Thread: C in general

hi all

sorry I couldn't find a precise title..
I'm new to C I usually write in JAVA or Visual basics 6, so there are a few things I want to ask you about, I know some questions might seem silly:

1- suppose you have the string "2004004", how can you convert this to a "long" value? in general is there a way in C to convert from Strings to int or long or double?

2-when reading for a txt file, I used the following code:

fscanf(fileName," %s %s %s ", nm, fm, un);
//nm fm and un are string variables so no problem here

if I do this iteratively shouldn't I get the next lines in the file until the feof?

3-I went over the basics in C but I didn't read anything concerning graphics...Is there a way to create GUIs in C? if so can you point me to an online tutorial?

4- and also about random number: how do we generate random numbers?


thanks

that's weird...I have the string.h library in front of me but I couldn't find these functions

thanks a lot
