MiniProjects in C++

1.  You have 10 bullets to hit 15 opponent soldiers standing as a unit in rows and columns. Use minimum bullets to hit maximum soldiers.

#include <iostream>
using namespace std;
int main() {

  //define location of opponent Soldiers
   int opponent[3][5] = { {0,0,1,0,0},{0,1,0,1,0},{1,0,0,0,1}};
  //number of bullets
    int bullets = 10;
    int killed=0;
    int row, column, usedbullet = 0;
    while (usedbullet <= 10){
        cout << "Enter row number 0 to 2 : "<<endl;
        cin >> row;
        cout << "Enter column number 0 to 4 : " << endl;
        cin >> column;
        usedbullet++;
        if (opponent[row][column] == 1) {
            cout << " Wow! You hit the target !! "<< endl;
            killed++;
            opponent[row][column] = 0;
        }
        else
            cout << "You missed the target !! Continue firing " << endl;
    }
    cout << "You killed "<< killed << " number of opponentsoldiers" <<endl;
}
