在C中动态分配3D矩阵

#include <stdio.h>
#include <stdlib.h>

int main() {
    int rows, cols, depth;
    printf("Enter the number of rows: ");
    scanf("%d", &rows);
    printf("Enter the number of columns: ");
    scanf("%d", &cols);
    printf("Enter the depth: ");
    scanf("%d", &depth);

    // 动态分配内存
    int*** matrix = (int***)malloc(rows * sizeof(int**));
    for (int i = 0; i < rows; i++) {
        matrix[i] = (int**)malloc(cols * sizeof(int*));
        for (int j = 0; j < cols; j++) {
            matrix[i][j] = (int*)malloc(depth * sizeof(int));
        }
    }

    // 初始化矩阵元素
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            for (int k = 0; k < depth; k++) {
                matrix[i][j][k] = i + j + k;
            }
        }
    }

    // 访问和打印矩阵元素
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            for (int k = 0; k < depth; k++) {
                printf("%d ", matrix[i][j][k]);
            }
            printf("\n");
        }
        printf("\n");
    }

    // 释放内存
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            free(matrix[i][j]);
        }
        free(matrix[i]);
    }
    free(matrix);
