🟡 Control Flow · Lesson 17

for Loop in C++

What is for Loop in C++?

for Loop in C++
for loop एक block को तब दोहराता है जब repetitions की संख्या पता हो या counter से control हो।

Level
🟡 Control Flow and Core Programming

Example File
for-loop.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
initialization	for Loop in C++ programming में Initialization use होता है।
condition	for Loop in C++ programming में Condition use होता है।
update	for Loop in C++ programming में Update use होता है।
iteration	for Loop in C++ programming में Iteration use होता है।
counter	for Loop in C++ programming में Counter use होता है।

Syntax / Pattern

C++

for(initialization; condition; update) { statements; }

Example Program

main.cpp

#include <iostream>
using namespace std;
int main(){
    for(int i=1; i<=5; i++){
        cout << i << " ";
    }
    return 0;
}

Expected Output

1 2 3 4 5

Program Explanation

i starts from 1.
Loop runs while i <= 5.
i++ increases counter after each iteration.

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?

tables
patterns
array traversal

Common Mistakes

Creating infinite loops.
Wrong start/end condition.

Practice Tasks

Print table of 7.
Print first 10 natural numbers.

Summary

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