Looping Statements in C

Looping statements are used to execute a block of code repeatedly, either for a specific number of times or until a condition is met.

• A loop continues to execute as long as its condition remains true.
• Loops help in situations where repetitive tasks are required.

Types of Looping Statement in C:

• for loop
• while loop
• do-while loop

1.) for loop

The for loop is used when you know beforehand how many times you want to execute a statement or a block of statements.

Syntax:

for (initialization; condition; increment/decrement) {
    // Code to execute
}

Example:

#include <stdio.h>
int main() {
    int i;

    for (i = 1; i <= 5; i++) {
        printf("Number: %d\n", i);
    }

    return 0;
}

2.) while loop

The while loop is used to execute a block of code as long as the specified condition is true. It checks the condition before executing the loop.

Syntax:

while (condition) {
    // Code to execute
}

Example:

#include <stdio.h>
int main() {
    int count = 1;

    while (count <= 5) {
        printf("Count: %d\n", count);
        count++;
    }

    return 0;
}

3.) do-while Loop:

The do-while loop is similar to the while loop, but it executes the loop body first and then checks the condition. So the loop executes at least once.

Syntax:

do {
    // Code to execute
} while (condition);

Example:

#include <stdio.h>
int main() {
    int i = 1;

    do {
        printf("Value: %d\n", i);
        i++;
    } while (i <= 5);

    return 0;
}
