What am I doing wrong?

I am trying to make a nested for loop to convert celsius to fahrenheit but overtime i run the code i lose the previous column. Any advices? Thanks


#include <iostream>
using namespace std;

#include <iomanip>
#include <cmath>

int celciustofarenheit (int);
int farenheittocelsius (int);
int celsius;
int column;

int main() {
cout << "Celsius" << setw (10) <<"Farenheit" << setw(10);
cout << "Celsius" << setw(10) << "Farenheit" << setw(10);
cout << "Celsius" << setw(10) << "Farenheit" << setw(10);
cout << "Celsius" << setw(10) << "Farenheit" << setw(10) << endl;


for (celsius = 0; celsius <=24; celsius ++)
{
cout << setw(7);
cout << celsius;
cout << setw(10);
cout << celciustofarenheit (celsius)<< endl;

for (celsius = 25; celsius <=50; celsius ++)
{
cout << setw(27);
cout << celsius;

cout << setw(10);
cout << celciustofarenheit (celsius) << endl;

}

}

return 0;
}

int celciustofarenheit (int)
{
return (( celsius * 9/5) + 32);
}

Write pseudocode

for each item
print 4 then go to next line

change variable for second for loop
ric717 (9)
That's kinda what I did and unfortunately is not working
integralfx (897)
Also, I would recommend to use floats not ints.

Will floats allow me to use different initial values for the same variable? Or should I just change the variable for the following loops?

I want to arrange Celsius (0-100) and it's conversion to Fahrenheit in columns of 25 outputs

Hint:

for ( int i = 0; i < 25; i++ )
{
   for (int j = 0; j < 4; j++)
      cout << i + (j * 25 );

   cout << endl;
}


Plus free giveaway for heading:

for (int i = 0; i < 4; i++)
   cout << "Celsius" << setw(10) << "Farenheit" << setw(10);

cout << endl;

Add a format flag to left-justify, tweak some of the setw()s, and you get a pretty output:

Your code kinda works. Instead of increasing from top to bottom it increases from left to right. I think i can tweak it to get the output i want.

Thank You!!!!!!!
