The document discusses different types of loops in C programming: for loops, while loops, and do-while loops. For loops allow initialization of a variable, specify a condition, and how to increment the variable. While loops repeatedly execute code as long as a condition is true. Do-while loops are similar but check the condition at the bottom of the loop, so the code executes at least once. Examples of each loop type are provided.

3. Loop
 There may be a situation, when you need to execute a block
of code 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 and following is the general form
of a loop statement in most of the programming languages

4. Loops In C
Entry control loop
 for loop
 while loop
Exit control loop
 do while loop

5. for loop
• The traditional for loop found in C requires 3
parts:
1) Initialization
2) Condition
3) Increment

6. While loop
• A while loop statement in C programming
language repeatedly executes a target
statement as long as a given condition is true.

7. Do while loop
• which test the loop condition at the top of the
loop, the do...while loop in C programming
language checks its condition at the bottom of
the loop.
• A do...while loop is similar to a while loop,
except that a do...while loop is guaranteed to
execute at least one time

8. For loop
Syntax
for ( variable initialization; condition; variable update )
{
Code to execute while the condition is true
}
Example
for (j=0;j<5 ;j++)
{
printf(“Hai”);
}

9. While loop
Syntax
while (expression)
{
// execute statements
}
Example
int i = 10;
while ( i > 0 )
{
printf("Hello %dn", i );
i = i -1;
}

10. do While loop
Syntax
do
{
statement(s);
}
while( condition );
Example
int a = 1;
Do
{
printf("value of a: %dn", a);
a = a + 1;
}
while( a <= 10 );
