What is the STL?

Answer Posted / saroj das ,balsore

C++ Standard Template Library

The C++ STL (Standard Template Library) is a generic
collection of class templates and algorithms that allow
programmers to easily implement standard data structures
like queues, lists, and stacks.

The C++ STL provides programmers with the following
constructs, grouped into three categories:

* Sequences
o C++ Vectors
o C++ Lists
o C++ Double-Ended Queues
* Container Adapters
o C++ Stacks
o C++ Queues
o C++ Priority Queues
* Associative Containers
o C++ Bitsets
o C++ Maps
o C++ Multimaps
o C++ Sets
o C++ Multisets

The idea behind the C++ STL is that the hard part of using
complex data structures has already been completed. If a
programmer would like to use a stack of integers, all that
she has to do is use this code:

stack<int> myStack;

With minimal effort, she can now push() and pop() integers
onto this stack. Through the magic of C++ Templates, she
could specify any data type, not just integers. The STL
Stack class will provide generic functionality of a stack,
regardless of the data in the stack.

What is a stl vector?

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
