数据结构复习第三章:动态数组

#include<stdio.h> #include<stdlib.h> int main() { int i,j,k; int n1,n2,n3; int ***arr = NULL; scanf("%d %d %d",&n1,&n2,&n3); arr = (int ***)calloc(n1,sizeof(int **)); for(i = 0;i < n1;i++) { arr[i] = (int **)calloc(n2,sizeof(int*)); for(j = 0;j < n2;j++) { arr[i][j] = (int*)calloc(n3,sizeof(int)); for(k = 0;k<n3;k++) { arr[i][j][k] = i+j+k+1; printf("%d ",arr[i][j][k]); } } } for(i=0;i<n1;i++) { for(j=0;j<n2;j++) { free(array[i][j]);//释放第三维指针 } } for(i=0;i<n1;i++) { free(array[i]);//释放第二维指针 } free(array);//释放第一维指针 }
