Hi,
The problem is that I have a program which processes a 2D array. One task is to find the min and max of one column (ignoring the second). Here is my code so far:
The last lines are faulty. Any ideas?Code:#include <iostream.h> #include <stdlib.h> #include <fstream> using namespace std; double data[4][2]; // declare 2D array for data in file. int count; int noOfReadings; int counter=0; int numberOfSpeedIntervals; int numberOfSectors; int main() { ifstream inPutFile;//Creates stream to input file. inPutFile.open("c:\\grade.txt");//Opens stated file. if (!inPutFile)//Deals with problems opening file. cout << "Error opening file!" << endl; //Finds how many lines of data there are. int item; while (!inPutFile.eof()) { inPutFile >> item; counter++; } const int rows = (counter/2); cout<<"Number of rows: "<<rows<<endl; cout<<"Please type how many intervals do you require: "; cin>> numberOfSpeedIntervals; cout<<"Please type how many sectors do you require: "; cin>> numberOfSectors; //initialise current max and min // find max and min // initialise current max and min double maxRead = data[i][0]; double minRead = data[i][0]; for (int i = 1; i < data; i++) { if (maxRead < data[i]) { maxRead = data[i]; } if (minRead > data[i]) { minRead = data[i]; } } system("PAUSE"); return 0; }
Will
