Above are my header file, code, and test code. The purpose is to, given the first name, last name, and DOB, calculate the maximum heart rate and target heart rate of an individual. I am getting an error that say "displayInfo does not take zero arguments but every time i try to put in an argument for the parameter I get "undeclared identifier" errors.

What are putting in as the arguments? It wants three ints.
pelach (1)
void heartRates::displayInfo(int hi, int lo, int y)

here you declare the "displayInfo" function which accepts three integers as parameters but in the main function you make a call for that function with zero arguments.. 

1
2
3
 
	heartRates rate("Jennifer", "Morris", 8, 4, 1988, 2010);

	rate.displayInfo();



I couldnt figure out what the 'int y' represents. but you should know..
and if you'll call the function like so :

rate.displayInfo (175, 50, 1973 )

it should work

thank you both for your help....i actually just ended up having displayInfo() accept no arguments at all....thanks again.

I thought that I had the solution, however, I have one last problem. When I run the program, the age, target heart range and maximum heart rate print out as decimals!!! i can still run the program but i get two errors in the function "set targetHeartRate(int max)" that say "double to int possible loss of data" i believe because I am multiplying by a decimal. How can I perform the same calculation and get the age, target heart range, and maximum heart rate to print as an integer to the screen?

i've tweaked it a bit in the header by changing double hi and double lo to int hi and int lo. Also, ive added int() around the calculations for hi and lo int the function definition for setTargetHeartRange() and setAge() but now i am getting some weird negative number for both values when i run the program (it is now error free according to the compiler). Im not sure if its the location of the value that is printing out instead of the value?
