std::string result = concatenateWithStringStream("Age: ", 30); std::cout << result << std::endl; // Output: Age: 30 return 0; } 4. Using std::sprintf() sprintf() is a function from C that is still used in C++. It’s efficient but requires careful handling due to its use of...

Either x or y can be a string literal or character, but not both. If both are string literal, they will not be concatenated. Example Code #include<iostream> using namespace std; main(){ cout << "Hello " + "World"; } Advertisement - This is a modal window. No compatible source was...

Or just use std::string in C++. Mar 15, 2020 at 1:54am closed account (Ey80oG1T) The code is giving me an error. Did you mean? char* s =newchar[] Mar 15, 2020 at 1:56am Repeater(3046) Pretty unlikely he meant that.
