c++忽略断言

#include <iostream>

#include <cassert>

using namespace std;

int main(int argc, char const* argv[]) {

    int a = 123;

    int b = 123;

    assert(a != b);

    cout << a << b << endl;

    return 0;

}

 

g++ -std=c++11 -DNDEBUG -g /home/qiumc/workspace/cpp/demo/test_base.cpp -o /home/qiumc/workspace/cpp/demo/bin/test_base

必须有-DNDEBUG选项，才可以禁用断言的执行
