需要帮助输出长字符串

Question

当我使用cout很长的字符串时，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：呃---- 248个字符

这是字符串的结束而已，最开始的被切断

Answer 1

写输出到一个文件，并检查内容是否在文件中。我猜想你的字符串包含回车（'\r'）字符，它们会将输出的位置移动到行的前面，从视觉上覆盖已写在此行上的字符。但是，所有的字符都应该在文件中可见。

Answer 2

我这个测试：

#include <iostream> 

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

这里是我的输出：

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

似乎没有要什么错

Answer 3

我用Visual Studio 2010的C++编译器测试，并且完全按照您所写的和我的输出编码：

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

适合我。
