Thread: Double Hops but why ???

The easy way to fix the "extra newline" problem is to simply add the option to skip it to your scanf call:

scanf( "%c%*c", &myVar );

You can handle this one of two ways:

1) assume your user will enter the correct info, and in which case, just replace this:

Code:

printf ("\nAre you finished using the Newton Raphson's Root finder ?"); 
scanf("%c", &f);

With this:

Code:

printf ("\nAre you finished using the Newton Raphson's Root finder ?"); 
scanf("%c%*c", &f);

2) You can do it the "safer" way, which will read into a buffer then parse the buffer. In this case, use fscanf instead of your regular scanf call.
