unordered_set::size_type

  • Article

The type of an unsigned distance between two elements.

typedef T2 size_type;

Remarks

The unsigned integer type describes an object that can represent the length of any controlled sequence. It is described here as a synonym for the implementation-defined type T2.

Example

 

// std_tr1__unordered_set__unordered_set_size_type.cpp 
// compile with: /EHsc 
#include <unordered_set> 
#include <iostream> 
 
typedef std::unordered_set<char> Myset; 
int main() 
    { 
    Myset c1; 
    Myset::size_type sz = c1.size(); 
 
    std::cout << "size == " << sz << std::endl; 
 
    return (0); 
    } 
 

size == 0
