#include<cstdio> int main() { char ch; while (scanf("%c", &ch) != EOF) { if (ch >= '0'&&ch <= '9') printf("It is a digit character!\n"); else if ((ch >= 'A'&&ch <= 'Z') || (ch >= 'a'&&ch <= 'z')) printf("It is an English character!\n"); else if (ch == ' ') printf("It is a space character!\n"); else printf("It is other character!\n"); getchar(); } }
