Calculate the value of the following expressions with int a = -4; int b = 7; float c = 4.2; float d = 0.0; and char g = ‘g’. solve these questions by using these values.(e. g. a*c the result will be -16.8 and it is a float number)

a. a / b * g
b. (a + g) / a * d
c. (b - a) / g + d
d. (a + g) * (d + g)
e. (g – c) – b + a * g
