Help giys

Answer 1

Declaration differences?
C has no direct declaration of string. So must use a charecter array.. So string in c are sequence charecter terminated by \0.
Ex:
char a[50]="Solo learn";
In c++:
string a="Solo learn";
In java:
Sting s="Solo learn"; or
String s=news String("Solo learn");

Answer 2

You have to define what string you are talking about.

There are the raw strings like you use them in C, which are basically just arrays of chars with a 0 ('\0') at the end. Functions like printf are designed in a way that they'll recognize this 0 as the end of the line.

Then there are higher types of strings in the different languages that build a casing around the raw material and add certain behaviors and rules.

In C++ that's the type 'string' which you have to include and which has all sorts of methods, like push_back, pop_back and such.

While in C++ strings can be changed, strings in Java are 'immutable', which means that you have to create a whole new object when you want to change a letter or something.

There's probably a lot more to say, but does this give you a bit of a feeling already?
