By using c++ programming

3.1 Task One Type the following code into your coding environment to verify the purposes of the functions # include 2void print_star (void) : void main (void) 3 void print-message (void); 5 print star print message O print star 10 void print star (void) 11 E 12 13 14 void print message (void) 15 16 17 printf(" How do you don") Question: 1) What is the output of the program when execute it? 2) What are the purposes of line 2-3? 3) Summarize the steps of using user-defined functions in C 3.2 Task Two The following program two values entered by user. You are asked to complete the code finds the max number between #include-stdio.h> int max (int int); void main void) int a, b,c printf( Please input two integer values:"); c- max(a,b); printf(the max number you entered is %dn", c); return 0; // define function here int z; if (xyz-X;) elsez-y) return Questions 1) How function gets information from the main function who calls it? 2) Does the function change the value that is passed to it? 3.3 Task Three Write a program to calculate the distance between two points A(xl,yl) and B(x2,y2), where xl, yl, x2, y2 are read from a file. The calculation should be done by calling a function named distance. This function takes four arguments (xl, yl, x2, and y2) and returns the value of the distance between the two points
