Write a makefile to compile all programs and create an executable called Lab7. The source programs are called Term.h, Term.cpp, and Lab7.cpp. Documentation is required. This includes header comments as well as inline comments in all methods. Every right curly brace must have a comment. Programs that do not compile on the CS Linux machines with g++ will receive a grade of zero. I do not discourage students from working at home on other platforms. However, you must upload your programs to a Linux machine and compile them before you submit. The Tem class represents a term in a polynomial such as 2x4 or 9x2. For the purpose of this assignment: Adding Terms can only be done if the exponents are the same. ax bx(a+b)x Subtracting Terms can only be done if the exponents are the same. ax" bx" (a-b) x the exponents aren't the same, the addition and subtraction operators should return a Term with 0 as the coefficient and 0 as the exponent. Multiplication ax" * bx" = (a*b) x (mm) Output a term in the customary format, using A to indicate the exponent (instead of a superscript). 2x 4or9x2
