这个程序我做对了吗?

任务是用回溯法完成8皇后二维数组程序。

#include <iostream>
using namespace std;
int main() {
    int b[8][8] = { 0 };
    int r, c, i;
    int count = 1;
    b[0][0] = 1;
    c = 0;
nextColumn:
    c++;
    if (c == 8)
        goto print;
    r =- 1;
nextRow:
    r++;
    if (r == 8)
        goto back;
    for (i = 0; i < c; i++) {
        if (b[r][i] == 1)
            goto nextRow;
    }
    for (i = 0; (r - i) >= 0 && (c - i) >= 0; i++) {
        if (b[r - i][c - i] == 1)
            goto nextRow;
    }
    for (i = 0; (r + i) < 8 && (c - i) >= 0; i++) {
        if (b[r + i][c - i] == 1)
            goto nextRow;
    }
    b[r][c] = 1;
    goto nextColumn;
    c--;
    if (c == -1)
        return 0;
    r = 0;
    while (b[r][c] != 1)
        r++;
    b[r][c] = 0;
    goto nextRow;
    cout << endl;
    cout << "Result No." << count << endl;
    cout << endl;
    for (r = 0; r < 8; r++){
        for (int c = 0; c < 8; c++){
            cout << b [r][c];
        }
        cout << endl;
    }
    count++;
    goto back;
}
