Reading a Whole Word in C

SOLVED!!

Hello, I cannot seem to find a way to get my program to read a WHOLE word and then so something according to that word.

Basically, my program needs to ask the user about 3 options, to multiply, sum, or exit.

I thought of doing something like this:

Code:

scanf("&#37;c", &option);
switch(option)
  {
         case 'm': printf("%f * %f = %f\n", a,b,c); break;
         ... .... ...
         default : printf("Error!\n); return 0;
  }

But now, I want it to read the whole word, not the first character, I can't find my way around this, Help!

To read an input string of characters option needs to be an array of characters for ex.

Code:

char option[100];
scanf("%s", option);

As you need to perform arithmetic operations on your input it's better to make option a variable of type int or float.

Oh.. Dumb Me..

Thanks, it compiles now and all, had to use some strcmp's to get it working.

Now to define the algorithm for factorial numbers. (n!)
