Value transfer: A formal parameter is a copy of an argument. Changing the value of a formal parameter does not affect the value of an external argument. From the perspective of the called function, the value transfer is one-way (argument - > formal parameter), and the value of the parameter can only be passed in, Cannot transfer out. When ...

Digital amplification Given an integer sequence and magnification x, each integer in the sequence is amplified by x times and output. Time limit: 1000 Memory limit: 65536 input It contains three lines: the first line N represents the length of the integer sequence (N ≤ 100); The second line is N integers (not exceeding the integer range), ...

chart There are two ways to store graphs: adjacency matrix and adjacency table. adjacency matrix A two-dimensional array is used to indicate whether there are edges between vertices and how much weight the edges are. For an undirected graph, the adjacency matrix is a symmetric matrix. The disadvantage is that although the adjacency matrix i ...

What is an adapter adapters play the role of bearing and converter in the flexible combination and application function of STL components. The concept of adapter is actually a design pattern. In the design pattern, the definition of adapter style is as follows: convert one class interface into another class interface, so that classes that ...

Title Description You are given an integer array nums and an integer target. You want to build an expression out of nums by adding one of the symbols '+' and '-' before each integer in nums and then concatenate all the integers. For example, if nums = [2, 1], you can add a '+' before 2 and a '-' before 1 and concatenate them to build th ...

introduction File reading and writing is a function of many applications, and even some applications are developed around the processing of files in a certain format, so file reading and writing is a basic function of application development. Qt provides two basic methods for reading and writing plain text files: Use the IODevice read-write f ...
