Question

C语言中不同类型数据之间的比较？

double a=22;int i=0,k=18,
i=(a+k)<=(i+k)这个是什么意思？为什么是正确的？

Answer 1

i结果应该为0吧。这几个运算符优先级高到低分别是 () <= =
也就是先计算()，i=(40)<=(18).然后再计算<=，结果是0.然后再赋值i=0.

Answer 2

#include <stdio.h>                                                                      
                                                                                        
int main(void) {                                                                        
    double a=22;                                                                        
    int i=0,k=18;                                                                       
    i = ((a+k) <= (i+k)); 22 + 18 是否小于等于 0 + 18                                                                                                                                                      
    printf("%d\n", i);    输出 0                                                               
    return 0;                                                                           
}
