Question

Declare double variables x1, y1, x2, and y2, and read each variable from input in that order. find the midpoint between point (x1, y1) and point (x2, y2) and assign the result to xmidpoint and ymidpoint.

The calculation is midpoint = (x1+x2/2) + (y1+y2/2)
Ex: If the input is 2 0 1 5 3 5 4 0 the output is
(2.75, 2.75)

Answer 1

To find the midpoint between two points (x1, y1) and (x2, y2), declare the variables, read the input, then use the formula ((x1+x2)/2, (y1+y2)/2) to calculate xmidpoint and ymidpoint.

Step-by-step explanation:

The question asks to calculate the midpoint between two points (x1, y1) and (x2, y2). The midpoint formula is ((x1+x2)/2, (y1+y2)/2).

First, declare the double variables x1, y1, x2, and y2. Then read the variables from the input. To find the midpoint, add x1 to x2, divide by 2 to get xmidpoint. Repeat this process with y1 and y2 to get ymidpoint. For example, if the input is 2, 0, 1, 5, 3, 5, 4, 0, the output should be (2.75, 2.75), which is the midpoint between the two given points.
