#-- program to convert Fehrenheit tempreture to Celcius
#-- The formula is:
#--               celc = ((fahr - 32) * 5) / 9

print "Problem 1 starts..."

#-- prompt for a fahrenheit temprature and convert it to float
fahr = float(raw_input("Enter a temprature in Fahrentheit: "))

#--computing the celcius from the previously entered fahrenheit
celc = ((fahr - 32) * 5) / 9

#-- print the results
print "The tempreture is Celcius is:  " , celc
print "problem 1 ends......\n\n\n"
#------------------------- END OF PROBLEM 1 ------------------------

#--	A point in plane has two coordinates: x and y. 
#--	Write a program that asks the user for the coordinates of two points, 
#--	then calculates and reports the distance between the two points. 
#--	The distance between two points in the plane can be calculated by 
#--	taking the square root of the sum of squared differences in x and y.

#-- the following is the algorithm of solving the problem
#-- get the differences in x and y coordinates
#-- square the differences
#-- sum the squared differneces
#-- square root the sum of the square differences

print "Problem 2 starts...\n"

#-- prompt for the p1 coordinates
p1_x = int(raw_input("Enter x coordinate for point 1: "))
p1_y = int(raw_input("Enter y coordinate for point 1: "))

#-- prompt for the p2 coordinates
p2_x = int(raw_input("Enter x coordinate for point 2: "))
p2_y = int(raw_input("Enter y coordinate for point 2: "))

#-- get the differences in x coordinate and square it
squareSumXs = (p1_x - p2_x) ** 2 

#-- get the differences in y coordinate and square it
squareSumYs = (p1_y - p2_y) ** 2

#-- the distance is:
#--                 sqrt(squareSumX + squareSumY)
distance = (squareSumXs + squareSumYs) ** 0.5

#-- print the final result
print "The distance between  Point1(", p1_x, "," , p1_y , ") and Point2(", p2_x, "," , p2_y , ") is" , distance
