: results file with correct resorts AvgTestScores: comment included-with name, jag#, program purpose, date AvgTestScores: program executes without errorsExplanation / Answer
1)
function to calculate area:
int area(int a, int b)
{
return a*b;
}
2)
function to calculate perimeter:
int perimeter(int a ,int b)
{
return 2*(a+b);
}
3) average:
#include<iostream>
using namespace std;
int main()
{
int n=5;
int arr[5];
for(int i=0;i<n;i++)
{
cin>>arr[i];
}
float avg=0;
for(int i=0;i<n;i++)
{
avg=avg+arr[i];
}
avg=avg/5;
cout<<avg;
return 0;
}
