Flowchart of for Loop
Example: Program to Demonstrate How to Use for Loop
C
// C Program to illustrate the use of for loop #include <stdio.h> int main() { // loop variable int i = 0; // for loop that prints "GFG" 5 times for (i = 5; i < 10; i++) { printf("GFG\n"); } return 0; } |
C++
// CPP program to demonstrate // for loop #include <iostream> using namespace std; int main() { // Initialize variable 'i' with a value of 0 int i = 0; // Iterate using a for loop from 5 to 9 (inclusive) for (i = 5; i < 10; i++) { // Print "GFG" on each iteration cout << "GFG\n"; } return 0; } |
Java
// Java program to illustrate the use of for loop import java.io.*; class GFG { public static void main(String[] args) { // loop variable int i = 0; // for loop for (i = 5; i < 10; i++) { System.out.println("GfG"); } } } |
Output
GFG GFG GFG GFG GFG
Looping Infinite Times
C
// C program to demonstrate // infinite for loop #include <stdio.h> int main() { // Infinite loop using a for loop with no condition // specified The absence of a condition means the loop // will continue indefinitely until it is explicitly // interrupted or terminated. for (;;) { printf("GFG\n"); } return 0; } |
C++
// C++ program to demonstrate // infinite for loop #include <iostream> using namespace std; int main() { // Infinite loop using a for loop with no condition // specified The absence of a condition means the loop // will continue indefinitely until it is explicitly // interrupted or terminated. for (;;) { // Print "GFG" on each iteration cout << "GFG\n"; } return 0; } |
Java
// Java program to illustrate the use of for loop import java.io.*; class GFG { public static void main(String[] args) { // infinite for loop for (;;) { System.out.println("GFG!"); } } } |
Output
GFG

Difference between for and while loop in C, C++, Java
In C, C++, and Java, both for loop and while loop is used to repetitively execute a set of statements a specific number of times. However, there are differences in their declaration and control flow. Let’s understand the basic differences between a for loop and a while loop.
