Next we write the c code to create the infinite loop by using macro with the following example. We use the wrong loop condition which causes the loop to be executed indefinitely. Here is a trick to make for loop as an infinite loop without using any value within the loop statement. As we put the condition (i>=1), which will always be true for every condition, it means that "hello" will be printed infinitely. Hi I learning c++ through a book but I have found that one of the examples provided by the book is an infinite loop. As a result our application is stuck at the infinite loop and cannot continue.

If the break statement is used in the innermost loop. Infinite loops can be implemented using various control flow constructs. step2: If the condition returns true then the statements inside the body of while loop are executed else control comes out of the loop. 4. Use of Logical operators in while loop. To create the infinite loop we can use macro which defines the infinite loop. We know that, generally for loop has three parts initialization of loop counter , conditional statement and increment/decrement (or updating the loop counter ), we can make a for loop infinite without using these three parts . 2.
