The initial value of the for loop is performed only once. Else the program exit from the loop. The content must be between 30 and 50000 characters. We can make an infinite loop by leaving its conditional expression empty (this is one of the many possible ways). First, we have initialized a variable 'num' with value 1. The condition will be rechecked and since the condition is true loop will be executed, and it will print two on the screen. If suddenly you program runs in infinite loop, then use ctrl+pause/break. working on problem set 1, and I somehow created some kind of infinite loop. you can stop infinity loop in c if you use turbo c compiler so you can use “ Ctrl ” +” End ”. How you do that depends on the kind of application: For a console application ran run from the terminal, press Ctrl - C to close the program. The loop will not stop unless an external intervention occurs ("pull the plug"). After that loop will be terminated and a statement which is immediately after the loop will be executed. In while loop, if the condition is not true, then the body of a loop will not be executed, not even once. Infinite loops are commonly used in programs that keep running for long periods of time until they are stopped like the web server. After each increment, the value of num will increase by 1, and it will be printed on the screen. A do...while loop in C is similar to the while loop except that the condition is always executed after the body of a loop.
