please provide me link for the reason of the problem when we use scanf and gets simultaneously…
Hopefully this will help you - http://discuss.codechef.com/questions/24634/gets-in-gcc
Depends on how you’re using it.
For example: If your code snippet is something like this
printf("Enter your roll number: "); scanf("%d", &roll); printf("Enter your name: "); gets(name);
Here you won’t get desired result. Why? Because
gets is reading only the ‘\n’ left by the
You can rectify it by doing:
printf("Enter your roll number: "); scanf("%d\n", &roll); printf("Enter your name: "); gets(name);
name will store the string that you will enter when prompted.
It is pretty simple, no rocket science. Do not make an assumption that there will always be a problem when you use both function simultaneously. If you know the mechanism of how they work then you will always use it in the right manner. Dennis Ritchie didn’t develop C to incorporate these basic I/O flaws. You need to learn it, in a more concrete manner.
sir, more link please!!!
Thanks for sharing
may i know why there is always(or may be) new line character present in the input buffer?
@rudra_saraf >> Because after entering roll number will you hit the Enter or not for the next action to be prompted?
Similarly, in the input test cases there is a newline ‘\n’
