Question

c语言编程题：一个3*4的二维数组中存放1~12共12个数，输入行数和列数显示对应的数组元素的值？

Answer 1

#include<stdio.h>
void main()
{
int a[3][4]={1,2,3,4,5,6,7,8,9,10,11,12};
int i,j;

while(1)
{
printf("请输入行数[1,3]和列数[1,4]:");
scanf("%d%d",&i,&j);
if (i<1||i>3 || j<1||j>4)
{
break;
}
printf("%d\n",a[i-1][j-1]);
}
}

Answer 2

#include<stdio.h>

int main()
{
int a[3][4]={};
int i,j;
for(i=0;i<3;i++)for(j=0;j<4;j++)a[i][j]=i*4+j;
scanf("%d%d",&i,&j);
printf("%d\n",a[i][j]);
return 0;
}
