Suppose that you have three programs that are suppose to print a house diagram in a collaborative manner.

(i) prog1.c

#include /* Input/Output */

#include /* General Utilities */

int main()

{

printf( ^^^^^^^^^^^^ );

printf( ^^^^^^^^^^^ ^^^^^^^^^^^ );

printf(^^^^^^^^^^^ ^^^^^^^^^^^ );

printf( | | );

printf( | | );

exit(1);

}

(i) prog2.c

#include /* Input/Output */

#include /* General Utilities */

int main()

{

printf( | | );

printf( | | );

printf( | ^^^^^^^^^^^ ^^^^^^^^^^^ | );

printf( | ^ ^ ^ ^ | );

printf( | ^ ^ ^ ^ | );

printf( | ^ ^ ^ ^ | );

exit(1);

}

(i) prog3.c

#include /* Input/Output */

#include /* General Utilities */

int main()

{

printf( | ^ ^ ^ ^ | );

printf( | ^ ^ ^ ^ | );

printf( | ^ ^ ^ ^ | );

printf( | ^^^^^^^^^^^ ^^^^^^^^^^^ | );

printf( | | );

printf( | | );

printf( ______________________________________________ ); | ");

exit(1);

}

1. Write a c program (name it as house1.c) that draws a 1-story house diagram correctly. Your program should use the following system calls:

fork()

any variant of the exec class system calls

waitpid()

You have to remember prog1.c, prog2.c and prog3.c should be executed in a specific order in a synchronized manner, i.e., prog2 initiates its execution after prog1 is finished and prog3 should be initiated after prog2 is finished!

2. Write a c program (name it as house2.c) that draws a 2-story house diagram correctly. Your program should use the following system calls:

fork()

any variant of the exec class system calls

waitpid()

You have to remember prog1.c, prog2.c and prog3.c should be executed in a specific order in a synchronized manner, i.e., prog2 initiates its execution after prog1 is finished and prog3 should be initiated after prog2 is finished!
