Code Maintenance & Programming Rules

 This guide outlines essential best practices spanning code style, architectural design, debugging, testing, performance, and portability—all aimed at reducing the long-term cognitive load of code maintenance. 🎨 1. Style Code is written for humans to read, and only incidentally for computers to execute. Variable Naming : Use descriptive names for global variables, and short names for local variables. Precision and Consistency : Use active names for functions (e.g., calculateTotal ). Above all, keep your coding style consistent throughout the project. Structure & Expressions : Use a consistent indentation and brace ( {} ) style to show program structure visually. Use the natural form for expressions. Use parentheses to make the semantics unambiguous. Break up overly complex expressions to keep them clear. Side Effects & Macros : Beware of functions with side effects. Avoid function-like macros; if unavoidable, parenthesize the macro body and arguments carefully. Magic Numbe...

高中生程式解題系統:排序 Sorting


題目連結 http://zerojudge.tw/ShowProblem?problemid=a104

雖然排序演算法有很多種,C++也有內建的函數,所以直接用內建函數 sort 來解,其他排序演算法可參考 Python 排序演算法範例 一文。

程式碼:
#include <iostream>
#include <algorithm>
using namespace std;

int main(int argc, char** argv) {
 int n;

 while(cin >> n) 
 {
  int data[n];
  for(int i = 0; i < n; i++)
   cin >> data[i];
  
  sort(data, data+n);
  
  for(int i = 0; i < n; i++)
   cout << data[i] << " ";
   
  cout << endl;
 }

 return 0;
}
