如何在中的C++程序中将字符和整数附加到字符串

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char的值将被更改，并希望保存vector<string>.

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());
