Question

7) Implement a two-dimensional grid with a one dimensional array. a) Implement an empty array of four integers. D) Request four integers from the console and store them into the array. In this array, the index represents a column, the value a row. c) Implement an output function to display the array as a two-dimensional grid of X's and dots where x is an array coordinate. Example output (input is bold and italicized) : Enter 4. row values (from 0 to 3): 3 0 2 1 .8 . ... X

#include <iostream>
using namespace std;

void output(int arr[4]){
   int i,j;
   for(i = 0;i<4;i++){
      for(j = 0;j<4;j++){
         if(i==arr[0] && j==0){
            printf("X ");
         }
         else if(i==arr[1] && j==1){
            cout<<"X ";
         }
         else if(i==arr[2] && j==2){
            cout<<"X ";
         }
         else if(i==arr[3] && j==3){

            cout<<". ";
         }
      }
      cout<<endl;
   }
}

int main () {
   int arr[4];
   int i;
   cout<<"Enter 4 row values (from 0 to 3): ";
   for(i = 0;i<4;i++){
      cin>>arr[i];
   }
   output(arr);
   return 0;
}
