Question

In PHP I remember I can do something like

substr(string,start,length)

now I declare

int array[20];

how can I print only a part of it without using a for loop

for example.

cout << array[1 to 5] << "Here is the breaking point" << array[15 to 20] << endl;

Something like this

I also remember if it was printf there would be something like ^5 or something like saying upto 5

You can use a combination of ostream_iterator and copy (link to ideone):

#include <iostream>
#include <iterator>
#include <algorithm>

using namespace std;

int main() {
    int array[] = {1,2,3,4,5,6,7,8,9,10,11,12,13};
    ostream_iterator<int> out_it (cout," ");
    copy ( array+3, array+6, out_it );
    return 0;
}

The array+3 syntax may look unusual: this is a pointer expression equivalent to &array[3], which produces a pointer. Since you can pass a pair of array pointers where C standard library expects a pair of iterators, this produces the expected results.
