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

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 | String used in Strings in C++ programming. |
| getline | Getline used in Strings in C++ programming. |
| length | Length used in Strings in C++ programming. |
| concatenation | Concatenation used in Strings in C++ programming. |
| character | Character used in Strings in C++ programming. |
Syntax / Pattern
string name; getline(cin, name);
Example Program
#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++ is an important C++ topic. Learn the definition, understand the syntax, run the example program and then solve the practice tasks to make the concept strong.
