C++ Numbers and Strings
Adding Numbers and Strings
WARNING!
C++ uses the + operator for both addition and concatenation.
Numbers are added. Strings are concatenated.
If you add two numbers, the result will be a number:
If you add two strings, the result will be a string concatenation:
Example
string x = "10";
string y = "20";
string z = x + y; // z will be 1020 (a string)
Try it Yourself »
If you try to add a number to a string, an error occurs:
Example
string x = "10";
int y = 20;
string z = x + y;
