deque::pop_front (STL/CLR)

Removes the first element.

    void pop_front();

The member function removes the first element of the controlled sequence, which must be non-empty. You use it to shorten the deque by one element at the front.

// cliext_deque_pop_front.cpp 
// compile with: /clr 
#include <cliext/deque> 
 
int main() 
    { 
    cliext::deque<wchar_t> c1; 
    c1.push_back(L'a'); 
    c1.push_back(L'b'); 
    c1.push_back(L'c'); 
 
// display contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// pop an element and redisplay 
    c1.pop_front(); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    } 
 
a b c b c
