C LOOPS
You may encounter situations, when a block of code needs to be executed several
number of times. In general, statements are executed sequentially: The first
statement in a function is executed first, followed by the second, and so on.
Programming languages provide various control structures that allow for more
complicated execution paths.
A loop statement allows us to execute a statement or group of statements multiple
times. Given below is the general form of a loop statement in most of the
programming languages −
C programming language provides the following types of loops to handle looping
requirements.
Sr.No. Loop Type & Description
, 1 while loop
Repeats a statement or group of statements while a given condition is
true. It tests the condition before executing the loop body.
2 for loop
Executes a sequence of statements multiple times and abbreviates the
code that manages the loop variable.
3 do...while loop
It is more like a while statement, except that it tests the condition at the
end of the loop body.
4 nested loops
You can use one or more loops inside any other while, for, or do..while
loop.
Loop Control Statements
Loop control statements change execution from its normal sequence. When
execution leaves a scope, all automatic objects that were created in that scope are
destroyed.
C supports the following control statements.
Sr.No. Control Statement & Description
1 break statement
