basic_string::size_type

An unsigned integer type that can represent the number of elements and indices in a string.

typedef typename allocator_type::size_type size_type;

Remarks

It is equivalent to allocator_type::size_type.

For type string, it is equivalent to size_t.

Example

// basic_string_size_type.cpp
// compile with: /EHsc
#include <string>
#include <iostream>

int main( ) 
{
   using namespace std;
   string str1 ( "Hello world" );

   basic_string <char>::size_type sizeStr1, capStr1;
   sizeStr1 = str1.size (  );
   capStr1 = str1.capacity (  );

   cout << "The current size of string str1 is: " 
        << sizeStr1 << "." << endl;
   cout << "The capacity of string str1 is: " << capStr1 
         << "." << endl;
}

The current size of string str1 is: 11.
The capacity of string str1 is: 15.
