如何动态分配存储器为一个二维阵列 [英] how to allocate memory dynamically for a two dimensional array

问题描述

我最近一直是一个面试，他们要我写一个长期计划了二维数组（I = 3和j = 2）

动态分配内存

解决方案

 为int * A =（INT *）malloc的（我*Ĵ*的sizeof（INT））;
 

您可以得到 A [K] [1] 与 A [K * I + 1];

I had recently been for a interview and they had asked me to write a programe to allocate memory dynamically for a two dimensional array (i=3 and j=2)

解决方案

int *a = (int*)malloc(i*j*sizeof(int));

You can get a[k][l] with a[k*i+l];
