do-while in C A do-while loop is similar to a while Loop in C, except that a do-while loop is execute at least one time. A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given condition at the end of the block (in while).

In every programming language including C++, loop is a process of repeating a group of statements until a certain condition is satisfied. While loop is an entry controlled loop where the condition is checked at the beginning of the loop. The condition to be

In C++ programming, loop is a process of repeating a group of statements until a certain condition is satisfied. Do-while loop is a variant of while loop where the condition isn’t checked at the top but at the end of the loop, known as exit controlled loop.

The reason is scanf reads directly from the standard input and which blocks and waits for user input after it has processed the line. What you need to do is read the line and process that line in your while loop. I’ve modified your code below. char a; char line[1024
