Copy and Addition (Concatenation) of string class based strings

A demonstration program to see how string objects of string class are copied or concatenated one after the another.

Learning Objectives

  • Learning to copy and concatenation of string objects.

Source Code

TC++ #3028

Source Code

  Related (?) :

Run Output

Welcome to the world of c++

Code Understanding

string s1,s2,s3;
Three string class objects are declared;

s1 instance is assigned a string literal.

The contents of s1 are copied to s2

s3=s2+” to the world of c++”;
contents of s2 are concatenated with another string literal

Final concatenated string is printed


  • While concatenation string class based objects do not need care regarding the size of destination string as for such objects sizes are dynamically allocated by the compiler itself. This is a major advantage of using string class as against c-style null terminated strings.

Suggested Filename(s): stringcl-copy-concat.cpp
