Class: BICTE	Period: 2^nd
Semester: 1^st	Time: 10 minutes
Topic: Looping in C using while

Specific Objectives:

At the end of this topic the students will be able to:

a) Understand the syntax of while loop

b) Use of while loop statement in suitable situation

Teaching Materials:

Whiteboard, Marker, Computer

a) At first, I will revise the topic which was taught last day within one minute.

b) Then I will give the concept of while loop statement with syntax:

Syntax: while(condition)

{

Block of statement;

Increment/decrement;

}

c) I will solve the following program and make students more clear.

Example: Write program in C that display the first 20 natural numbers using while loop.

#include<stdio.h>

#include<conio.h>

void main()

{

int c=1;

while(c<=20)

{

printf(“%d\n”,c);

c++;

}

getch();

}

If you declare the initial value of c as 10, then what will be the output?
