C program to illustrates the use of the break statement

 
#include<stdio.h>
#include<conio.h>

void main()
{
    int m;
    float x,sum,average;

    printf("This program computes the average of a set of computersn");
    printf("Enter values one after anothern");
    printf("Enter a NEGATIVE number at the endn");

    sum=0;

    for(m=1;m<=1000;++m)
    {
        scanf("%f",&x);

        if(x<0)
            break;
        sum+=x;
    }

    average=sum/(float)(m-1);

    printf("n");
    printf("Number of values=%dn",m-1);
    printf("sum=%fn",sum);
    printf("Average=%fn",average);
}

 
This program computes the average of a set of numbers
Enter values one after another
Enter a NEGATIVE number at the end
21 23 24 22 26 22 -1
Number of values = 6
Sum = 138.000000
Average = 23.000000
