从键盘任意输入一个字符,编程判断该字符是数字字符、英文字母、空格还是其他字符。 **输入格式要求:提示信息:"Press a key and then press Enter:" **输出格式要求:"It is an English character!n" "It is a digit character!n" "It is a space character!n" "It is other character!n" 程序运行示例1如下: Press a key and then press Enter:A It is an English character! 程序运行示例2如下: Press a key and then press Enter:2 It is a digit character! 程序运行示例3如下: Press a key and then press Enter: It is a space character! 程序运行示例4如下: Press a key and then press Enter:# It is other character!
#includemain() { char ch; printf("Press a key and then press Enter:"); ch = getchar(); if (ch >= 'a' && ch <= 'z' || ch >= 'A' && ch <= 'Z') { printf("It is an English character!n"); } else if (ch <= '9' && ch >= '0') { printf("It is a digit character!n"); } else if (ch == ' ') { printf("It is a space character!n"); } else { printf("It is other character!n"); } }
