Question

I am trying to print the value of each character in a string in this format:

Code 2 in set 0 has value: 41 42

Code 6 in set 0 has value: 41 42 43 44 45 46

I am trying to do this by:

printf("Code %d in set %d has value: %.*s\n", ndx, set, getCode(cs[set],ndx).size, getCode(cs[set],ndx).data);

But when I do this it prints the characters associated with the value rather than the value itself. How should I go about printing the data in the format specified?

Answer 1

You’re printing your array as a string. Instead loop through each character and print its decimal value:

int i;
printf("Code %d in set %d has value: ", ndx, set);
for (i = 0; i < getCode(cs[set],ndx).size ; i++) {
  printf("%d ", getCode(cs[set],ndx).data[i]);
}
puts(""); //print a newline
