Try to use string class for that

The string class implements the syntax you're trying to use, i.e. assigning strings with = and comparing them with ==. If you don't want to use the string class then you need to use strcpy and strcmp instead.

p=newpass won't work because p is const. And p==pass will evaluate FALSE because these pointers point to different places. p==pass compares the pointers, not the string contents.

    p=newpass;
    
    cout<<"\n Enter the password = ";
    cin>>pass;
    
    if(strcmp(p,pass)==0)
    {
        cout<<"\n Password is correct";
        getchar();
    }
    else
    {
        cout<<"it was incorrect";
        getchar();
    }
    getchar();
    return 0;
}

I thought that way, I think is better for c++

Code:
#include <iostream>
#include <string>
using namespace std;

int main()
{
string newpass;
string p;
string pass;
cout<<"Enter your new pass word = ";
cin>>newpass;

cout<<"You entred this password = "<<newpass;
p=newpass;

cout<<"\n Enter the password = ";
cin>>pass;

if(p==pass)
{
cout<<"\n Password is correct";

}
else
{
cout<<"it was incorrect";

}

return 0;
}
