This document outlines practice questions from chapters 1 and 2, including writing a function to display a character 40 times, writing a function to display a string a specified number of times, using nested for loops to print a triangular pattern, writing a program to calculate triangular numbers from user input, and writing a program to check if a user input number is even or odd.

1. In this session, you will do the practice questions of Chapter 1 and Chapter 2. Objectives

2. Write a function to accept a character and display it 40 times. Write a function that accepts a number from 0 to 9, along with a string. The string should then be displayed the number of times specified. Chapter 1

3. 1. Write a for loop, which will produce the following output (Hint: use two nested for loops): 1 22 333 4444 55555 Create a C program, which calculates the triangular number of the user’s request, read from the keyboard using scanf(). A triangular number is the sum of the preceding numbers, so the triangular number 7 has the value of 7+6+5+4+3+2+1 (same as a factorial in mathematics, for example, factorial of 7 ---- !7). Chapter 2

4. Create a C program to check whether the number entered by user is even or odd. Chapter 2
