Imperative programming

Imperative programming is a programming paradigm that describes computation in terms of statements that changes the state of the machine. For example, the statement x = x +1 changes the state of the memory location of x by adding 1 to the existing value of x.

Procedural programming describes an imperative programming model where a program consists of one or more procedures, each of which contains statements that changes the state of the program.

Imperative programming indicates that programming language constructs are fairly close to the machine. The earliest imperative languages were the machine languages that were used to program computers.

Machines languages were hard to code and debug. Over time, high level languages were developed to make the programming process easier. For high level languages, compilers had to be developed so that it takes high level code and translate into machine code that can be executed directly on machines hardware.

All programs must eventually be executed at the machine level. Many other paradigms such as object oriented programming and functional programming were developed to make the programming process more structured and correct. However, all programs must eventually be converted into machine instructions.
