Hi, i need some help to make a prograsm that will read from a file and sort the numbers in lowes to highest order. For example the file will contain 5 4 3 2 1 and i want to to come out as 1 2 3 4 5 . How will i do this? I have some idea where to start from as i have made it so it loads the numbers but i dont know how to properly sort them in order. I know i need to make it so that the first number check with the second number and it flips accordingly and so on.
This si what i have so far.
//Program that demonstrates how to use input and output files
//Libraries used in the program
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <conio.h>
using namespace std;
int main()
{
//Declaration of Variable and Arrays
int Index=0;
int NumData = 1;
vector<string> Array1(NumData);
vector<string> Array2(NumData);
//Specifies the Files that are used for Input and Output
ifstream InFile1("InData.txt");
//Displays error message if File can't be opened
if (InFile1.fail())
{cout << "File could not be opened";
return(0);
}
//Loads Array from Input file - READS ENTIRE LINE
while ( getline(InFile1, Array1[Array1.size()-1]) )
{
Array1.resize(Array1.size()+1);
}
InFile1.close();
//Removes extra space at the end
Array1.resize(Array1.size()-1);
//Displays array and outputs it to outfile
ofstream OutFile ("OutData.txt");
cout << "Array: ";
for (Index = 0; Index < Array1.size(); Index++)
{
OutFile << Array1[Index]<< endl;
cout << Array1[Index]<<endl;
}
system("pause");
return(0);
}
