C++基础-assert(断言),static_assert(静态断言)

1.断言(assert)

#include<iostream>
#include<cassert>
using namespace std;
//区别用指针的大小
int divv(int a, int b)
{
    assert(b != 0); //断言
    return a / b;
}

int main1()
{
    cout << divv(1, 0) << endl;

    cin.get();
}

2.静态断言(static_assert)

static_assert(sizeof(void*) == 8, "is not 64, baby");

int main()
{   
//    int b = 0; 
    const int a = 0;
    //static_assert(a > 0,  "is not 64, baby"); //变量不可以使用static_assert
    cin.get();
}
