easy if you know how to use functions...

sorry guys...it's been awhile....i can't figure out how to link these functions together....our teacher doesn't want use to put anything in main that has to do with the program......i might have a lot wrong w/ it syntatically and logically...if anyone can help me in anyway it'd be very helpful.....here's the code i have so far...

I think your teacher means: don't put the content of what could be in functions into the main.

But the main sure needs to contain the functions, since in this way it doesn't do anything.

A hint: try to find out what the functions actually do and create a flow chart where you use the functions as black boxes. This flow chart can be implemented in the main.

k, i'll definitely try that and get back to u....

These are all because when you declared the functions, you wrote them with 5-6 parameters, but when you called them from main, you only passed them three.

just a quick hint on functions

C:\Temp\lab1.c(35) : error C2198: 'devils' : too few actual parameters

prototype/* devils(int i, char j, char *str);
has args of the integer type a
& a char type also a char type string;


func call /* devils(6, ch, name);
when called pass values that need to be processed by the declaration;



declaration /* devils(int i, char j, char *str);
here is where the values get processed/manipulated;

hope i helps

You have design problems with your code.....
look at this function ( the others are the same i just picked this one)

Code:

---

int skydive(int x, int y, int z, int base, int lodge, int inn, int day1, int
day2, int total)
{


printf("How many people are going on the trip?");
scanf("%d", &x);
printf("\nHow many people are going to be staying in the Wilderness Lodge?");
scanf("%d", &y);
printf("\nHow many people will be staying at the Luxury Inn?");
scanf("%d", &z);
printf("\nHow many days?");
scanf("%d", day1);
printf("How many days?");
scanf("%d", day2);
base = (x * 400);
lodge = (y * 65 * day1);
inn = (x * 120 * day2);
total = (base + lodge + inn);

printf("\n People going on trip: %d", x);
printf("\n Peope staying at the Lodge: %d", y);
printf("\n Peope staying at the Inn: %d", z);
printf("\n How many days: %d", day1);
printf("Base price: %d", base);
printf("\n Lodge price: %d", lodge);
printf("\n Inn price: %d", inn);
printf("\n Total price: %d", total);
}

---

For a start you pass in parameters x,y,z,day1 and day2. You then immediately write over whatever you passed in because those variables are used immediately in scanf() statements. That means they do not have to be passed in at all and instead should be local variables to the function. You have done the same thing everywhere. All this does is make your code confusing. Try going through it and reordering the code a little.You will find it much easier to see whats going on then.
