将2个字符分配给int [英] Assign 2 char to an int

问题描述

我想了解此代码的结果：

I am trying to understand the outcome of this code:

#include<iostream>

using namespace std;

int main()
{
    int a = 'dd';
    cout << a;
    return 0;
}

结果是25700.编译器如何获得这个数字？
感谢

The result is 25700. How the compiler get this number? Thanks

推荐答案

'd'的ascii代码是0x64。 'dd'由编译器表示为0x6464，用十进制表示法时为25700.

The ascii code for 'd' is 0x64. The literal 'dd' was represented as 0x6464 by your compiler, which is 25700 when written in decimal notation.
