In C++, variables that store floating point numbers are declared as either float or double. a. Describe floating point numbers. b. Explain the difference(s) between float or double data types. C. Let x be the first TWO digits of your matric number(group leader), y be the last TWO digits of your matric number, and define z as x. y If the first digit of y is o, replace it with 7. Example: Suppose your matric number is 2013104. Thus, x = 20, y = 74 and z = 20.74 Determine the IEEE-754 Single Precision Floating-Point Numbers of decimal value x. y. Explain each step
