输入一个字符，判断该字符是大写英文字母，小写英文字母，空格，还是其它字符
看代码
#include <stdio.h>void main(){char c;printf("Enter a char：");c=getchar();if(c<32)printf("The char is control char.");else if(c>='0'&&c<='9')printf("The char is a digit char.");else if (c>='A'&&c<='Z')printf("The char is a captal char.");else if(c>='a'&&c<='z')printf("The char is a lower char.");elseprintf("The char is an other char.");return 0;
