Question

please using Repl.it basic C-programing

part1

Write a program that requests 5 integers from the user and stores them in an array. You
may do this with either a for loop OR by getting a string from stdin and using sscanf to store formatted input in each spot in the array.

part2

Add a function to the program, called get_mean that determines the mean, which is the average of the values. The function should be passed the array and the size of the array, but use const so that it cannot be changed, only accessed. It should return a double, which is the calculated mean. The main function will print the value.

//Function prototype:
double get_mean(const int [], int);

Answer 1

//Program:

#include<stdio.h>
double get_mean(const int [], int);            //function prototype
int main()
{
   int a[5];
   printf("Enter 5 integers:\n");                 //requesting for input
   for(int i=0; i<5; i++)                       //loop for getting the input
   {
       scanf("%d",&a[i]);                      //getting the input using array in loop
   }
   double m=get_mean(a,5);                  //function call for mean of the integers
   printf("\nThe mean of the numbers is:%.2f\n",m);        //printing the mean
   return 0;
}
double get_mean(const int a[],int n)               //function definition
{
   double sum=0.0;
   for(int i=0; i<n; i++)
   {
       sum+=a[i];                               //calculating the sum
   }
   double mean = sum/n;                          //calculatig the mean
   return mean;                             //returning the mean
}

//Output:
