#include <stdio.h>

int main()

{

? ? int a,b,c,d,result;

? ? double result1,result2;

? ? a = 1;

? ? b = 2;

? ? c = 3;

? ? d = 4;

? ? result = a + b - c * d;? ? //在這里體驗(yàn)哦~

? ? result1 = (b - c) / (a + d);

? ? result2 = d * (a - d) / c;

? ? printf("%d\n", result);

? ? printf("%f\n",result1);

? ? printf("%f\n",result2);

? ??

? ? return 0;

}

為什么我運(yùn)行計(jì)算結(jié)果?result1?是0.000000 ???
