Control statements (or)
Control structures
——————-
C is considered as a structure programming language. One of the reason
for this is having various program control structures.
C process the decision making capability and supports the statements
Known as control statements.
There are 3 types of Control statements supported by C.
1. Conditional control statements.
2. Un-conditional control statements.
3. Loop control statements.
1. Conditional control statements:-
C supports 5 types of conditional control statements.
1. Simple if statement.
2. If-else statement.
3. Nested if statement
4. Else if ladder
5. Switch statement.
1. simple if statement:-
It is a decision making statment and is used to control
flow of execution.
syn:- if(expresion)
{
statments;
}
2.If-else statement :-
It is an extension of simple if statement.
syn:-
if(expression)
{
statements-1;
}
else
{
statements-2;
}
3.Nested if statement:-
Using a if statement within another if statement is known as
Nested if statement.
If series of decisions are involved in a program we use
Nested if.
syn:- 1.
if(expr-1)
{
if(expr-2)
{
if(expr-3)
{
——-
——-
——-
if(expr-n)
{
statements;
}
}
}
syn:-2.
if(expr-1)
{
if(expr-2)
{
statements-1;
}
else
{
statements-2;
}
}
else
{
if(expr-3)
{
statement-3;
}
else
{
statements-4;
}
}
4. Else-if Ladder:-
It is also used for series of decissions are involved.
syn:-
if(exp-1)
{
statements-1;
}
else if(exp-2)
{
statements-2;
}
else if(exp-3)
{
statements-3;
}
—————
—————
—————
else if(exp-n)
{
statements-n;
}
else
{
statements;
}
5.Switch statement:-
It is multiway conditional statement used in C language.In situations
where there is need to pick one alternative in many alternative we have to
use Switch statement.
syn:-
switch(expresion (or) variable)
{
case 1:
statements-1;
break;
case 2:
statements-2;
break;
case 3:
statements-3;
break;
———————–
———————–
———————–
case n:
statements-n;
break;
default:
default statements;
}
break:-
It is an unconditional control statement which is used to terminate
from switch statement.
syn:- break;
NOTE:-
1.In switch statement, it can accept only integral value.
(i.e.., int (or) char)
2.It can not accept string (or) float value.
3.In switch statement , default block is optional.
UNCONDITIONAL CONTROL STATEMENTS
——————————–
1.break:- ( keyword )
It passes control
syn:- break;
The break statement causes control to pass to the statement following
the innermost enclosing while , do , for (or) switch statement.
2.continue:- (keyword)
It passes control.
syn:- continue;
It causes control to pass to the end of the innermost enclosing
while , do (or) for statement at which point the loop continuation
condition is re-evaluated.
3.goto:- (key word)
The ‘goto’ statement is an unconditional control statement which is
used up the execution of program sequence by transfer of control to
the some other part of the program.
syn:- goto label;
Where label is ‘C’ valid identifier and is used to the destination
such that the control could transferred.
syn:- identifier:
LOOP CONTROL STATEMENTS
———————–
Loop:-
The process of repeated execution of a block of statements is called
loop.
C supports 3 types of looping statements.They are
1. While loop
2. Do-while loop
3. for loop
Any loop has 3 things.They are
1. Initialize the index
2. Test condition
3. Update the index
1. While loop:-
It is a conditional control loop statement in C language.
syn:-
while(test condition)
{
statements;
}
First thet test condition is evaluated and if it is true then
the statements block will be executed.After the execution of statements the
test condition is evaluated once again. Then if it is true,The statements
block will be executed once agin.This process of repeated execution continue
untill the test condition finally becomes false.
2. do-while loop:-
It is an alternative form of while loop.The only difference between while
and do while is the minimum no of execution of while is ‘0′ for mininum
no of execution of dowhile is ‘1′.
syn:-
do
{
statements;
}while(test condition);
First the statement block will be executed and then test
condition will be evaluated.If the condition is true then
the statement block will be executed once again.This process
of repeated execution continuous until the test condition
finally becomes false.
3. For loop:-
It is the most commonly used loop control statement in
‘C’ language.It consisting of 3 expressions.
syn:-
for(exp1;exp2;exp3)
{
statements;
}
The first expresion is used to initialize the index,
second expression is used to check whether the loop
is to be continued (or) not,third expression is used
to change the index for further iteration(increment
(or) decrement).
Nested Loops:-
Using a loop statement with in another loop statement is known as
Nested loop.
