如何用几种方法处理1个数组

Question

I have Multidimensional array in my struct i want to work with this array using few methods, i think i should use double pointer but i have no idea how to do it

struct generator {
    char r[26][max];

        void set();
    void display();
};

void generator::set() {
    char *tab = new char[max];
    int k = 0;

    cin >> tab;

    while (tab[k] != '\0') {    
        r[0][k] = tab[k];
        k++;
}
void generator::display(){
    cout << r[0][1];    // should display first letter of string
}

Answer 1

in

  cout << r[0][1]; // should display first letter of string 

the comment is wrong, that displays the second letter, first letter is at index 0

Adding enough definitions and missing '}' to compile and execute :

#include <iostream>
using namespace std;

#define max 10

struct generator {
  char r[26][max];

  void set();
  void display();
};

void generator::set() {
  char *tab = new char[max];
  int k = 0;

  cin >> tab;

  while (tab[k] != '\0') {    
    r[0][k] = tab[k];
    k++;
  }
}

void generator::display(){
  cout << r[0][1];    // should display first letter of string
}

int main()
{
  generator g;
  g.set();
  g.display();
  cout << endl;
}

Compilation and execution :

/tmp % g++ -pedantic -Wall -Wextra g.cc
vxl15036 /tmp % ./a.out
