Who determines the ordering of characters

Question

I have a query based on the below program -

char ch;
ch = \'z\';
while(ch >= \'a\')
{
    printf(\"char is  %c and the value is %d\\n\", ch, ch);
    ch =         


        

Answer 1

Obviously determined by the implementation of C you're using, but more then likely for you it's determined by the American Standard Code for Information Interchange (ASCII).
