I have to write a grep program in C and I am not sure where to start. :?:
I need to use strstr() from the standard library, and get it to work; but I dont know how to do that.
And that's only half the program, the second part is "getting strstr() to do case-insensitive searches"... But the professor says it can't; "you know what happens when you know what verb you need, you know what you need it to do, but it isn't available?... you write it" I am not sure what that means and I have no clue what strstr() means! If someone could just help me get started i would really appreciate it. This is my first time taking programming and It is soooo much harder than I thought!
Thanks In Advance!
