C language: While loop format

While loop format:

while (conditional expression) {

Statement

....

}

Note the point:

Loops: Used to handle a number of repeated operations

Specific steps to write a loop:

1. Identify actions that need to be performed repeatedly

2, determine the conditions of the cycle termination:

1. Before the loop starts, something needs to be done (define a loop control variable and initialize it)

2, determine the cyclic constraint conditions

3, at the end of each cycle or in the loop, to change the value of the loop control variable, so that it constantly close to the constraints
