How to concatenate an array of strings into one string and separate them with spaces?

Answer 1

If this is C++ and you are using std::string, then you can stupidly sum the strings through += .
If, according to the condition of the assignment, you need to do everything by hand, then you need to allocate memory so that everything fits, and then you can use strcat_s , memcpy , or even copy character by character.
