When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Expression 1 is executed (one time) before the execution of the code block. Expression 2 defines the condition for executing the code block. Expression 3 is executed (every time) after the code block has been executed.

Oct 5, 2018 · Use fgets(): while (fgets(line, sizeof line, stdin)) { // don't need to do anything here } printf("%s", line); You don't need a limit on the number of iterations. At the end of the file, fgets() returns NULL and doesn't modify the buffer, so line will still hold the last line that was read.
