Missing Number


This is a companion discussion topic for the original entry at https://toph.co/p/missing-number

#include <stdio.h>

int main() {
	int a,b,c,d,e;
	scanf("%d",&a);
	scanf("%d,%d,%d",&b,&c,&d);
	e=b+c+d;
	printf("%d",a-e);
	return 0;
}

what is my problem

scanf("%d,%d,%d",&b,&c,&d);
         ^  ^ this commas

you have to declare ‘a-e’ in another line

Why do you think so?

you should not use comma between %d.
("%d %d %d",&b,&c,&d); >>this the correct form.

#include <stdio.h>

int main() {
int a,b,c,sum,d;
scanf("%d",&sum);
scanf("%d %d %d",&a,&b,&c);
d=sum-(a+b+c);
printf("%d",d);
return 0;
}

after submitting , it says running 0/6 . what’s this ?

I have solved more than 5 problems … but in my profile still showing 0 problem solved… Whats the problem ?
