Four data files (CAR1.DAT, CAR2.DAT, CAR3.DAT and CAR4.DAT ) are available in Blackboard in the assignment folder. Each file contains track results with the following format:

The test vehicle number (line 1).

The test date (line 2).

The test driver (line 3).

Time, t, in seconds and distance, x, in feet (one pair of (t,x) values per line for all other lines)

Velocity can be defined as v = dx/dt and acceleration can be defined as a = dv/dt. Theses equations can be approximated by v = change in distance/change in time and a= change in velocity/change in time . For the data provided above, assume v = 0 and a = 0 at the first time value 0.0. Using the above approximations v1 = (5.5 0.0)/(0.2 0.0) = 5.5 ft/0.2 s = 27.5 ft/s and a1 =( 27.5 0.)0 / ( 0.2 0.0) = (27.5 ft/s)/0.2 s = 137.5 ft / s² . The remaining values can be determined in a similar manner.

Program Requirements:

Write a C++ program that will accomplish the following:

The program should ask the user which data file is to be used. Read the filename as a string and open the file using a string variable. Do not use an array.

Calculate the velocity and acceleration. The output of the result should be sent to a data file. The name is specified by the user. The output includes

test vehicle number

test date

test driver

values for time, distance, velocity (ft/s) and acceleration (ft/s²) for each of the data points in the input data files ( 4 numbers per line)

send the values to a commas delimited file

open the file in Excel, graph time vs. acceleration and time vs. velocity
