莉露C语言编写题解 2863: 删除单词后缀

解题思路:
暴力破解
注意事项:
str[strcspn(str,"\n")] = '\0';，否则会把\n算进去，er消不掉

参考代码:

#include<stdio.h>

#include<string.h>

int main(){

char str[35];

fgets(str,sizeof(str),stdin);

str[strcspn(str,"\n")] = '\0';

int len = strlen(str);

if(str[len-1] == 'r'&&str[len-2] == 'e'){

str[len-2] = '\0';

}

else if(str[len-1] == 'y'&&str[len-2] == 'l'){

str[len-2] = '\0';

}

else if(str[len-1] == 'g'&&str[len-2] == 'n'&&str[len-3] == 'i'){

str[len-3] = '\0';

}

printf("%s\n",str);

return 0;

}
