How I can place number from a String value of
S1("4545645486465") to a vector Vec.. The trick part is that I have to place 4 digits in each cell of the vector. Example:

string s1("468648578468486846845")
vector<int>Vec
void main()
{
...
...
...
...

}
Vec[0]=4686
Vec[1}=4857
Vec[2]=8468
....Vec[n]
....
Please Help me..
