Loops in c programming

In C programming, loops are used to repeat a block of code multiple times until a specific condition is met. There are three main types of loops in C:

1. For loop: The for loop in C is used to iterate a block of code a fixed number of times. It consists of three parts: initialization, condition, and increment/decrement.

Example:
```c
for(int i = 0; i < 5; i++) {
printf("Hello World\n");
}
```

2. While loop: The while loop in C is used to execute a block of code as long as a specified condition is true. It may not run at all if the condition is false at the outset.

Example:
```c
int i = 0;
while(i < 5) {
printf("Hello World\n");
i++;
}
```

3. Do-While loop: The do-while loop in C is similar to the while loop, but the condition is checked at the end of the loop iteration. This guarantees that the loop body will execute at least once before the condition is checked.

Example:
```c
int i = 0;
do {
printf("Hello World\n");
i++;
} while(i < 5);
```

Loops are essential in programming as they allow for efficient repetition of tasks and make code more readable and concise.
