It is not necessary to initialize the counter variable In C

It is not necessary to initialize the counter variable. In C++, it is allowed to define a variable in the initialization expression of the for loop. A While loop\'s body can contain multiple statements, as long as they are enclosed in braces. You may nest while and do-while loops, but you may not nest for loops. A for loop is a post- test loop
