a)int a,b;
b)int b = 0;
int a = b;	
c.int a = 0;
float b = 3.5;
d.char grade = 'A';
e.char c = 1; or char = '1';   Im not sure is the book is okay with keeping the value 1 or they want what 1 is referring to.
f.int a, b, c, d, e , f;
g.string x = "This is a test.";

4(page 122)) - I am solving these problems assuming the variables already have been pre defined somewhere in the program.
a)y = 5*x+1;
b)C++ does not solve equation by default. Its a polynomial. i dont think there is a way to rewrite it and have the computer
read it without the help of a library
c)x = 5*a+4;
d.b = 0/-15;
