Thread: 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
