wont add doubles from an array correctly

[ryandlich]

the debugger says it adds the rainfall correctly but it outputs 34 to the screen and i should get 33.9. Anyone have any ideas?

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

const int YEAR=8,MONTH=12;

void readData(int year[],double rain[MONTH][YEAR]);
void printData(int year[],double rain[][YEAR]);

int main(){

int year[YEAR];
double rain[MONTH][YEAR],total=0;

readData(year,rain);
printData(year,rain);

cout<<endl<<endl;
cout<<"Rainfall for "<<year[2]<<":"<<endl;
for(int month=0;month<MONTH;month++){
cout<<showpoint<<setprecision(2)<<setw(5)<<rain[month][2];}
cout<<endl;

for(int i=0;i<MONTH;i++){
total+=rain[i][2];}
cout<<"Total rainfall for "<<year[2]<<" is "<<total<<endl;

return 0;
}
//this function collects data
void readData(int year[],double rain[][YEAR]){

ifstream input;
input.open("rainfall.txt");
if(input.fail()){
cout<<"exiting program, failed to open file!"<<endl;
exit(1);}
for(int i=0;i<YEAR;i++){
input>>year[i];
for(int month=0;month<MONTH;month++){
input>>rain[month][i];}
}
input.close();
}
//this function prints data collected by previos function.
void printData(int year[],double rain[][YEAR]){

for(int i=0;i<YEAR;i++){
cout<<"Year "<<year[i]<<endl;
for(int month=0;month<MONTH;month++){
cout<<showpoint<<setprecision(2)<<setw(5)<<rain[month][i];}
cout<<endl;
}


}

You set the precision to 2 places, hence 33.9 comes out as 34. Try setprecision(3).
