  The above picture lists the keywords that define data types, and indicates the occupation and value range of different types in 32-bit machines. Next, let's briefly introduce these three data types. 1. Integer: there are two types of integers: signed and unsigned. Signed integers can be regarded as compatible with negative integers, w ...

Codeforces Round #752 (Div. 2) Record high!! A. Era Idea: at first, I thought it was to find a maximum subscript, and then output the maximum minus the maximum subscript.

The standard library and the three enablers of boost_ If series of functions can help us overload template functions. Overloading of general functions Let's take a look at an example of general function overloading: #include <iostream> void print(int i) { std::cout << "Integral: " << i << std::endl; } void print(d ...

If an array has more than one dimension, it can be called a multidimensional array. Let's take a specific look at the relevant knowledge of multidimensional arrays. 1. How to initialize multidimensional arrays int days[4][3]; As above, a two-dimensional array is defined. It can be regarded as an array of one-dimensional arrays. We can initi ...
