Help understanding a Code

Code:

---

#include <iostream.h>

int main()
{
    int i=0, j=0;
    char s1[40]="string 1", s2[35]="string 2", st[75];
    while(s1[i])
    {
        st[i]=s1[i]; ++i;
    }
    while ((*(st+i)=s2[j]) !=0)
    {
        ++i; ++j;
    }
    cout <<st;
}

---

Ok this is the code.

Code:

---

    while ((*(st+i)=s2[j]) !=0)
    {
        ++i; ++j;
    }

---

In this peace of code i dont understand what the '*' is doing and i dont understand why is it important, but when i remove it the compiler returns an error.

Can someone tell me pls what is that '*' for??

Tks

Array and pointer notation are closely associated with one another (note: this is not saying that arrays and pointers are the same thing - they're not).

But
*( array + index ) is just another way of saying array[index]


> #include <iostream.h>
You might want to get a more modern C++ compiler, if these are the header files you're including.
Modern C++ has
#include <iostream>

It's "de-referencing" a pointer. You have a pointer pointing at a location in memory, to access the thing it is pointing to, you need to de-reference it.

Tks dudes, i got the idea :) and ty for the sugestion Salem.
