How to make a space character in string?

[Code Apperentice]

What do you mean by "space character"? You can just append " " to a string if you want a whitespace...

[ThanosRoot]

you can just write: std::string space = " " /* Blank space */

if that's what you mean...

[codekiddy]

If you mean inserting a white space then:

string str = "helloworld";
str.insert(str.begin() + 5, ' ');
// str is now "hello world"
