Introduction to C++ Programming Language

Introduction to C++ Programming Language   C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation. It was designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency and flexibility of use as its design highlights. C++ has also been found useful in many other contexts, with key strengths being software infrastructure and resource-constrained applications,including desktop applications, servers (e.g. e-commerce, web search or SQL servers), and performance-critical applications (e.g. telephone switches or space probes).C++ is a compiled language, with implementations of it available on many platforms. Many vendors provide C++ compilers, including the Free Software Foundation, Microsoft, Intel, and IBM. C++ is standardized by the International Organization for Standardization (IS...

The Assembly Process Of 8086 Microprocessor Assembler Assembler is a translator which converts Assembly language into object file (Machine Codes ) It translate each of the instruction to its corresponding object code line by line Assembling Steps Two Pass Assembling Steps Two Pass Assembling means that the assembler passes  through the source code two times Step1: On First Pass             Assembler Look for the labels and defintions and pass them into the symbol table for later use             after assigning memory address to the labels Step2: On Second Pass            Normal translation of source code into object code occurs
