如何让＆QUOT; I + = X＆QUOT;工作原理＆QUOT;我++ QUOT ;? [英] how to make "i+=x" works as "i++"?

问题描述

以下code

int i=0;
while(i<10) {
   printf("%d\n", i++);
}

等同于

int i=0;
while(i<10) {
   printf("%d\n", i); i++;
}

但下面code

But the following code

int i=0;
while(i<10) {
   printf("%d\n", i+=2);
}

等同于

int i=0;
while(i<10) {
   i+=2; printf("%d\n", i);
}

如何使它相当于

int i=0;
while(i<10) {
   printf("%d\n", i); i+=2;
}

同我++

推荐答案

好奇至于如何努力，我会打的建议那样明显的东西为：

Curious as to how hard I'll be hit for suggesting something as obvious as:

for(int i = 0; i < 10; i += 2) {
    printf("%d\n", i);
}
