C/C++逻辑运算的验证原则

基本原则为：从左向右，当前逻辑表达式不满足立刻停止后续验证

code

// test.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"#include <stdlib.h>int main(void){int m=0;int n=0;if(m==1 && ++n==1){printf("It is OK!\n");}printf("The first n=%d\n",n);if(++n==1 && m==1){printf("It is in!\n");}printf("The second n=%d\n",n);system("pause");return 0;}
