在C和C++中,exit()和之间有什么区别abort()？我试图在错误后结束我的程序(不是例外).

考虑以下C++程序:

#include <cstdlib> // for exit(3)
#include <string>
#include <iostream>
using namespace std;

void die()
{
    exit(0);
}

int main()
{
    string s("Hello, World!");
    cout << s << endl;
    die();
}

通过valgrind运行这个显示了这个(一些输出为了简洁而修剪):

==1643== HEAP SUMMARY:
==1643==     in use at exit: 26 bytes in 1 blocks
==1643==   total heap usage: 1 allocs, 0 frees, 26 bytes allocated
