একই জিনিস বারংবার ( looping ) করতে হলে কি করতে হবে ?

CLASS 7 - Doing the Same Thing Over and Over

In the previous lessons, you've learned the basics of the C program, several important C functions, standard I/O, and some useful operators. In this lesson you'll learn a very important feature of the C language—looping. Looping, also called iteration, is used in programming to perform the same set of statements over and over until certain specified conditions are met.

Three statements in C are designed for looping:

•     The for statement
•     The while statement
•     The do-while statement

Summary
In this lesson you've learned the following:

•     Looping can be used to perform the same set of statements over and over until specified conditions are met.
•     Looping makes your program concise.
•     There are three statements, for, while, and do-while, that are used for looping
•     in C.
•     There are three expression fields in the for statement. The second field contains the expression used as the specified condition(s).
•     The for statement does not end with a semicolon.
•     The empty for( ; ; ) statement can be used to form an infinite loop.
•     Multiple expressions, separated by commas, can be used in the for statement.
•     There is only one expression field in the while statement, and the expression is used as the specified condition.
•     The while statement does not end with a semicolon.
•     The while (1) statement can create an infinite loop.
•     The do-while statement places its expression at the bottom of the loop.
•     The do-while statement does end with a semicolon.
•     The inner loop must finish first before the outer loop resumes its iteration in nested loops.

In the next lesson you'll learn about more operators used in the C language.
