解决编程问题的疑惑1.

Question

#include<stdio.h>
int main()
{
    int foot=0;
    int inch=0;
    int a=170;
    a/=30.48;
    inch=a*12;
    if(inch>12){
        inch-=12;foot++;
    }
    printf("%d %d",foot,inch);
    return 0;
}

为什么这个代码输出的是1 48

Answer 1

foot = (int) (a/30.48);
inch = (int)((a/30.48-foot)*12);
