🔁 Looping Statements in C

Loops allow repeating code multiple times until a condition is satisfied.

1️⃣ for Loop

📘 Full Definition

The for loop is used when the number of iterations is known in advance. It combines initialization, condition, and increment/decrement in a single line.

⚡ Shortcut: Best for fixed repetitions.

🔹 Syntax:

for(initialization; condition; update) {

   // code to execute

}

#include <stdio.h>

int main() {

    for (int i = 1; i <= 5; i++) {

        printf("%d\n", i);

    }

    return 0;

}

2️⃣ while Loop

📘 Full Definition

The while loop is used when the number of iterations is not known in advance. It keeps executing as long as the condition is true.

⚡ Shortcut: Repeat while condition is true.

🔹 Syntax:

while(condition) {

   // code to execute

}

#include <stdio.h>

int main() {

    int i = 1;

    while (i <= 5) {

        printf("%d\n", i);

        i++;

    }

    return 0;

}

3️⃣ do-while Loop

📘 Full Definition

The do-while loop executes the block at least once, and then continues as long as the condition is true.

⚡ Shortcut: Executes at least once.

🔹 Syntax:

do {

   // code to execute

} while(condition);

#include <stdio.h>

int main() {

    int i = 1;

    do {

        printf("%d\n", i);

        i++;

    } while (i <= 5);

    return 0;

}
