Question

Write a program in C++ that merges the numbers in two files and writes all the numbers into a third file. Your program takes input from two different files and writes its output to a third file. Each input file contains a list of numbers of type int in sorted order from the smallest to the largest. After the program is run, the output file will contain all the numbers in the two input files in one longer list in sorted order from smallest to largest. Your program should define a function that is called with the two input-file streams and the output-file stream as three arguments. Your program needs to read input data from files merge1 and merge2 and write output to file merged

Explanation / Answer

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
int num1, num2;

ifstream inputFile;
ifstream inputFile2;
inputFile.open ("input1.txt");
inputFile2.open("input2.txt");
ofstream outputFile;
outputFile.open("output.txt");

inputFile >> num1;
inputFile2 >> num2;
while(inputFile.eof() && inputFile2.eof())
{
if (num1 < num2)
{
outputFile << num1;
inputFile >> num1;
}
else
{
outputFile << num2;
inputFile2 >> num2;
}

}

inputFile.close();
inputFile2.close();
outputFile.close();

return 0;
}
