生成一个C语言数独使之能在dev c++程序中运行

以下是一个简单的C语言数独程序，可以在Dev C++中运行：

#include <stdio.h>

#define N 9
#define UNASSIGNED 0

int grid[N][N];

void printGrid() {
    for (int row = 0; row < N; row++) {
        for (int col = 0; col < N; col++) {
            printf("%d ", grid[row][col]);
        }
        printf("\n");
    }
    printf("\n");
}

bool findUnassignedLocation(int &row, int &col) {
    for (row = 0; row < N; row++) {
        for (col = 0; col < N; col++) {
            if (grid[row][col] == UNASSIGNED) {
                return true;
            }
        }
    }
    return false;
}

bool usedInRow(int row, int num) {
    for (int col = 0; col < N; col++) {
        if (grid[row][col] == num) {
            return true;
        }
    }
    return false;
}

bool usedInCol(int col, int num) {
    for (int row = 0; row < N; row++) {
        if (grid[row][col] == num) {
            return true;
        }
    }
    return false;
}

bool usedInBox(int boxStartRow, int boxStartCol, int num) {
    for (int row = 0; row < 3; row++) {
        for (int col = 0; col < 3; col++) {
            if (grid[row+boxStartRow][col+boxStartCol] == num) {
                return true;
            }
        }
    }
    return false;
}

bool isSafe(int row, int col, int num) {
    return !usedInRow(row, num) && !usedInCol(col, num) && !usedInBox(row - row%3, col - col%3, num);
}

bool solveSudoku() {
    int row, col;
    if (!findUnassignedLocation(row, col)) {
        return true;
    }
    for (int num = 1; num <= 9; num++) {
        if (isSafe(row, col, num)) {
            grid[row][col] = num;
            if (solveSudoku()) {
                return true;
            }
            grid[row][col] = UNASSIGNED;
        }
    }
    return false;
}

int main() {
    // Enter the sudoku puzzle here:
    int puzzle[N][N] = {
        {5, 3, 0, 0, 7, 0, 0, 0, 0},
        {6, 0, 0, 1, 9, 5, 0, 0, 0},
        {0, 9, 8, 0, 0, 0, 0, 6, 0},
        {8, 0, 0, 0, 6, 0, 0, 0, 3},
        {4, 0, 0, 8, 0, 3, 0, 0, 1},
        {7, 0, 0, 0, 2, 0, 0, 0, 6},
        {0, 6, 0, 0, 0, 0, 2, 8, 0},
        {0, 0, 0, 4, 1, 9, 0, 0, 5},
        {0, 0, 0, 0, 8, 0, 0, 7, 9}
    };

    // Copy the puzzle into the grid
    for (int row = 0; row < N; row++) {
        for (int col = 0; col < N; col++) {
            grid[row][col] = puzzle[row][col];
        }
    }

    // Solve the puzzle
    if (solveSudoku()) {
        // Print the solution
        printGrid();
    } else {
        printf("No solution exists\n");
    }

    return 0;
}

将上述代码复制到Dev C++中的一个新项目中，编译并运行该程序即可。
