C++程序制表

效果图如上，利用循环和转义字符\t，记住外层循环控制行，内层循环控制列就OK。

#include <iostream>
#include <string>
using namespace std;
int main() {
  string stu_names[]{ "刘备","关羽","张飞" };
  string course_names[]{ "语文","数学","英语" };
  const int ROW = 3;
  const int COL = 3;
  double scores[ROW][COL];
  for (int i = 0; i < ROW; i++) {
    for (int j = 0; j < COL; j++) {
      cout << stu_names[i] << "的" << course_names[j] << "成绩：";
      cin >> scores[i][j];
    }
  }
  cout << '\t';
  for (int i = 0; i < COL; i++) {
    cout << course_names[i] << '\t';
  }
  cout << endl;
  for (int i = 0; i < ROW; i++) {
    cout << stu_names[i] << '\t';
    for (int j = 0; j < COL; j++) {
      cout << scores[i][j] << "\t";
    }
    cout << endl;
  }
  system("pause");
  return 0;
}
