QUESTION 1 Write a complete program that consists of the main function that will call 4 user-defined functions. The task of each function is described below. 1. The first function is to display your information such as: Full Name Matrix No Group 2. The second function is to display a Plagiarism Declaration statement "I confirm that this LAB TEST is my own work and is not copied fror a. b. C. 3. The third and the fourth functions are based on the following problem Sound travels through the air because of collisions between the molecules in the air. The temperature of the air affects the speed of the molecules, which in turn affects the speed of sound. The velocity of sound in dry air can be approximated by the formula: Velocity = 331.3 + 0.61 × Tc Write a function that allows the user to input a starting and an ending temperature. Within this temperature range, another function pass by value should output the temperature and the corresponding velocity in 1° increments using a do-while loop. For example, if the user entered 0 as the start temperature and 2 as the end temperature, then the program should output: At 0-degree Celsius the velocity of sound is 331.3 m/s At 1-degree Celsius the velocity of sound is 331.9 m/s At 2-degree Celsius the velocity of sound is 332.5 m/s Figure 1: Sample output display Global variables are not allowed to be used in your program. You can be creative to display the output program and not limited to above Figure 1. Your program should allow the user to repeat the process as often as the user wishes until he/she wants to exit the program.
