Programming in C

3. (30 pts) Consider the following code.

struct Triangle {

float side1;

float side2;

float side3} t1, t2;

enum Boolean {FALSE, TRUE};

enum Boolean isEquilateral(struct Triangle * triangle);

a. (15 pts) Implement the function isEquilateral which returns enum value TRUE if the given triangle is equilateral and enum value FALSE otherwise. (Hint: in the real world, no two float values are exactly the same. If the difference of two float values is between -0.0001 and 0.0001, consider almostEqual and neglect the minor difference.)

b. (6 pts) Assign values of your choice to member variables of t1 to 2.5, 4.5, and 4.5, respectively.

c. (4 pts) Call the function isEquilateral on triangle t1 and capture the returned value in variable result.

d. (5 pts) Copy the content from t1 to t2 without having to individually copy each member.
