When I run this and enter my name I get a single character output.

char cName = '\0';

printf("\n\tGreetings\n");
printf("\nPlease tell us your name: ");
scanf("%c", &cName);
printf("\nWelcome %c", cName);

this is a challenge question from the Michael A. Vine "C-Programming for the absolute beginner." I believe Ive done everything right here as this same formula has worked for Integers. Do I have to change to this?

printf("\nWelcome %.10c", cName);

1) Use code tags please... << !! Posting Code? Read this First !! >>

2) You should usually post compilable code in case people want to test it.

3) Read up on strings a little bit more...

Code:

char cName[10] = {0};

printf("\nGreetings\n");
printf("\nPlease tell us your name : ");
scanf("%9s", cName);
printf("\nWelcome %s", cName);

It should come as no surprise that a char can only hold 1 character...
In C strings are arrays of characters where the last used element of the array is tagged with a trailing 0.
The library functions cooperate to treat these arrays like text.

Ok I have not gone over strings yet. I am self studying so I just follow the chapters in this book. Thanks for the information.
