C++如何追加炭和整数串

Question

如何追加炭和整数串在C++编程与

例如，

int value_of_int = 100; 
char value_of_char[20] = "HELLO"; 
string result_line; 

result_line << value_of_int; 
result_line << value_of_char; 

vector<string> result_set; 
result_set.push_back(result_line); 

int和炭的值将被改变，并且要保存vector<string>.

Answer 1

您可以使用ostringstream：

int value_of_int = 100; 
char value_of_char[20] = "HELLO"; 
std::ostringstream result_line; // #include <sstream> 

result_line << value_of_int << value_of_char; 

vector<string> result_set; 
result_set.push_back(result_line.str());
