i++问题

第一：

int a = 3

计算a++等于多少。

a经过++运算后会自动+1，所以运算后a的值为4       为什么？

第二：

#include<stdio.h>
int main(){
    int a=3;
    printf("a=%d",a++);
        return 0;
}

算出来的结果是a=3

为什么都是a=3，都是a++

可是最后的结果却是不同的，

求大神交流。

谢谢。

教你个理解方法少年，

printf("a=%d",a++);

你以为你打印的是a的值吗？错，你打印的是（a++）这个整体的值；

执行了a++后，a的确是4，但是你没有打印a，你打印的是a++，而a++这个整体的值是a没有被加1时候的值，所以是3。

当然，想++a，不仅a被加1了，++a这个整体的值也是a加1后的值。

祝好，且学且珍惜。
