Question

对于我的节目，我有一个高分的部分。我用字符串获取输入，但是我现在如何使字符串等于char数组呢？仅供参考：字符串playersName已经填写了名称。这是我的代码：

class Highscore
{
    public:
        char name[10];
        ...[Code]...
}

...[Code]...
// Declare variables *The playersName will be filled out already*
string playersName = "";
...[Code]...

// How can I get the data[playerScore].name equal my playersName string?
cin.get (data[playerScore].name, 9);
// I know cin.get will be not in the code since I already get the players name with the string

Answer 1

您可以使用std::string::copy成员函数，例如

// length of the destination buffer so we won't overflow
size_t length = sizeof data[playerScore].name; 

// copy the string content to the char buffer
playersName.copy(data[playerScore].name, length);

// add the `'\0'` at the end
data[playerScore].name[length] = '\0';

Answer 2

你需要

strcpy(data[playerScore].name, playersName.c_str());

C ++使Char数组具有字符串的值
