Programming Languages | MCQs

Explanation

In both C and C++ programming languages, the symbol used to access the value stored at a memory address (dereferencing a pointer) is the asterisk (*).

* and & are the operators used in pointers.

* gives us the value stored at a particular address

whereas “ & “ gives us the address of the variable

Explanation

Binary is a system by which numbers, letters and other information are represented using only two symbols, or binary digits

Explanation

Machine language, or machine code, is a low-level language comprised of binary digits (1 and 2).

Since computers are digital devices, they only recognize binary data.

Explanation

Assembly language is a low-level language that uses mnemonics to represent machine-level instructions.

It is hardware-specific and closer to binary code, offering more control over hardware.

Explanation

Business refers to organizational/commercial activities, not a programming structure.

Common Programming Concepts:

Condition: Used for decision-making (e.g., if-else statements).

Sequence: The order in which instructions are executed.

Loop: Repeats a block of code (e.g., for, while loops).

Explanation

Integer data type stores whole numbers without decimals, ideal for values like 67, 100, etc.

It supports a range that easily includes numbers greater than 66.000 and doesn’t require decimal precision like float.

Explanation

In C++, the body of a function is enclosed within curly braces: {}.

This structure contains the instructions that will be executed when the function is called. 

Explanation

The basic language of a computer consists of opcode and operand.

The opcode specifies the operation to be performed, while the operand indicates the data or address involved in the operation.
