Hey Archit Kar Use address-of operator (&) to store variable ! Ex: scanf("%c",&firstname);

You need to store the name in an array of chars.

Mahmoud 'Carbon' Saghraoui are you sure about that char[] declaration? I think it has to have fixed size, so you must declare size of that array, or make char pointer to allocate memory dynamically

I don't see any mistakes there, you may not understand your own code so let me explain it for you. ----------------------------- char firstname[]; <-- Declared a variable, i've added the '[]' keep 'em printf("what is your name? \n"); <-- This prints 'what is your name' scanf("%s", firstname); <-- Takes the input of the server ----------------------------- If you want to print the name after the input was taken then you can do printf("Your first name is: %s", firstname);
