C++ Assert

Assert：只允許正確的條件式，其他條件式會直接噴錯

#include <iostream>
#include <cassert>
using namespace std;

int main()
{

 int number = 0;
 cin >> number;
 assert(number == 0);
 cin >> number;
 assert(number == 0);

 system("pause");
 return 0;
}

不想讓視窗出現，就在cassert函式庫上面加上

#define NDEBUG
#include <cassert>

#include <iostream>
#define NDEBUG
#include <cassert>
using namespace std;

int main()
{

 int number = 0;
 cin >> number;
 assert(number == 0);
 cin >> number;
 assert(number == 0);

 system("pause");
 return 0;
}
