需要幫助輸出長字符串

Question

當我使用cout很長的字符串時，它不輸出整個字符串，只輸出結尾。

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

輸出：呃---- 248個字符

這是字符串的結束而已，最開始的被切斷

Answer 1

寫輸出到一個文件，並檢查內容是否在文件中。我猜想你的字符串包含回車（'\r'）字符，它們會將輸出的位置移動到行的前面，從視覺上覆蓋已寫在此行上的字符。但是，所有的字符都應該在文件中可見。

Answer 2

我這個測試：

#include <iostream> 

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

這裏是我的輸出：

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

似乎沒有要什麼錯

Answer 3

我用Visual Studio 2010的C++編譯器測試，並且完全按照您所寫的和我的輸出編碼：

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

適合我。
