Write A C Program To Add two Numbers using pointer
C programming code
#include<stdio.h>
#include<conio.h>
void main()
{
int first, second, *p, *q, sum;
{
int first, second, *p, *q, sum;
printf("Enter two integers to add\n");
scanf("%d%d", &first, &second);
scanf("%d%d", &first, &second);
p = &first;
q = &second;
q = &second;
sum = *p + *q;
printf("Sum of the numbers = %d\n", sum);
getch();
}
}
C program to add numbers using call by reference
#include<stdio.h>
long add(long *, long *);
int main()
{
long first, second, *p, *q, sum;
printf("Input two integers to add\n");
scanf("%ld%ld", &first, &second);
sum = add(&first, &second);
printf("(%ld) + (%ld) = (%ld)\n", first, second, sum);
return 0;
}
int main()
{
long first, second, *p, *q, sum;
printf("Input two integers to add\n");
scanf("%ld%ld", &first, &second);
sum = add(&first, &second);
printf("(%ld) + (%ld) = (%ld)\n", first, second, sum);
return 0;
}
long add(long *x, long *y) {
long sum;
sum = *x + *y;
return sum;
}
long sum;
sum = *x + *y;
return sum;
}
