Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(int argc, const char * argv[])
{
    char word;
    scanf("%c",&word);
    if(word>='a' && word<='z')
    {
        printf("a\n");
        printf("%c is lowercase, so we should print a.\n",word);
        
    }
    if(word>='A' && word<='Z')
    {
        printf("A\n");
        printf("%c is uppercase, so we should print A.\n",word);
        
    }
