Commonly used APIs in a stack

The following table shows commonly used stack APIs:

API	Description
top()	This returns the top-most value in the stack, that is, the value that was added last
push<data_type>( value )	This will push the value provided to the top of the stack
pop()	This will remove the top-most value from the stack
size()	This returns the number of values present in the stack
empty()	This returns true if the stack is empty; otherwise it returns false

#include <iostream>#include <stack>#include <iterator>#include <algorithm>using namespace std;int main ( ) {  stack<string> spoken_languages; spoken_languages.push ...
