将2D数组单个阵列
问题描述：
假设我有一个两维数组。
suppose i have a two D array.
#define ROWS 3
#define COLS 3
char a[ROWS][COLS]= {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'}
};
我怎么能那值复制到一个单一的阵列。我只想要COLS值。
How can I copy values of that to a single array. I want only COLS values.
答
它非常简单。让我们来看看怎么样？ -
Its very simple. Lets see 'how?'-
#define ROWS 3
#define COLS 3
#include<stdio.h>
#include<conio.h>
char a[ROWS*COLS]={'1','2','3','4','5','6','7','8','9'};
void main()
{
for(int i=0; i<ROWS*COLS;i=i+COLS)
{
for(int j=0; j<COLS; j++)
{
printf("%c\t",a[i+j]); //access array
}
printf("\n");
}
getch();
}
