Question

Can someone help me write the correct logic statements so that I can
output the name and three decimal numbers in ascending order?

Thank you.

Here is the code:


#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>

using namespace std;

int main()
{
double num1, num2, num3;
string fName, lName;
ifstream inFile;
ofstream outFile;

cout << " **Program outputs your full name and some numbers in ascending order. All input "
<< "read from a file.!**";
cout << " ";
cout << endl;

inFile.open("data.txt"); // open the input file
//check to make sure it's ok!
if (!inFile)
{
cout << " Cannot open the input file. Something is wrong!**";
cout << " The program terminates.** " << endl;
cout << " " << endl;

system("pause");
return 1;
}

outFile.open("results.txt"); //open the output file

cout << " Processing data...";
inFile >> fName >> lName;

cout << " Processing data...";
inFile >> num1 >> num2 >> num3;


//output full name to a file

outFile << fName << " " << lName << endl;
// begin conditionals to order numbers in ascending order

if (num1 < num3) // num1 less than num3
{ outFile << fixed << showpoint << setprecision(2) << num1 << ", ";

if (num3 < num2) // compare num2 and num3
outFile << fixed << showpoint << setprecision(2) << num3 << ", " << num2 << endl;
else
outFile << fixed << showpoint << setprecision(2) << num2 << ", " << num3 << endl;
}// end inner-if
}
else
{
outFile << fixed << showpoint << setprecision(2) << num3 << ", " << endl;

if (num1 < num2)
outFile << fixed << showpoint << setprecision(2) << num1 << ", " << fixed << showpoint << setprecision(2) << num2 << endl;
else
outFile << fixed << showpoint << setprecision(2) << num2 << ", " << fixed << showpoint << setprecision(2) << num1 << endl;
}

{
if (num2 < num3)
outFile << fixed << showpoint << setprecision(2) << num2 << ", " << endl;

if (num1 < num3)
outFile << fixed << showpoint << setprecision(2) << num1 << ", " << fixed << showpoint << setprecision(2) << num3 << endl;
else
outFile << fixed << showpoint << setprecision(2) << num3 << ", " << fixed << showpoint << setprecision(2) << num1 << endl;
}
else
{
if (num1 < num2)
outFile << fixed << showpoint << setprecision(2) << num1 << ", " << fixed << showpoint << setprecision(2) << num3 << endl;
else
outFile << fixed << showpoint << setprecision(2) << num2 << ", " << fixed << showpoint << setprecision(2) << num1 << endl;

*/

inFile.close();
outFile.close();

system("pause");
return 0;
}

Explanation / Answer

Mate, nested if expression is a really messy way of coding often, usually try to use "else if(condition)" If u want to print out 3 decimal number in ascending order, why don't sort just sort them? Take a look on this code. We use insertion sort function to sort numbers in ascending order. And we print them both to out file and stdout. Ask if u have any questions: #include #include #include #include using namespace std; void insertionSort(double* array, int size) { int key; int j; for (int i = 1; i = 0 && array[j] > key) { array[j+1] = array[j]; j--; } array[j+1] = key; } } int main() { double array[3]; string fName, lName; ifstream inFile; ofstream outFile; cout
