Strings in C++

What is Strings in C++?

Strings in C++
A string stores a sequence of characters. C++ string class is easier and safer than character arrays for most programs.

Level
🟡 Control Flow and Core Programming

Example File
strings.cpp

Main Focus
Concept + syntax + practical C++ program

Why should you learn this?

It helps you write correct and readable C++ programs.
It is used repeatedly in school practicals, projects and competitive programming.
It builds the base for advanced topics such as OOP, STL and data structures.

Important Terms

Term	Meaning / Use
string	Strings in C++ programming में String use होता है।
getline	Strings in C++ programming में Getline use होता है।
length	Strings in C++ programming में Length use होता है।
concatenation	Strings in C++ programming में Concatenation use होता है।
character	Strings in C++ programming में Character use होता है।

Syntax / Pattern

C++

string name; getline(cin, name);

Example Program

main.cpp

#include <iostream>
#include <string>
using namespace std;
int main(){
    string first = "Code";
    string second = "KaFunda";
    cout << first + second;
    return 0;
}

Expected Output

CodeKaFunda

Program Explanation

+ joins two string objects.
The string header provides string class.

Exam Tip: In C++ practical answers, write the logic first, then the program, then expected output. For theory, always include one suitable example.

Where will you use it?

names
messages
search text
form inputs

Common Mistakes

Using cin when input has spaces.
Forgetting #include <string>.

Practice Tasks

Take full name with getline().
Count characters in a string.

Summary

Strings in C++ एक ज़रूरी C++ topic है। परिभाषा सीखें, syntax समझें, example program चलाएं और फिर practice tasks हल करके concept मज़बूत करें।
