C语言实现动态二维数组

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

void main(int num, char* args[])
{
    int x, y;
    scanf("%d%d", &x, &y);

    int **pp = (int **) malloc(sizeof(int *)*x);
    for(int i = 0; i < x; i++)
    {
        pp[i] = malloc(sizeof(int)*y);
    }

    int n = 0;

    for(int i=0; i < x; i++)
    {
        for(int j = 0; j < y; j++)
        {
            pp[i][j] = n++;
            printf("%d ",pp[i][j]);
        }
        printf("\n");
    }
}
