Input/ Output alternatives for printf/scanf
c, printf, scanf
Solution
No, neither `printf` nor `scanf` is really needed for this.
The obvious alternatives would be to read the input with something like `getc` or `fgets` and convert from characters to numbers with something like `strtol`.
On the output side, you'd more or less reverse that, converting from numbers to characters (e.g., with `itoa` which is quite common, though not actually standard), then printing out the resulting string (e.g., with fputs).
Problem
It may sound strange that knowing a lot about iOS and having some experience in .net, I am a newcomer to C. Somewhere I got this target to find average of n numbers without using `printf` and `scanf`. I don't want the code for the program but I am seeking alternatives to the mentioned functions. Is code with `printf/scanf` required here? Also do let me know if my query stands invalid.
