Solution

Please find the required program along with its output. Please see the comments against each line to understand the step.

#include <stdio.h>

double mean(int *arr, int s){

double sum = 0; //initialize sum to 0
  
for(int i=0; i<s; i++){ //iterate through all the array elements
sum = sum + arr[i]; //get the total sum
}
  
double avg = sum/s; //get the average
  
return avg; //return average
  
}

int main()
{
int arr[6] = {1,4,6,2,7,9}; //delcare and initialize int array
  
double avg = mean(arr,6); //call the mean funtion to get the mean
  
printf(\"Mean = %lf\",avg); //print the mean

return 0;
}

OUTPUT:

Mean = 4.833333
