Introduction to STL
STL (Standard Template Library) is a set of functions and classes (types of objects.’ll Deeper lectures explained later) to reduce the work in programming. Let’s deal with one of the most used types STL, vectors.

Problem 1: When executing a program from the IDE, the console window blinks and then closes immediately.
Answer 1: Some compilers (eg. Bloodshed’s Dev C++) don’t automatically pause the console screen after the program has finished executing. If this is the case with your compiler, the following two steps will fix your problem:

A computer program is a sequence of instructions that tell the computer what to do.
Statements and expressions
The most common type of instruction in a program is the statement. A statement in C++ is the smallest independent unit in the language. In human language, it is analogous to a sentence. We write sentences in order to convey an idea

A build configuration (also called a build target) is a collection of project settings that determines how your IDE will build your project. The build configuration typically includes things like what the executable will be named, what directory the executable will be output in, what directories the IDE will look in for other code and header files, whether to keep or exclude debugging information, and how highly to have the compiler optimize your program. Generally, you will want to leave the settings at their default values unless you have a specific reason to change something.

The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a nullcharacter ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.
The following declaration and initialization create a string consisting of the word “Hello”. To hold the null character at the end of the array, the size of the character array containing the string is one more than the number of characters in the word “Hello.”

C++ pointers are easy and fun to learn. Some C++ tasks are performed more easily with pointers, and other C++ tasks, such as dynamic memory allocation, cannot be performed without them.
As you know every variable is a memory location and every memory location has its address defined which can be accessed using ampersand (&) operator which denotes an address in memory. Consider the following which will print the address of the variables defined:

References are often confused with pointers but three major differences between references and pointers are:
  • You cannot have NULL references. You must always be able to assume that a reference is connected to a legitimate piece of storage.
  • Once a reference is initialized to an object, it cannot be changed to refer to another object. Pointers can be pointed to another object at any time.
  • A reference must be initialized when it is created. Pointers can be initialized at any time.

The C++ standard library does not provide a proper date type. C++ inherits the structs and functions for date and time manipulation from C. To access date and time related functions and structures, you would need to include <ctime> header file in your C++ program.

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming.

Hello, I am talking about my work as you can learn c ++ or a programming language! I began to learn c ++ aged 13 years old and now I’m a good student and I work with this profession, if you want to achieve this I have achieved in you have to use your mind as best as possible, so if you want to learn c ++ or any other programming language you can learn online or courses, we see the days of the Internet has become more attractive so you can reach very far if it is your dream for the future.

Algorithm in mathematics and computing, is a strictly defined action for solving a problem or a certain type of problems. The algorithm can be defined as a performance that allows to obtain a given result of pursuing, in a specified order, a set of simple steps that correspond to the actions selected from a limited whole.

Algorithm Algorithm  is a process or a series of steps to be followed to solve a problem. STL provides us with a set of algorithms available in the form of functions. These algorithms allow us to manipulate containers through the iterator.
Let’s see an example of the use of algorithms

With iterator can pass on the elements of a sequence one by one. In addition, significant parts of the STL require iterator. Many functions of the STL containers and algorithms take iterator as arguments.
