下面是我的代码：

#include <stdio.h>

int main()
{
    int inches = 0; 
    int yards = 0;
    int feet = 0;
    const int inches per foot = 12;
    const int feet_per yard = 3;
    printf("Enter a distance in inches: ");
    scanf ("%d", &inches);
    feet = inches/inches_per_foot;
    yards = feet/feet_per_yard; feet %= feet_per_yard;
    inches %= inches_per_foot;
    printf("That is equivalent to %d yards %d feet and %d inches.\n",      
    printf("or %d centimeters\n", inches*2.54);
}

输入：输入距离（英寸）：10
产量：相当于0码0英尺10英寸，或1717986918厘米。
那么，1717986918是什么？
