/* User defined function in c Language */


int addNumbers(int a, int b);         // function prototype

int main()
    int n1,n2,sum;

    printf("Enters two numbers: ");
    scanf("%d %d",&n1,&n2);
    sum = addNumbers(n1, n2);        // function call
    printf("\nsum = %d",sum);

    return 0;

int addNumbers(int a,int b)         // function definition   
    int result;
    result = a+b;
    return result;                  // return statement
