file processing & for loop guestions

tcepeda (2)
after reading scores from file I need to find the lowest score, add all scores together, calculate final score, inside the for loop. I am lost and could use some help. Here is my code so far.


for (index = 1; index < 6; index++)
{
//Get score from input file
fin2 >> scores;

//Output score to outfile, fout
fout << "Score #" << index << ":" << setw(10) << scores << endl;

if (scores < lowScore)
{
lowScore = scores;
}

}

//Calculate scores total
scores += scores;

//Subtract lowest score from scores total
total = scores - lowScore;

//Calculate final score
finalScore = total / (5 - 1);



//Move read pointer
fin2.ignore(100, '\n');

//Get name from input file
getline(fin2, name, '#');

}

Here is help for you

#include <iostream>
#include <fstream>

using namespace std;

void readScores(float scores[], int &size) {
ifstream in;
float score;
size = 0;
in.open("/home/zamuxolo/qt/lowest/scores.txt");

if(!in)
cout << "File could not be opened or it does not exits." <<endl;
else {
while(in >> score) {
scores[size++] = score;
}
}

}
float sumOfScores(const float scores[], int size) {

float sum = 0.0;

for(int i = 0; i < size ; i++)
sum += scores[i];

return sum;
}
void lowestscore(const float scores[], int size) {

float lowest = 10000;

for(int i = 0; i < size; i++) {
if(scores[i] < lowest) {
lowest = scores[i];
}
}
cout << "Lowest = " << lowest << endl;
}

int main() {

int s = 0;
float scores[100];

readScores(scores, s);
cout << "Final score = "<< sumOfScores(scores, s) << endl;
lowestscore(scores, s);

}

Hope this helps.
