Copy the value of a double variable z to the nearest integer into an int variable x.

***Microsoft Visual Studios (C++)***   Write a program that given two coordinate pairs and a third single coordinate will linearly interpolate or extrapolate the third second coordinate. For example, let's say at 50 degrees Celsius the length of a metal rod is 5.4 cm and at 60 degrees Celsius the length is 5.5cm. I can interpolate the length at 53 degrees Celsius by doing 5.4cm + 3*(.1/10)=5.43cm. Your program does not need to continuously run, but should prompt the user for two coordinate pairs, the third first coordinate and return the extrapolated or interpolated third second coordinate.

[Python Language]   A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.

Q. Given two matrices, Write a function to check whether the two matrices are identical or not. if all the elements in the respective positions of the two matrices are same, then say that they are identical and if not same then say that they are not identical. Write a program in c++ for this problem statement.
