The document discusses different types of loops in programming - for loops, while loops, and do-while loops. For loops use an initialization, condition, and increment statement to iterate through a code block a set number of times. While loops continuously execute a code block as long as a condition remains true. Do-while loops are similar to while loops but execute the code block at least once even if the condition is false. Examples are provided to demonstrate each type of loop printing out numbers from 10 to 1.

1. LOOPS

2. FOR LOOP
The syntax of for loop is
for(initialisation;condition checking;increment)
{
set of statements
}
The Example for for loop:
// Program to print Hello 10 times
for(i=0;i<10;i++)
{
printf(“Hello”);
}

3. WHILE LOOP The syntax for while loop
while(condition)
{
statements;
}

4. Example for while loop:
a=10;
while(a != 0)
{
printf(“%d/t”,a);
a- -;
}
Output:
10 9 8 7 6 5 4 3 2 1

5. DO WHILE LOOP The syntax of do while loop
do
{
set of statements
}while(condition)

6. Example of do-while loop:
i=10;
do
{
printf(“%d/t”,i);
i--;
}while(i!=0)
Output:
10 9 8 7 6 5 4 3 2 1

7. Example of do-while loop:
i=10;
do
{
printf(“%d/t”,i);
i--;
}while(i!=0)
Output:
10 9 8 7 6 5 4 3 2 1
