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

#include <stdio.h>

int main(){
int a,b;
scanf("%c",&a);
//printf("%d",a);
//printf("\n%c",a);
if(a>=65 && a<=90){
	b=a-1;
	printf("%c is uppercase, so we should print %c.",b,a);
}
else if(a>=97 && a<=122){
	printf("%c is lowercase, so we should print %c.",a,a);
}
return 0;
