How do I get the output of this code to output to a text file instead of the .ex

Question

How do I get the output of this code to output to a text file instead of the .exe screen in the compiler?

#include<iostream>
using namespace std;

//this is function for binary
void getbinj(int nnm)
{
int rmd;

if (nnm <= 1)
{
cout << nnm;
return;
}
rmd = nnm % 2;
getbinj(nnm / 2);
cout << rmd;
}


//this is function for Hexa
void getHexa(int nnnm){
int quo = nnnm;
int oo=1,jooo,too;

char hcdm[100];

while(quo!=0) //iteratoing over the loop.
{
too = quo % 16;

if( too < 10)
too =too + 48;
else
too = too + 55;

hcdm[oo++]= too;
quo = quo / 16;
}
for(jooo = oo -1 ;jooo> 0;jooo--)
cout<<hcdm[jooo];
cout<<endl;
}

//main function
int main()
{
   //variables declaration for
int dcm, getbin;
cout << "Decimal "<<"Binary "<<"HexaDecimal";
cout<<" ";
cin >> dcm;
cout<<" ";

  
getbinj(dcm);//function call
cout<<" ";
getHexa(dcm);//function call
cout << endl;
  
return 0;
}

Explanation / Answer

#include<iostream>

using namespace std;

#include <fstream>

ofstream outputFile;

//this is function for binary

void getbinj(int nnm)

{

int rmd;

if (nnm <= 1)

{

outputFile << nnm;

return;

}

rmd = nnm % 2;

getbinj(nnm / 2);

outputFile << rmd;

}

//this is function for Hexa

void getHexa(int nnnm){

int quo = nnnm;

int oo=1,jooo,too;

char hcdm[100];

while(quo!=0) //iteratoing over the loop.

{

too = quo % 16;

if( too < 10)

too =too + 48;

else

too = too + 55;

hcdm[oo++]= too;

quo = quo / 16;

}

for(jooo = oo -1 ;jooo> 0;jooo--)

outputFile<<hcdm[jooo];

outputFile<<endl;

}

//main function

int main()

{

outputFile.open("output.txt");

//variables declaration for

int dcm, getbin;

outputFile << "Decimal "<<"Binary "<<"HexaDecimal";

outputFile<<" ";

cin >> dcm;

outputFile<<" ";

getbinj(dcm);//function call

outputFile<<" ";

getHexa(dcm);//function call

outputFile << endl;

outputFile.close();

return 0;

}
