Printing Char and Integer Representations Backwards

Task

Implement the function print_abc_char_and_int_backwards

• Writing a function that takes a null-terminated char[] of characters and prints each character along with its integer (ASCII) value, in backwards order that they appear in the array
• The function signature is

// Given a char[] of characters, print the char representation backwards
// For example:
// Input: abc
// Output:
// c 99
// b 98
// a 97
void print_abc_char_and_int_backwards(char str[]);

Testing

Compiling

• use gcc to compile the program and use ./ to run the program

gcc print_abc_char_and_int_backwards.c -o print_abc_char_and_int_backwards
./print_abc_char_and_int_backwards

Example Uses

• This is how the terminal should look after running these lines

$ gcc print_abc_char_and_int_backwards.c -o print_abc_char_and_int_backwards
$ ./print_abc_char_and_int_backwards
