How program execute?

1. The final product of the compilation process （广义的编译，包括预处理、编译、汇编和链接） is an executable program, which consists of a set of machine language instructions.
2. When you start a program, the operating system loads these instructions into the computer's memory so that each instructon has a particular memory address.
3. The computer then goes through these instructions step-by-step. Sometimes, as when you have a loop or a branching statement, program execution skips over instructions, jumping backward or forward to a particular address.
