Write a program that calculates and prints the average of several integers. Assume the last value read with scanf is the sentinel 9999. A typical input sequence might be 10 8 11 7 9 9999

Following are the program in C programming language

#include<stdio.h> // header file

int main() // main function  

{

int n1;// variable declaration

int c=0; // variable declaration

float sum=0; // variable declaration

float avg1;

printf("Enter Numbers :\n");

while(1) // iterating the loop

{

scanf("%d",&n1); // Read the value by user

if(n1==9999) // check condition  

break; // break the loop

else

sum=sum+n1; // calculating sum

c++; // increment the value of c

}

avg1=sum/c;

printf("Average= %f",avg1);

return 0;

}

Output:

Enter Numbers:

10  

8  

11

7  

9  

9999

Average= 9.000000
