Question

(Write a program, and show the output too) C programming

We will write functions in three file :

1. deposit.c

void deposit ( float *bal, float amount )

{

*bal = *bal + amount;

}

2. withdraw.c

void withdraw ( float *bal, float amount )

{

*bal = *bal - amount;

}

3. atm.c

int main ( )

{

float balance = 200.00 ;

deposit ( &balance , 10 ) ;

printf ( " Balance %f " , balance ) ;

withdraw ( &balance, 20 ) ;

printf ( " Balance %f " , balance ) ;

}

Create a make file to compile and link all three files.

Do not change the names of the three files: deposit.c , withdraw.c and atm.c

I will use your makefile to compile my versions of the files.

1. Just submit the makefile.

2. Your makefile should be able to compile individual files: deposit.c and withdraw.c

3. Your makefile should create a executable file : atm which I will execute and check. In other words, your makefile should have a target named atm will generate the executable

4. Your makefile should also have a target named clean that will erase all *.o files.

Make sure you don't delete *.c or *.txt files.

Explanation / Answer

Following is the required makefile. Place it in same folder as other .c files with name "makefile"

withdraw: withdraw.c
   gcc -c withdraw.c

deposit: deposit.c
   gcc -c deposit.c

atm: atm.c withdraw.c deposit.c
   gcc -o atm atm.c deposit.o withdraw.o

clean:
   rm *.o
