Re: [algogeeks] Re: whats d problem wid using gets?

[SANDEEP CHUGH]

@PRAVEEN :

with scanf , we can read two or more than two variables at a time
like
scanf("  %s %s"string1, string2)

but with gets we can read only one variable
gets (string1)

we cannot use  gets (string1, string2)

another problem with gets is that although we can read multiword string
but we cannot read multiple strings  like with scanf,,

char str[MAXLINE];
fp=fopen("ABC.txt","r");

syntax:

fgets(str,MAXLINE,fp);

Re: [algogeeks] Re: whats d problem wid using gets?

[kartik sachan]

using gets we can get buffer over as gets doesn't check about the size input
so it mai go to that area where our stack base pointer(think in memory
layout section) is stored so our programmed doenn't return to orignal state
as address is stored there...so it is dangeroues to use

I had once read somewhere that they had used gets() during the first
compilations of unix, and it used to always crash for some test cases.
So after that they stopped using it and alerted everyone of the problem..
