A difficulty about C

Question

When I try to write a simple C program with iPad, but if I use “scanf” statement and then click RUN to run. System always show me Looks like your program has no input. How can I solve this problem.

#include <stdio.h>

int main()
{
int a,b,sum;
printf("Please input a,b:\n");
scanf("%d%d",&a&b);
sum=a+b;
printf("%d",sum);
return 0;
}

These code is only to help me test software. I’m a new learner.

Answer 1

use comma between &a and &b just like this (&a,&b);

Answer 2

can you show us the code?

Answer 3

thanks emmey

Answer 4

show me your source code

Answer 5

No, use comma can’t solve it. Maybe App doesn’t support the function of “scanf()”

Answer 6

Awanish is right. That is the only issue. Other than that the code runs fine. put a , between them in the scanf line.

Answer 7

Oh, yeah! I get it. Thanks Avi Srivastava and Emmey.
