C Programming Fundamentals Quiz

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[]);
