Study Notes
Introduction to C++
- Algorithm: a set of well-defined steps to perform a task or solve a problem, with an emphasis on order and sequential execution.
C++ Program Compilation
- To create an executable file from a high-level program: • Create a source file containing program statements using a text editor. • Run the preprocessor to convert source file directives to source code program statements. • Run the compiler to convert source program statements into machine instructions (machine code), stored in an object file. • Run the linker to connect hardware-specific library code to machine instructions, producing an executable file.
- Errors at any step will prevent the execution of following steps.
- Modern software development systems often provide an integrated development environment (IDE) that combines these steps.
Language Classification
- Low-level languages: used for direct communication with computer hardware, but difficult for humans to read.
- High-level languages: closer to human language, used for programming.
