Extended data:

In C language, there are three types of loop statements: for statement, while statement and do While statement. They are described as follows:

for

For is an appropriate circular statement, which well reflects three problems that should be paid attention to in correctly expressing the circular structure:

(1) control variable initialization.

(2) circulation conditions.

(3) Update of loop control variables.

Meanwhile:

While structure loop is a when type loop, which is generally used when the number of loops is unknown. What keeps the loop is a conditional expression. If the condition holds, the loop body will be executed; if the condition does not, the loop will exit.

While statement format is:

While (conditional expression)

Circulating body

Conditional expressions should be judged before each execution of the loop body.
