    struct plant user;
    zero(arr);
    putInStruct(arr);
    input(&user);
    comparison(user,arr);
}

它给了我以下错误:

Error   10  error C2371: 'print_plant' : redefinition; different basic types    d:\my documents\visual studio 2010\projects\rrr\rrr\dasd.c  205

我该怎么办？

Answer 1

您甚至在声明函数之前就调用了该函数。将 print_plant 的声明移到使用它的代码之上。
