putchar(variable ) and printf("%c", variable)

Question

What is the difference between putchar() and printf("%c", variable), as both do the same thing.

Answer 1

In this particular case, they do almost the same, except:

- putchar(c) returns the char written.
- printf returns the total number of characters written.

printf is more resource hungry...
