The char type in C is an integer which gets decoded as a character. You can print the char's numerical type. https://github.com/pereiradaniel/beginning_c/blob/master/ch2/char.c // Chars // Daniel Pereira, 16 November 2022. // Display a char and it's numerical value. #include <stdio.h> int main(int argv, char* argc[]) { char c = 0; printf("Enter a character: \n"); scanf(" %c", &c); printf("The character: %c\nIt's numerical value: %d\n", c, c); return 0; } https://github.com/pereiradaniel/beginning_c/blob/master/ch2/char.txt ==87== Memcheck, a memory error detector ==87== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==87== Using Valgrind-3.15.0 and LibVEX; rerun with -h for copyright info ==87== Command: ./char ==87== Enter a character: X The character: X It's numerical value: 88 ==87== ==87== HEAP SUMMARY: ==87== in use at exit: 0 bytes in 0 blocks ==87== total heap usage: 2 al...
