Programming Logic and Design

What is programming?

The process of designing and building executable computer software to accomplish a specific task.

What is an algorithm?

A step-by-step procedure for solving a problem.

What is pseudocode?

A method of planning a program using human-readable instructions that resemble programming code.

What is the main function of a programming language?

To create instructions that a computer can understand and execute.

What are the three basic steps involved in problem-solving using programming?

1. Input: Gather data. 2. Process: Perform calculations or operations. 3. Output: Display results.

What is a flowchart?

A diagram that visually represents the sequence of steps in a program or process.

What is a variable?

A storage location identified by a name that can hold different values during the execution of a program.

What is the difference between a variable and a constant?

A variable's value can change, while a constant's value remains fixed throughout the program.

What are the most common data types used in programming?

Integers, floating-point numbers, characters, strings, and booleans.

What is type casting?

Converting one data type into another (e.g., from int to double).

What is an escape sequence?

A special character that starts with a backslash (") and represents something other than a literal character.

What does the else statement do in a conditional structure?

Defines the block of code to execute if the if condition is false.

What is the syntax for a for loop in C++?

for(initialization; condition; increment/decrement) { // Loop body }

What is function overloading?

Defining multiple functions with the same name but different parameter lists.

What is the difference between a local variable and a global variable?

A local variable is declared inside a function and can only be accessed within that function. A global variable is declared outside any function and can be accessed anywhere in the program.

What is recursion in programming?

Recursion is when a function calls itself in order to solve a problem.

What is the significance of void as a return type for functions?

void means that the function does not return any value.
