The document explains pattern printing using nested for loops and different types of loops in C programming, including while loops and do-while loops. It provides code examples for printing the first ten natural numbers using both while and do-while loops. The document focuses on the syntax and structure of these loops.

1. NESTED FOR LOOP (Pattern Printing)

2. PATTERN PRINTING USING NESTED FOR LOOP

5. WHILE LOOP
(entry control loop)
while(condition)
{
body of the loop;
}
DO WHILE LOOP
(exit control loop)
do
{
body of the loop;
}while(condition);

6. PRINTING OF 1ST
TEN NATURAL NUMBERS
USING WHILE LOOP
#include<stdio.h>
void main()
{
int n=1;
while(n<=10)
{
printf(“%dn”,n);
n++;
}
}
USING DO WHIEL LOOP
#include<stdio.h>
void main()
{
int n=1;
do
{
printf(“%dn”,n);
n++;
}while(n<=10);
}
