String + int

Question

I just tried this
cout << 1 + "zohal";
And the out put is ohal!!
And check this out if I add 2 the output will be hal
Why??
If I have a string variable and do the same thing it either be a CE or a weird output I tried it
Is there anyway to do the same thing with a string variable?

Answer 1

I'm not a C++ programmer, but I believe it's used to get a substring starting from the index added. For example, if we have a string "Hello World!", and we want to get "World!", we can do:
cout<< 6 + "Hello World!";
This removes the "Hello ".

Answer 2

The same can be written as
const char * a = "name";
std::cout << a + 2;
Or
std::cout << 2 + a;
The last permutation give the same output becouse 'a' is memory address, so if a=3542, 3542+2=2+3542.
and we need to remember that terminator of string literal is \0.
