help plz

#include

using namespace std;

float bank(int wid, float bal);

int main(void)
{
int wid;
float bal;
cin >> wid >> bal;
float x = bank(wid, bal);
printf("%.2f", x);
return 0;
}

float bank(int wid, float bal)
{
if (wid >= bal)
{
return bal;
}
else
{
if (wid % 5 == 0)
{
return (bal - wid - 0.5);
}

    else if (wid % 5 != 0)
    {
        return bal;
    }
}

}

//this code is running properly and is satisfying all the test cases still when I try to submit it shows the wrong answer. the question is ATM and the Problem Code: HS08TEST

142

You are ignoring one more case.
What happens when the test case is : 100 100 ?
Your code will print YES even though the answer is NO . I hope you get the point.

143

#include <stdio.h>

int main() {
// your code goes here
int i,T;
scanf("%d",&T);
for(i=0;i<T;i++)
{
int N,d,m,sum=0,n;
scanf("%d",&d);
N=d;
n=N+1;
while(n>0)
{

        m=n%10;
        sum=sum+m;  
        n=n/10;
    }
    printf("%d",sum);
}
return 0;

}

please tell me why i get wrong answer… Problem Code:[ICPC16C]

// If the Transaction not SUCCESS.
if(withdraw%5 != 0 || acc_amnt < withdraw)

else:
    print("=")

It is showing wrong answer. Why is it so?
