For loop Syntax in C/C++
Syntax:
for (initialization; condition; update) {
// Code block to be executed repeatedly as long as the condition is true
}
Explanation of the Syntax:
- In C and C++, the
for
loop is initialized with an initial condition, followed by a loop condition, and an increment or decrement operation. - The loop first executes the initialization part, typically used to initialize loop control variables.
- It then evaluates the condition specified in the loop header.
- If the condition is true, the code block within the curly braces
{}
is executed. - After executing the code block, the loop performs the increment or decrement operation.
- The loop then returns to the loop header and re-evaluates the condition. If the condition remains true, the process continues; otherwise, the loop terminates.
Implementation of For loop Syntax in C/C++:
C++
#include <iostream> using namespace std; int main() { // For loop for ( int i = 0; i < 10; i++) { cout << i << " " ; } return 0; } |
C
#include <stdio.h> int main() { // For loop for ( int i = 0; i < 10; i++) { printf ( "%d " , i); } return 0; } |

For loop Syntax
For loop is a control flow statement in programming that allows you to execute a block of code repeatedly based on a specified condition. It is commonly used when you know how many times you want to execute a block of code.

The syntax of For loop varies slightly depending on the programming language, but the basic structure is similar across many languages.
for (initialization; condition; update) {
// Code block to be executed repeatedly as long as the condition is true
}
Here’s a general overview of the Syntax of For loop:
- Initialization: This is where you initialize the loop control variable. This variable is typically used to keep track of the current iteration of the loop.
- Condition: This is the condition that is evaluated before each iteration of the loop. If the condition is true, the loop continues; otherwise, it terminates.
- Update: This is where you update the loop control variable. Typically, you increment or decrement the variable to ensure progress toward the loop termination condition.
