What is the output of the following code snippet?
float PerHeight = 178.89;
if (PerHeight < 150.0)
printf("The person is Dwarf. \n");
else if ((PerHeight >= 150.0) && (PerHeight < 165.0))
printf("The person is average heighted. \n");
else if ((PerHeight >= 165.0) && (PerHeight <= 195.0))
printf("The person is taller. \n");
else
