Program | MCQs

Explanation

In C programming, && is the logical AND operator, used to evaluate whether both conditions are true.

It differs from &, which is a bitwise AND operator.

Explanation

In C language, each statement ends with a semicolon (;) to indicate the end of an instruction.

This helps the compiler understand where one statement ends and the next begins.

Explanation

The break statement, when used inside a loop, immediately exits the loop and transfers control to the statement following the loop.

It does not terminate the entire program, only the current loop.

Explanation

Low-level languages (like assembly language) are close to machine code and require deep understanding of hardware structure.

They offer more control over hardware but are complex and hardware-specific.

Explanation

The Halting problem is about determining whether a given program will terminate (halt) or run indefinitely for a specific input.

It was proven by Alan Turing that there is no general algorithm to solve this problem for all possible programs.

Explanation

In flowcharts, a parallelogram is used to show input (e.g., user enters data) or output (e.g., display result) operations.

It helps distinguish between data flow and processing steps in a program’s logic.

Explanation

In Scratch programming, an event is something like clicking a sprite or pressing a key, and the program responds to it by running certain code.

Events help make Scratch projects interactive and dynamic.

Explanation

The continue statement is the opposite of the break statement; it skips the current iteration and moves to the next one in a loop.

It's also called the bypass statement because it bypasses part of the loop code.

Explanation

In assembly language, mnemonics are symbolic names (like MOV, ADD, SUB) used instead of binary code to represent instructions.

They make programming easier and more readable for humans.

Explanation

Nested loops are loops placed inside another loop.

It allowing complex iteration through multi-dimensional data structures.

They are commonly used for tasks like processing matrices or multi-level data.
