Hello, could you mind help me a problem about C++ programming?

Design, write and debug a program that finds the change in length of a rectangular metal bar by declaring the following double variables and assigning the values shown:
F is 4. N
len is 3. m
wid is 4. cm
dep is 2. mm
e is 6.8950e4 N/(mm)^2 (aluminum)
delta_len is ? m
The equation is: delta_len = F*len/(wid*dep*e).
