需要帮助输出长字符串

Question

当我将cout用于非常长的字符串时，它不输出整个字符串，只输出结尾。

std::string test[] = {"alotof text--sdfsdfsdfsdfsdfsfsdferer----248 characters"};
std::cout << *test << std::endl;

输出：er ---- 248个字符

这只是字符串的结尾，大多数开头被切断了

Answer 1

将输出写入文件并检查内容是否在文件中。我猜你的字符串包含回车符（'\r'）字符，这些字符会导致输出的位置移动到行的前面，从而在视觉上覆盖已写在此行上的字符。但是，所有字符都应该在文件中可见。

Answer 2

我测试了这个：

#include <iostream>

int main(){
    std::string test[] = {"alotof text--sdfsdfsdfsddfasdfsdfasdfadfadfadfadfdfadfadfadfadfadfadfadsfasdfasdfasdfasdfasdfafdasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsafsdffsdfsfsdferer----248 characters"};
    std::cout << test[0].length() << std::endl;
    std::cout << *test << std::endl;
}

这是我的输出：

336
alotof text--    sdfsdfsdfsddfasdfsdfasdfadfadfadfadfadfadfadfadfadfadfadfadsfasdfasdfasdfasdfasdfafdasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsafsdffsdfsfsdferer----248 characters

似乎没有任何问题

Answer 3

我使用Visual Studio 2010 C ++编译器进行了测试，并且编码与您编写的完全一样，我的输出是：

335
alotof text--sdfsdfsdfsddfasdfsdfasdfadfadfadfadfdfadfadfadfadfadfadfadsfasdfasdfasdfasdfa
sdfafdasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfadsfasdf
asdfasdfasdfasdfasdfasdfasdfasdfasdfadsfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfas
dfasdfasdfasdfasdfasdfasdfadsafsdffsdfsfsdferer----248 characters

对我来说很好。
