Programming job interview questions and answers.
In this section, the programming interview questions were classified under 6 categories:
- General knowledge
- java interview questions
- python interview questions
- HTML/CSS interview questions.
- C++ interview questions.
The general knowledge questions are very necessary. A lot of people do not consider knowing them. Try and learn them because, the knowledge of those facts are very important.

9. What is the first programming language in the world?
Answer: Officially, the first programming language for a computer was Plankalkül, developed by Konrad Zuse for the Z3 between 1943 and 1945
10. Which language is the first high level language that was developed for an electronic computer and in which year?
Answer: John Mauchly’s shortcode in the year 1949.
11. What are short codes?
Answer; Short Code statements are codes that represents mathematical expressions in understandable form
12. What is the difference between short codes and machine language?
Answer: Short Code statements represents mathematical expressions in understandable form. However, the program had to be translated into machine code every time it ran, making the process much slower than running the equivalent machine code.

At this point, it is good that you know many prominent people in programming. It will be an added advantage. See other prominent people here (wikipedia)
21. Name popular IDE’s you know?
Answer: Netbeans, eclipse.
What are the meanings of the terminologies below.
22. Syntax: rules to describe how statements should be written
22. Pseudo code: Pseudo code is an informal general description of what a piece of code should or does do, written in regular English (or whatever your language is!). It is essential partway between code and human language. It uses a logical and even mathematical style to explain the purpose of a piece of code
23. IDE: This means integrated development environment. An integrated development environment (IDE), sometimes also known as an interactive development environment. It includes a source code editor, as well as tools to automate various tasks, a debugger to help you to identify and fix errors, and perhaps a compiler (see common terminology below), access to code libraries.
24. API: An API is an ‘Application Programming Interface’. They contain a set of rules through which your code can communicate with third party software or websites.
25. Algorithm – A set of logical or mathematical procedures to solve a problem
26. Compiler – This is a program which takes the code you have written and translates it into the binary ones and zeros of actual machine code.
27. Concatenation – Combining two things together, such as two lists or strings of text.
28. Control Flow – Controlling the order in which various sections of code are run or the rules by which they are repeated.
29. Dump – a list of data which is saved if a program crashes, often as a text file. It is very useful for diagnosing problems.
30. Floating point – A decimal number where the point can move, such as 1.23. The opposite is an integer, which is a whole number and cannot have a decimal place.
31. Function – a set of instructions which are written once to obtain a particular result, and can then be used whenever necessary by ‘calling’ it.
32. GUI – General User Interface, refers to ‘front end’ of a piece of software which the end user actually sees and interacts with
33. Interpreter – Some languages do not need a compiler, but instead use an ‘interpreter’ which translates to machine code as the program is run.
34. Iteration – A sequence of instructions which are repeated. For example, to perform an action for every item in a list you would ‘iterate’ over that list. Each time it is repeated is one iteration.
36. Logical Operation – The use of simple Bolean logical such as and, or and not.
37. Loop – a piece of code which keeps running until a certain condition is fulfilled – or isn’t fulfilled in the case of an ‘infinite loop’ which will crash the system running it.
