What is the purpose of the tostring function in C++?
There is no built-in toString function in C++, which is typically used to convert other data types into a string. Generally speaking, the toString function converts data types such as numbers, characters, arrays, etc., into string form for output or other processing. In C++, you can use std::to_string to convert numerical types into string form. For example:
int num = 123;
std::string str = std::to_string(num);
Please note that for custom data types, it is necessary to overload the toString function in order to convert that type to a string.
