HI,
So the strstr searches the two strings given for the first occurance of the substring? And then returns a pointer?
Yes.
It is a Function that takes two arguments both strings and returns a pointer to the occurance of the first argumrnt in the second ............else returns NULL
Excuse my n00bness, but what's a pointer?
Pointer is a variable that contains the address of another variable.
e.g
when you declare a variable say char str[5]
5 consicutive locations are allocated for str in the memory.........all of them can be independently addressed........when i say
ptr= &str;
The base address of the variable str (first of the 5 consituve location) will be passd on to the ptr.................ptr is a pointer to str
Hope this helps .......
--Good Luck--
