How do you create a really large matrix (i.e. 3500x3500) in C
without having the program crash? I can only reach up to 2500.
It must have something to do with lack of memory. Please help!

using Dynamic memory allocation,you can create large array size.
example:m=1000000,n=1000000
void enter(int m,int n)
{
int i,j;
long int c=0;
matrix=new long int*[m]; /*m is row size*/
for(i=m-1;i>=0;i--)
{
matrix[i]=new long int[n]; /*n is col size*/
for(j=0;j<n;j++)
{
matrix[i][j]=++c;
}
delete matrix[i];
}
}
