Learn to Code: C++ for Absolute Beginners

Inside the String

Explore the fundamentals of C++ strings by learning to initialize strings, access individual characters, and perform concatenation. Understand string manipulation techniques through practical exercises such as reversing strings, shifting characters, and checking palindromes. This lesson builds foundational skills for handling text data efficiently in C++.

We'll cover the following...

Collection

A collection is a general term used to group multiple values into a single unit. We use collections all the time in the real world―a book is a collection of pages, a train is a collection of train cars, and a wardrobe is a collection of clothes.

String

A string is a collection of characters, mostly treated as a single unit. A string is used to store text values like a name, address, message, etc.

Initializing the string

The following program demonstrates the string initialization:

C++
#include <iostream>
#include <string>
using namespace std;
int main()
{
    string string1 = "The is a string.";
    cout << string1 << endl;
    
    return 0;
}

Note: We have to write #include <string> at line 2 to include a header file string that allows the use of string data type in the program.

In the above code:

  • At line 7,
...
