Currently, each time you want to perform a division, you have to run the program. Fortunately, C++ offers several control structures, similar to the if statement, that repeatedly run the code in a block (this is called a loop). Loops use a bool expression to control whether the repetition should continue. This means that the program can perform its activity many times without stopping.
Any statement that changes the flow of control through the program. Normal control flow is from top to bottom in each function called. An if statement determines whether control flows to the then or else block. A try
