Question :

Write a program that uses two functions to calculate area of a circle and of a rectangle. Instruction: Declare P1 as a global constant.

Use function prototype on both function.

Interactive input using loops, and the area of circle rounded to two decimal places. Function 1, calculate area of a circle and returns the values.

Example:

double circle(double r)

{

write code to return area of a circle (area is 3.14* radius squared)

} Function 2,

calculate area of a rectangle and displays the values.

Example:

void rectangle(int length, int width)

{

write code to displays area of rectangle (area is length * width)

}
