C++ Forward_list Library - operator> Function
Description
The C++ function std::forward_list::operator> tests whether first forward_list is greater than other or not.
Declaration
Following is the declaration for std::forward_list::operator> function form std::forward_list header.
C++11
template <class T, class Alloc> bool operator> (const forward_list<T,Alloc>& first, const forward_list<T,Alloc>& second);
Parameters
first − First forward_list object.
second − Second forward_list object of same type.
Return value
Returns true if first forward_list is greater than second otherwise false.
Exceptions
This member function never throws exception.
Time complexity
Linear i.e. O(n)
Example
The following example shows the usage of std::forward_list::operator> function.
#include <iostream>
#include <forward_list>
using namespace std;
int main(void) {
forward_list<int> fl1 = {1, 2, 3, 4, 5};
forward_list<int> fl2 = {1, 2, 3, 4};
if (fl1 > fl2)
cout << "First list is greter than second." << endl;
fl1 = fl2;
if (!(fl1 > fl2))
cout << "First list is not greter than second." << endl;
return 0;
}
Let us compile and run the above program, this will produce the following result −
First list is greter than second. First list is not greter than second.
