Please explain what this code is doing (someChar - 48)

Question

I\'m going through some practice problems, and I saw this code:

#include 
#include 

int main(void) {
   char* s = \"357\";
           


        

Answer 1

I suggest writing a test program to see what the values of s[] display. You might also print out all the values for each entry in "0123456789".

I think you'll quickly realize what it's doing, although this code is relying on ASCII encoding.

Have fun!
