What is looping in C language

Looping in C language allows you to repeat a set of instructions multiple times, based on a specified condition or a predetermined number of iterations. It is a fundamental concept used to perform repetitive tasks efficiently. C provides three main types of loops:
 
for loop:

The "for" loop is commonly used when you know the exact number of iterations needed. It consists of three parts inside parentheses: initialization, condition, and increment/decrement.
for (initialization; condition; increment/decrement) {
    // Code block to execute repeatedly
}

Example:

#include <stdio.h>
int main() {
    int i;
    for (i = 1; i <= 5; i++) {
        printf("Iteration %d\n", i);
    }
     return 0;
}

Output:
Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5

while loop:

The "while" loop is used when the number of iterations is not known beforehand, and the loop will continue executing as long as the specified condition is true.
while (condition) {
    // Code block to execute repeatedly
}

#include <stdio.h>
int main() {
    int count = 1;
     while (count <= 5) {
        printf("Iteration %d\n", count);
        count++;
    }
     return 0;
}

Output:

Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5

do-while loop:

The "do-while" loop is similar to the "while" loop, but it ensures that the code block is executed at least once before checking the condition.
do {
    // Code block to execute repeatedly
} while (condition);
 
Example:

#include <stdio.h>
int main() {
    int count = 1;
     do {
        printf("Iteration %d\n", count);
        count++;
    } while (count <= 5);
     return 0;
}

Output:
Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5

Looping is a powerful construct that allows programs to perform repetitive tasks, process data collections, and iterate through arrays and other data structures. Care should be taken to ensure that the loop condition eventually becomes false to avoid infinite loops.
