C Programming Fundamentals Quiz

Study Notes

Character Set in 'C' Language

The 'C' language character set includes letters (both uppercase and lowercase), digits, and special characters (like punctuation and whitespace).

Definition of an Algorithm

An algorithm is a step-by-step procedure or formula for solving a problem or completing a task, presented in a logical order.

Purpose of the 'break' Statement

The 'break' statement in 'C' programming is used to exit from loops (for, while, do-while) or switch statements, providing a mechanism to alter the flow of execution.

Call by Value vs. Call by Reference

Call by value passes a copy of the variable's value to functions, preventing modifications to the original variable.
Call by reference passes the variable's actual memory address, allowing functions to modify the original variable directly.

Purpose of the 'printf()' Function

The 'printf()' function is utilized to output formatted text to the standard output, typically the console.

Syntax for the 'printf()' Function

The correct syntax to print an integer variable 'num' is: printf("%d", num);

Declaring a Recursive Function

A recursive function named 'factorial' can be declared as:

int factorial(int n);

Additional Facts about the 'break' Statement

The 'break' statement can also be used to terminate the execution of a nested loop, affecting only the innermost loop.

Purpose of the 'do-while' Loop

The 'do-while' loop guarantees that the block of code will execute at least once, as the condition is evaluated after the loop body.

Syntax for Passing an Array by Reference

To pass an array 'arr' to a function 'modifyArray' by reference, the syntax is:

void modifyArray(int arr[]);
