void push(struct point p) { stack[top++] = p; }

您提供的代码片段是一个C语言函数的定义，该函数名为`push`，用于将一个结构体变量`p`压入一个栈中。这个栈是使用数组实现的，并且使用`top`变量来跟踪栈顶的位置。下面是该函数的详细解释：

void push(struct point p)
{
    stack[top++] = p;
}

1. `void push(struct point p)`：这是一个函数定义，表示该函数名为`push`，无返回值（`void`类型），它接受一个类型为`struct point`的参数`p`。`struct point`应该是一个已经定义好的结构体类型，用于存储点的坐标等信息。

2. `struct point p`：这个参数`p`是一个结构体变量，它将被压入栈中。

3. `{stack[top++] = p;}`：这是函数的执行体，只包含一条语句。`stack`是一个数组，用于存储栈中的元素。`top`是一个整型变量，用来表示栈顶的位置，并且它在使用前应该已经正确初始化，并在栈的边界内。`top++`表示先取出`top`的值用于赋值操作，然后将`top`的值加1，即将栈顶指针上移一个位置，为下一个元素做准备。这样，传入的结构体`p`就被存储在新的栈顶位置。

需要注意的是，这个函数只展示了如何压入一个元素，但没有展示栈的初始化、空间溢出检查以及栈的其他操作（如弹出元素）。在实际应用中，需要配合完整的栈操作函数来确保程序的正确性和稳定性。
