命令行选项创建文件的方式

>animal -cat

>animal -dog

void main(int argc, char **argv){
if(argv[1][0] == \'-\' && argv[1][1] == \'c\' && argv[1][2] == \'a\' && argv[1][3] == \'t\')
    printf(\"meow\");
if(argv[1][0] == \'-\' && argv[1][1] == \'d\' && argv[1][2] == \'o\' && argv[1][3] == \'g\')
    printf(\"bow\");
}

     animal -cat  

how to do ?

is there another way to receive option value?

char name[10];
char date[9];

fgets(name,10,stdin);
fgets(date,9,stdin);
