For Loop In C Language

In C, a for loop is a control flow statement that allows you to repeatedly execute a block of code a specific number of times. The syntax for a for loop is as follows:

Copy code

for (initialization; condition; increment/decrement) {    // code to be executed }

The initialization is an expression that is executed once before the start of the loop, typically used to initialize a loop variable. The condition is a boolean expression that is evaluated before each iteration of the loop. If the condition is true, the code inside the loop is executed, and the process is repeated. If the condition is false, the loop exits and the program execution continues with the next statement after the loop. The increment/decrement is an expression that is executed after each iteration of the loop, typically used to update the loop variable.

For example, the following code uses a for loop to print the numbers from 1 to 10:

Copy code

for (int i = 1; i <= 10; i++) {    printf("%d ", i); }

The loop variable i is initialized to 1, then it's compared with 10 in the while loop, and as long as it's less than or equal to 10 the loop will execute, printing the value of i and then increment it.

For loops are useful when you know how many times you want to repeat a certain block of code, they're also useful when you want to iterate over an array or a list.

It's important to make sure that the initialization, condition, and increment/decrement expressions are
