Answer the following:
(a) Give four examples of programming languages.
(b) Write the full form of the following:
IDE
BASIC
BEDMAS
(c) What is the use of the END statement in QBasic?
(d) What is debugging?
(e) Which statement in QBasic is not executed and ignored?
(f) Which relational operator is used to check equality?
(g) Which function key is used to run a program in QBasic?
Write True or False:
(a) Computer is an electronic device.
(b) Pen drive is an input device used to enter data.
(c) The person who uses a computer is called a programmer.
Answer (2)
The answer covers examples of programming languages, full forms of acronyms, the function of the END statement in QBasic, the meaning of debugging, which QBasic statement is ignored, the equality operator, and the F5 key usage. It also includes True or False statements regarding definitions related to computers. Overall, the response provides foundational knowledge relevant to programming and computer usage.
;
(a) Four examples of programming languages are:
Python
Java
C++
JavaScript
(b) The full forms of the given abbreviations are:
IDE: Integrated Development Environment
BASIC: Beginners' All-purpose Symbolic Instruction Code
BEDMAS: Bracket, Exponent, Division, Multiplication, Addition, Subtraction
(c) In QBasic, the END statement is used to indicate the end of a program. It tells the computer to stop executing the program when this statement is reached.
(d) Debugging is the process of finding and fixing errors or bugs in a computer program. Programmers use debugging techniques to ensure that their programs run as intended without errors.
(e) In QBasic, comments are not executed and are ignored by the compiler. Comments usually start with the REM keyword or a single quote ('). They are used to explain the code to humans and provide additional context.
(f) The relational operator used to check equality is =.
(g) In QBasic, the function key F5 is commonly used to run a program.
Write True or False: (a) True: A computer is an electronic device. (b) False: A pen drive is a storage device, not an input device. It is used to store and transfer data. (c) False: A person who uses a computer for general use is called a user. A programmer is specifically someone who writes computer programs.
