problem code - HS08TEST
why I’m getting a wrong answer error?
#include<stdio.h>
float a,b,c;
int mul(float n);
int main(){
scanf("%f %f",&a,&b);
if(a<=b){
if(mul(a)){
c = b - a - 0.5;
printf("%.2f",c);
}
}
if(!mul(a))
printf("%.2f",b);
if(a>b)
printf("%.2f",b);
}
int mul(float n){
while(n>0.0)
n=n-5.0;
if(n==0.0)
return 1;
else
return 0;
}
