Thread: is push_back() a overloaded function ?

I think it would be a problem trying to put an array of integers into a vector because it wouldn't know how large the array is. If you are using vectors you might as well do something like this:

Code:

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<vector<int> > z;
vector<int> y;
y.push_back(0);
y.push_back(1);

z.push_back(y); 

cout<<z[0][0]<<endl;
cout<<z[0][1]<<endl;

}

You might, however, be able to use a char array, provided it is null-terminated:

Code:

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<char* > z;
char y[2];
y[0]='a';
y[1]='b';
y[2]='\0';
z.push_back(y);
cout<<z[0]<<endl;
cout<<z[1]<<endl;

}
