请教一下为什么我这题做的不对

Answer 1

#include <stdio.h>
int main()
{
    int a,b;
    float f;
    scanf("%d %d",&a,&b);
    if(a <= b)
        printf("OK");
    else 
    {
        f = 1.0*(a-b)/b;
        if( f < 0.1  )
            printf("OK");//超速不超过10%时显示什么？
        else if(f >= 0.1 && f < 0.5)
            printf("Exceed %d%%.Ticket 200",f*100);
        else
            printf("Exceed %d%%. License Revoked",f*100);
    }
    return 0;
}
