Its crazy, I know.

Well, don't keep us in suspense!

Code:

if (isalpha(str1[i]))
          {
               printf("\n%c", str1[i]);
           }
          else 
          {
               printf("\n%c", str1[i]);
          }

Isn't this a pointless if statement? Id does the same thing no matter what the result of the condition.

I'm not using a Microsoft Compiler, I'm using MingW, so I suppose the problem is not related to that.

I've followed $l4xklynx suggestion and used fgets for all inputs. Also read the faq about input at Cprogramming.com FAQ > How do I get a number from the user (C) and decided to use this:

Code:

char buf[BUFSIZ];
  float i;
  
  printf ("Enter your number: ");
  
  if (fgets(buf, sizeof(buf), stdin) != NULL)
  {
    i = atof(buf);
    printf ("You entered %f\n", i);
  }

This is good for what I want and works fine!

For strings and chars I also used fgets. Thank you all for the kind responses and help.
