Chapter 6, Problem 6.42E

Program Plan Intro

Program Plan:

• In the program, we include the header files as needed.
• We also include cmath header file to call the square root function (sqrt()) and power function (pow())
• Function prototype will be declared.
• Declaring main() function as integer type.
• Variable declaration : x1,y1,x2,y2 are user defined numbers declared as double. Those variables are carried with the distance().
• distance_is resultant variable declared as double.
• Calling the distance() in the main().
• distance() :this function will help to find out the distance between two points (x1,y1) and (x2,y2).distance() function returns the result as a doule.
