Thread: why can't i return Array from function?

Hello,
I m trying to find saddle point in a matrix. But when i return array from function the program simply doesn't work at all. I get no output even though there's a saddle point in matrix. Here is the code :-

Code:

#include <iostream.h>
#define M 3
#define N 3
int* find_min(int a[M][N],int row)
{
 int *temp,j=1;
 temp=new int[2];
 temp[0]=a[row][0];
 temp[1]=0;
 for(j=1;j<N;j++)
 {
	if(temp[0]>a[row][j])
	{
		temp[0]=a[row][j];
		temp[1]=j;
	}
 }
 return temp;
}
int find_max(int a[M][N],int col)
{
 int i,temp;
 temp=a[0][col];
 for(i=1;i<M;i++)
 {
   if(a[i][col]>temp)
		temp=a[i][col];
 }
 return temp;
}

void saddle(int a[M][N])
{
 int i,max,*min,j;
 for(i=0;i<M;i++)
 {
	min=find_min(a,i);
	max=find_max(a,min[1]);
	if(min[0]==max)
		cout<<"\n\nSaddle Point 

:"<<min[0];
 }
}
int main(void)
{
 int a[M][N]={5,7,3,7,7,9,7,1,2};
 
 saddle(a);

 return 0;
}

This code works perfectly now when i write the above function as :-

Code:

int* find_min(int a[M][N],int row)
{
 int temp[2],j=1;
 temp[0]=a[row][0];
 temp[1]=0;
 for(j=1;j<N;j++)
 {
	if(temp[0]>a[row][j])
	{
		temp[0]=a[row][j];
		temp[1]=j;
	}
 }
 return temp;
}

this is not working. Can anybody tell me why is this wrong?
