=====size=====
Syntax:
#include
size_type size() const;
The size function returns the number of elements in the current deque.
For example:
deque myints;
cout << "initial size: " << myints.size() << '\n';
for( int i = 0; i < 5; ++i ) myints.push_back(i);
cout << "after five additions: " << myints.size() << '\n';
myints.insert( myints.begin(), 5, 100 );
cout << "after five insertions: " << myints.size() << '\n';
myints.pop_back();
cout << "after a removal: " << myints.size() << '\n';
The above code produces the following output:
initial size: 0
after five additions: 5
after five insertions: 10
after a removal: 9
