大家好，我是讯享网，很高兴认识大家。

C语言实现输入字母判断是星期几
请输入星期几的第一个字母来判断一下是星期几，如果第一个字母一样，则继续判断第二个字母。例如：程序运行时，提示你"please input first character:" 你输入’f’或者’F’，则程序输出"Friday"，你输入s，则程序进一步提示你"Please input second character:" 此时还需要进一步输入u，程序才输出"Sunday" 如果你输入的字母和任何星期的英文单词首字母都不匹配，则程序需要提示"Illegal input!\n"。

#include "stdio.h" int main(void) { char i,j; scanf("%c",&i); if(i>='a'&&i <='z') i=i-32; if(i>='A'&&i <='Z'){ if(i=='M') printf("Monday"); else if(i=='W') printf("Wednesday"); else if(i=='F') printf("Friday"); else if(i=='S'||i=='T'){ scanf(" %c",&j); if(i=='S'&&j=='u') printf("Sunday"); else if(i=='S'&&j=='a') printf("Saturday"); else if(i=='T'&&j=='u') printf("Tuesday"); else if(i=='T'&&j=='h') printf("Thursday"); else printf("illegal input!\n"); } else printf("illegal input!\n"); } }
