Question

Write a program to place eight queens on an 8 x 8 chessboard in such a way that one queen is to be in each row. A program will use 2 DIMENIONAL array x[r][c] to do this configuration. If x[r] has value c, then in row r there is a queen in column c. Write a program that asks a user to enter the columns that contain queens in the 8 rows. The program then places the queens in these columns (one per row) and prints the board. Make sure 0 is a valid column and you can input 0 and have it display on the checker board like any other number

Answer 1

Code in c++:

#include <iostream>

using namespace std;

int main()
{
  
char arr[8][8];
  
for(int i = 0 ; i <8; i++){
for(int j = 0; j <8; j++){
arr[i][j]='*';
}
}
int input;
for(int i = 0 ; i< 8 ; i++){
while(true){
std::cout << "Enter the column you want to put Queen(Q) in row "<<i+1 <<" (enter number b/w 0-7)" << std::endl;
cin>>input;
if(input>-1 && input <8){
break;
}
cout<<"invalid entry\n";
}
  
arr[i][input] = 'Q';
}
  
for(int i = 0 ; i <8; i++){
for(int j = 0; j <8; j++){
cout<<arr[i][j];
}
cout<<endl;
}

return 0;
}
