Write a program in C++ that will create two text files containing some integer numbers separated with blank spaces. The program will read the numbers from both the text files and will perform sum and product operations on these numbers. The results of theseoperations will be written to the third text file.

Answer:
C++ Programming Language
Basics
This chapter explains the features, technical details and syntaxes of the C++ programming language. I assume that you could write some simple programs. Otherwise, read "Introduction To C++ Programming for Novices and First-time Programmers".
To be a proficient programmer, you need to master two things: (1) the syntax of the programming language, and (2) the core libraries (i.e., API) associated with the language.
1. Introduction to C++
C++ Standards
C++ is standardized as ISO/IEC 14882. Currently, there are two versions:
C++98 (ISO/IEC 14882:1998): First standard version of C++.
C++03 (ISO/IEC 14882:2003): minor "bug-fix" to C++98 with no change to the language. Commonly refer to as C++98/C++03 or First C++ standard.
C++11 (ISO/IEC 14882:2011): Second standard version of C++. Informally called C++0x, as it was expected to finalize in 200x but was not released until 2011. It adds some new features to the language; more significantly, it greatly extends the C++ standard library and standard template library (STL).
C++14: Infomally called C++1y, is a small extension to C++11, with bug fixes and small improvement.
C++17: informally called C++1z.
C++2a: the next planned standard in 2020.
C++ Features
C++ is C. C++ supports (almost) all the features of C. Like C, C++ allows programmers to manage the memory directly, so as to develop efficient programs.
C++ is OO. C++ enhances the procedural-oriented C language with the object-oriented extension. The OO extension facilitates design, reuse and maintenance for complex software.
Template C++. C++ introduces generic programming, via the so-called template. You can apply the same algorithm to different data types.
STL. C++ provides a huge set of reusable standard libraries, in particular, the Standard Template Library (STL).
