Creation and use of strings in C++

C++ provides following two types of string representations:

• The C-style character string.

• The string class type introduced with Standard C++.

The String Class in C++:

The standard C++ library provides a string class type that supports all the operations mentioned above, additionally much more functionality. We will study this class in C++ Standard Library but for now let us check following example:

At this point, you may not understand this example because so far we have not discussed Classes and Objects. So can have a look and proceed until you have understanding on Object Oriented Concepts.

#d6d6d6;">#include 
#include 

using namespace std;

int main ()
{
   string str1 = "Hello";
   string str2 = "World";
   string str3;
   int  len ;

   // copy str1 into str3
   str3 = str1;
   cout  "str3 : "  str3  endl;

   // concatenates str1 and str2
   str3 = str1 + str2;
   cout  "str1 + str2 : "  str3  endl;

   // total lenghth of str3 after concatenation
   len = str3.size();
   cout  "str3.size() :  "  len  endl;

   return 0;
}

When the above code is compiled and executed, it produces result something as follows:

#d6d6d6;">str3 : Hello
str1 + str2 : HelloWorld
str3.size() :  10
