What did I do wrong when calling out this function

[imastruggler]

So here's my code:



#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
using namespace std;

//function prototypes
int readRainFall (ifstream& inFileName, double rainfalls[], int MONTHS);
double getrainTotal(double[], int);
double gethighestRainfall(double rainfalls[], int MONTHS);
double getlowestRainfall(double rainfalls[], int MONTHS);


int main() {


const int MONTHS = 12;

string monthName[MONTHS] = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
double rainfallAmount[MONTHS];
int count=0;
double avg;
double totalRain, mostRain, leastRain;
string name, mostMonth, leastMonth, inFileName, outFileName;


cout << "Please enter the name of output file: ";
cin>>outFileName;

//call function
readRainFall (inFile "in6s17.txt", rainfallAmount, MONTHS);//This is where I have problems!!




ofstream outFile;
cin>>outFileName;
outFile.open(outFileName);

outFile << fixed << showpoint << setprecision(1);


outFile << "YEARLY MONTHLY RAINFALL" << endl;
outFile << "Month"<<setw(20)<<"Rainfall in inches"<<endl;


for (int count = 0; count < MONTHS; count++) {
outFile << monthName[count]<<setw(17)<<rainfallAmount[count]<<endl;

}

totalRain = getrainTotal (rainfallAmount, MONTHS);
outFile << "The total rainfall for the year is "<<totalRain<<" inches."<<endl;

avg = totalRain/MONTHS;
outFile << "The average monthly rainfall is "<<avg<<" inches."<<endl;


mostRain = gethighestRainfall(rainfallAmount, MONTHS);
outFile << "The highest rainfall of "<<mostRain<<" occured in April"<<endl;

leastRain = getlowestRainfall (rainfallAmount, MONTHS);
outFile << "The lowest rainfall of "<<leastRain<<" occured in June"<<endl;
outFile << "The lowest rainfall of "<<leastRain<<" occured in July"<<endl;

outFile <<"Rainfall of 4 inches or more occured in February."<<endl;
outFile <<" "<<endl;
outFile<<"Rainfall of 4 inches or more occured in March."<<endl;
outFile << " "<<endl;
outFile << "Rainfall of 4 or more inches occured in April."<<endl;


cout << "Programmer: ";
getline(cin,name);
outFile<<name;
cout << "Processing complete"<<endl;




outFile.close();



return 0;


}


int readRainFall (ifstream& inFile, double rainfalls[], int MONTHS)
{
string inFileName;
int count=0;
cout << "Please enter the name of the input file: ";
cin>>inFileName;
inFile.open(inFileName);
if (!inFile.is_open())
{
cout << "Error opening file"<<endl;
}
else {
while(count<MONTHS && inFile >> rainfalls[count])
count++;
}
inFile.close();
return 0;


}


double getrainTotal (double rainfalls[], int MONTHS)

{
double total=0;
for ( int count = 0; count < MONTHS; count++)
total += rainfalls[count];
return total;
}

double gethighestRainfall(double rainfalls[], int MONTHS)
{
double highest;
highest = rainfalls[0];
for (int count=1; count <MONTHS; count++)
{
if (rainfalls[count] > highest)
highest = rainfalls[count];
}
return highest;

}

double getlowestRainfall(double rainfalls[], int MONTHS)

{
double lowest;
lowest = rainfalls[0];
for (int count =1; count <MONTHS; count++)
{
if (rainfalls[count]< lowest)
lowest = rainfalls[count];

}
return lowest;

}




It keeps saying stuff like "Expeceted ')' " or something else. I don't know what I'm doing wrong?

readRainFall (inFile "in6s17.txt", rainfallAmount, MONTHS);

copy-paste the error message verbatim.
If you don't understand the message, don't paraphrase it.

[nuderobmonkey]

You need to create and open an std::ifstream object and pass that th your readRainFall() function.

 ...
ifstream inFile("in6s17.txt");
readRainFall (inFile , rainfallAmount, MONTHS);
 ...

[imastruggler]

@ne55t "Expeceted ')' " is exactly what it said

@nuderobmonkey

That works, but would that count as hardcoding? (I'm not supposed to hardcode.)

[nuderobmonkey]

This was just an example. Feel free changing the 'hardcoded' string with the string variable of your choice ;-)

[imastruggler]

Does this count as not coding?

ifstream inFile(inFileName);
readRainFall (inFile, rainfallAmount, MONTHS);
