Hi, I just got this assignment and am struggling a little bit. I am getting multiple errors. The errors are:
Line
Error 1 error C2660: 'calcAmph' : function does not take 2 arguments 27
Error 2 error C2660: 'calcMam' : function does not take 2 arguments 31
Error 3 error C2660: 'calRep' : function does not take 2 arguments 35
Error 4 error C2082: redefinition of formal parameter 'height' 73
Error 5 error C2082: redefinition of formal parameter 'age' 73
Error 6 error C2082: redefinition of formal parameter 'height' 97
Error 7 error C2082: redefinition of formal parameter 'age' 97
Error 8 error C2082: redefinition of formal parameter 'height' 121
IntelliSense: too few arguments in function call 27
IntelliSense: too few arguments in function call 31
The purpose of this program is to determine the amount of food eaten by a certain kind of animal. Rather than using one big pile of main( ), you need to use functions for these calculation that incorporate pass-by-value parameters. In addition, you need to include various int or double const declarations within your program. Finally, embed your program in a loop so that the calculation can be repeated as often as the user wishes.
IN ORDER TO RECEIVE FULL CREDIT, YOU MUST DEFINE AND CALL FUNCTIONS AND PASS ARGUMENTS.
You should base your calculations on the following table:
Mammals
1 lb for each 10 lbs in weight
1/3 lb for each foot in height
1/10 lb for each 5 years of age
Add an extra 15% of food if the animal can run faster than a human
Amphibians
2/3 lb for each 5 lbs in weight
1/4 lb for each 6 inches in length
1/5 lb for each 4 years in age
Add an extra 10% of food if the animal is pregnant
Reptiles
1/5 lb for each 6 lbs in weight
1/2 lb for each foot in length
Deduct 10% of food during winter
What I have so far is:
