Question 1: [Marks 20]
In Linux Ubuntu flavor, write a program in C language to do the following tasks.
1) Use fork ( ) system call to create a child process.
2) Child process should first take student name as input and then it should display student name that it takes from user. At last, child process should display numbers from 0 to 5.
3) Parent process should first take VU Student ID as input and then it should display VU Student ID that it takes from user. At last, parent process should display numbers from 6 to 10.

Student ID is: BC070651121
parent: 6
parent: 7

parent: 9

5) Execute this program on Linux Ubuntu. Take screen shots of your program that you write in C,
Commands that you used to run your program in Linux Ubuntu and the out put displayed by your
program. After taking screen shots, send these screen shots to me properly in your assignment.

Note:
1) Do not write your program in other languages like Java, C++ etc. Write your program only in C language.
2) Do not execute your program in other operating systems like Windows, Mac etc. Execute your program
only in Linux Ubuntu flavor.
