CISC 1110 10714 10715 char pointer

[Manor Perets]

Hi,

Looking forward to class.

I have two problems in CodeLab that I couldn't complete as I'm not familiar with * pointer. I've read up on pointers, some, but I don't know what I should be doing any different to solve the problem.

Am I the only one not done with these two problems?

Any input would be appreciated.

Thanks,

Manor

-----------------

Write a function max that has two C string parameters and returns the larger of the two.

char max(char x, char y){ // I tried 'string' as well

if(strcmp(x,y)>0)

return x;

else return y;

}

Ummm.... That's nice but which class are you looking forward to?
Classes are over! Our next meeting is the final exam.

Oh! Didn't realize that. Thanks for the pointer.
