我一直控制到达无效功能的结束.我究竟做错了什么？

Question

location pick(void){    // generates a random location
     location get;
     get.x = rand() % FIELD_SIZE + 1;
     int forY = rand() % FIELD_SIZE +1;
    switch(forY){
    case 1:
        get.y = 'a';
            break;
    case 2:
        get.y = 'b';
            break;
    case 3:
        get.y = 'c';
            break;
    case 4:
        get.y = 'd';
            break;
    case 5:
        get.y = 'e';
            break;
    }

}

Answer 1

你在return get;功能结束时失踪了.

Answer 2

确保return get;你的功能!

否则,您要将函数声明为void pick.
