1.1 函数指针(Pointer to Function) 函数指针是一个指针,它指向函数的入口地址。 简单来说,就是用一个指针变量来保存函数的地址,通过这个指针可以间接地调用该函数。 如果是我们特训营学过项目3的老铁,应该非常熟悉了,我们大量回调函数的应用,就必须要用到函数指针。 1.2 指针函数(Function Returning Pointer) 指针...

func_p is pointer to function(double) returning int 最后翻译为中文: func_p是指向返回int的函数的指针。 类似的在书上总结为: C语言英文描述中文描述 int hoge; hoge is int hoge是int int hoge[10]; hoge is array of int hoge是int数组 int hoge[10][3]; hoge is array(10) of array(3) of...
declare f as pointer to function returning pointer to array 10 of int 46.再论字符串常量 当一个字符串常量出现于表达式中时,它的值是一个指针常量。我们可以对它们进行下标引用、间接访问以及指针运算。 "xyz" + 1 是 'y'处的指针"xyz"[2]
