Lab Tips

Lab 8

Using End of file marker in C. Try:

        while(!feof(stdin))

Lab 7

Just look at the pseudocode that has been provided for you as a help for solving Lab 7 assignment.

If you think your ideas are better than mine, go ahead. and do that.

Note:- In the code below I have done thw hole thing in a single file whereas you are expected to do it in seperate files. Do not forget to do that, because that contains a substantial %age of points.

1. pseudocode

ENUM Discussion

An enumeration is a data-type, where the members are constants thar are written as identifiers, though they have signed integer values. These constants represents values that can be assigned to corresponding enumeration variables. So, a enum definition look like

typedef enum {member1, member2, . . . , member m} var_name;

An example can be

 

A variation to this can be

 

 

Now I can use the above example in a piece of my code

 

Now if I have the prototype of the get_value function as int get_value(); then based upon what the function is returning I can switch. If it is returning 0, I print black and if it prints 1 then blue and for everything else prints others.

I hope that helped :)

Lab 6

 If you are confused about call by reference, then looking at the following small example may help. In this problem, we will swap 2 numbers in a function and print them from main. Thus we will be requiring call by reference since we are not able to return two values from the function.

The code is not proper commented. Comment your code properly

1. swap.c (the main function)
2. swapn.c (function where the swap occurs)
3. proto.h (header file) 
4. Makefile
