Suppose one needs an if statement to check whether an integer variable pitch is equal to 440 (which is the frequency of the note "A" to which strings and orchestras tune).Which condition is correct?
A)if (pitch - 440 = 0)
B)if ((pitch !< 440) && (pitch !> 440))
C)if (pitch = 440)
D)if (pitch == 440)
