Question

I am learning function in C. I want to sum multiple integers using arguments in function. I managed to write a code for adding two integers, but how if I want to add multiple integers and print the total of them? please guide me. Code which i wrote is;

#include<stdio.h>
#include<conio.h>
int sum(int a, int b, int c);
int main (void){
    int x,y,z;
    clrscr();
    printf("Enter first integer to add.\n");
    scanf("%d",&x);
    printf("Enter second integer to add.\n");
    scanf("%d",&y);
    sum(x, y, z);
    printf("Total = %d.\n",sum(x, y, z));
    getch();
    return 0;
}

int sum (int a, int b, int c){
    c=a+b;
    return c;
}

You can do something like this.

sum = 0;

while (ch == "y")
{
scanf("%d", &a);
sum+=a;
printf("Do you want to continue: ");
scanf("%c\n", &ch);
}

printf("%d", sum);

• The idea is to have a variable sum whose initial value is 0.
• Have a while loop that takes a integer a as input & add it to sum.
• You can mantain a variable ch, which can be used to exit out of the loop. Only if the user enters “y”, the user will be asked for integer again.
