WebJul 29, 2024 · 导言. 今天带来的程序是找出数组或者 Vector 中最大最小值的索引. 在 Python 中,我们可以使用 numpy 库快速实现,那接下来就看看 C++ 是怎么实现的吧. 主要使用到的函数是 max_element 和 min_element. 基本用法如下,分为数组和 vector:. max_element(arr, arr +arr_length) //arr 是 ... WebSep 14, 2016 · C++: this often means a reference. For example, consider: void func(int &x) { x = 4; } void callfunc() { int x = 7; func(x); } As such, C++ can pass by value or pass by reference. C however has no such pass by reference functionality. & means "addressof" and is a way to formulate a pointer from a variable. However, consider this:

For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine.
