CSE Exp-1

This document provides instructions for an introduction to C language experiment. It includes 4 program codes that demonstrate printing messages to the screen. Program Code 1 prints "Hello World" but the output disappears quickly. Program Code 2 adds getch() to prevent this. Program Code 3 adds clrscr() to clear the screen between runs. Program Code 4 demonstrates printing on multiple lines using \n. The objective is to get familiar with the C language and writing programs that display output. Students are assigned homework to write a program displaying their name, ID, department, and university.

Program Code 1
/* Writing a Message */
#include<stdio.h>
main( )
{
printf(Hello World);
}

After finishing the code click on Compile menu, then click on Compile.
If any is shown correct it.
Repeat above two step until Compile shows Success.
Then click on Run menu, then click on Run.

FOR OBJECTIVE-(b)

For Program Code 1, the output screen will be shown for few microseconds and will also
be shown a warning. To avoid this problems the following Program Code should be
followed:

Program Code 2
/* Writing a Message */
#include<stdio.h>
#include<conio.h>
void main( )
{
printf(Hello World);
getch( );
}

After execution Program Code 2, the output will remain in output screen. Therefore,
when we again execute the program, the output of previous execution will also be shown.
To avoid this problem, we have to follow the following program code.

Program Code 3
/* Writing a Message */
#include<stdio.h>
#include<conio.h>
void main( )
{
clrscr( );
printf(Hello World);

#include<conio.h>
void main( )
{
clrscr( );
printf(This is first statement.\n);
printf(This is second statement.);
getch( );
}
