having trouble w/ strings & function headers

This function:

	int getMonthTot();
	{
		printf("Enter the amount of trash in tons: \n");
		return trash;
	}

Prints "Enter the amount of trash in tons: \n" and tries to return an unexisting variable
Many other functions do the same

[gcampton]

hauler=getString();


but

char getString(hauler)

your not passing any parameters to the function which expects a something.... It's written wrong. it should be either:

char getString()

or

char getString(char hauler)

EDIT: Baz beat me to it: none of your functions are getting input, they are simply printing out a string then returning a variable which is void
Also unless you need to use character arrays you should just use std::string, much easier.(and your including string.h but not using it)

I am still having a problem that shows an error for C2447 missing function header; is there a particular header that needs to be used in this program?

[guestgulkan]

Most of those function definitions are wrong.
They look like this (Notice the incorrect semi-colon - obviously a copy and paste error):

	int getMonthTot(); //ERROR semicolon
	{
		printf("Enter the amount of trash in tons: \n");
		return trash;
	}

That is what error C2447 is warning you about.

This is the only one that is written correctly.

	char getString(hauler)
	{
		printf("Enter your company name: ");
		return hauler;
	}

[gcampton]

This is the only one that is written correctly.

	char getString(hauler)
	{
		printf("Enter your company name: ");
		return hauler;
	}

That's not correct either. It needs a name for the object hauler, or needs a type for the name hauler.eg, (char hauler) (hauler h)

As far as missing function header, you should re-paste your updated code so we can have a look at it. I'm going to take a wild stab in the dark and say you probably need to #include <iostream>

This is how I have it written now, all seems to be working except for the results. I need to print out 'if the amount of trash collected this month is less than last month, the charge is 350. per ton; but if amount is greater than the previous month prompt the user for that total. apply the excess for current month & add amount to calculated amount.

#include <stdio.h>
#include <string.h>

//FUNCTION PROTOTYPES
void getString(const char* prompt, char *buffer, int maxlength);
int getInt(const char* prompt);

int main()
{
    //DECLARE VARIABLES
    int trash=0;
    int lMTot=0;
    int monthTot=0;
	int retVal = 0;
    float rate=350.00;
    char hauler [20];

    //PRIME READ OF HAULER
    getString("Enter your company name", hauler, 19);
	while (trash != -1)
	{
		printf("Enter amount of trash in tons, or enter a -1 to quit.\n");
		trash=getInt("Enter the amount of trash in tons");
		if (trash !=-1)
			monthTot += (trash * rate);
		
	}
	printf("Your monthly total is:$ %d\n", monthTot);
    lMTot=getInt("Enter the amount from last months total in tons");
	
		while(lMTot <= trash)
		{
			if(lMTot <= trash)
				retVal = (lMTot - monthTot)*(rate);
			else
				retVal = (monthTot * rate) ;
		}
		printf("Your total amount due is:$ %f%d\n", &retVal);
		printf("Hauler name: %s owes: %d for the month\n", &hauler,&retVal);
    return 0;
}

void getString(const char* prompt, char *buffer, int maxlength)
{
    printf("%s: ", prompt);
    fgets(buffer, maxlength, stdin);
}

int getInt(const char* prompt) 
{
    int retVal;
    printf("%s: ", prompt);
    scanf("%d", &retVal);
    return retVal;
}
