Strings in C++, The string is a data type used in CPP to store text in the memory. In these slides, we will see how to use String datatype in a c++ program. we will include the string header file, declare string variables, and then do operations on these variables.

3. WHAT IS STRING
• Like int, double, char, and bool, “String” is a datatype.
• Strings are used for storing text (names, sentences, phrases, etc).
• For example:
string name = “Pakistan”;

4. HOW STRING IS USED
A string contains a collection of characters, surrounded by double quotes
Example:
string greeting = "Hello";

5. USING STRING
• To use string, you must include <string> header file in the code
• Example
// Include the string library
#include <string>
// Create a string variable
string greeting = "Hello";

6. SOME STRING EXAMPLES
• String firstName = “John”;
• String lastName = “Doe”;
// Combining two strings in c++:
• String fullName = firstName + lastName;

7. GET STRING FROM USER
#include <iostream>
#include <string>
using namespace std;
int main() {
string fullName;
cout << "Type your full name: ";
getline (cin, fullName);
cout << "Your name is: " << fullName;
return 0;
}

8. C++ STRING LENGTH
To check how many characters are stored in a string, we use length() function of string.
Example:
string alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
cout << "The length of the txt string is: " << alphabet.length();
//OUTPUT of code:
//The length of the txt string is: 26
