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];
}
}

You are given any character string. Find the number of sets of vowels that come in the order of aeiou in the given string. For eg., let the given string be DIPLOMATIC. The answer returned must be "The number of sets is 2" and "The sets are "IO and AI". Vowels that form a singleton set must be neglected. Try to post the program executable in gcc or g++ or in java.
