Question

怎么把一个二维数组中的数值赋给一个一维数组

Answer 1

单循环也可以：

//---------------------------------------------------------------------------

#include <stdio.h>

int main(void)
{
int a[2][2]={1,2,3,4},b[4],i;

for (i = 0; i<4; i++) {
b[i]=a[i/2][i%2];
printf("%d ",b[i]);
}
return 0;
}
//---------------------------------------------------------------------------

Answer 2

用双循环赋值吧，比如
int a[3][3];
int b[9];
int k=0;
for(int i=0;i<3li++)
for(int j=0;j<3;j++)
{
b[i*3+j]=a[i][j];
}

Answer 3

var a:array[1..100,1..100]of longint;
b:array[1..10000]of longint;
i,j:longint;
begin
readln(n,m);
for i:=1 to n do
for j:=1 to m do
readln(a[i,j]);
for i:=1 to n do
for j:=1 to m do
b[i*j]:=a[i,j];
end.
