Thread: program that prints two tables showing...

I don't have much experience in programming and i want to know if anyone can show how this can be done.


Implement the following two functions:

/* returns Celsius equivalent of a Fahrenheit temperature (ft) */
double celsius(double ft);

/* returns Fahrenheit equivalent of a Celsius temperature (ct) */
double fahrenheit (double ct);

Use these functions to write a program that prints two tables showing:

(a) the Fahrenheit equivalent of all Celsius temperatures from 0 to 100 degrees with increment 2.
(b) the Celsius equivalent of all Fahrenheit temperatures from 32 to 212 degrees with increment 4.

Code:

#include <stdio.h>
#include <stdlib.h>

int
main ( void )
{
int i, celsius, farenheit,

printf("\t\tFahrenheit<->Celsius Celsius<->Fahrenheit\n\n\n");



for ( i = 0; i <= 100; i += 2 )
{
farenheit = ((9.0 / 5.0) * i) + 32;
celsius = (5.0 / 9.0) * (i - 32.0);

printf ( "\t\t%3d\t - %6.2f \t%3d\t - %6.2f\n",\ i, celsius, i, farenheit );

}
return EXIT_SUCCESS;

Within your forloop just call your two functions for the farenheit and celsius. I see you still have to create those. Then either add the stepping you need or set a static variable to increment.

Then your printf statement will only need to call the functions with the stepping in place:

Code:

 
 printf ( "\t\t%3d\t - %6.2f \t%3d\t - %6.2f\n",\ i, celsius() + celStep, i, farenheit() + ftStep );

Is your real issue with how to create the function calls for these?

Sorry, I may have read to quick on your use of the stepping you need. I see you are are after to print the farenheit every 2 degrees, then display the celsius after every 4 degrees. You will then need to align your table up to match the appropriate F-degrees with the C-degrees then.

A friend helped me and we managed to do this but i don't know if it show what it should. because the windows closes. Can you all compile it and run if it opens and shows the right numbers please.

Code:

#include <stdio.h>
#include <stdlib.h>

int
main ( void )
{
int i;
float cel, farh;

printf("\t\tFahrenheit<->Celsius Celsius<->Fahrenheit\n\n\n");



for ( i = 0; i <= 100; i += 2 )
{
farh = ((9.0 / 5.0) * i) + 32;
cel = (5.0 / 9.0) * (i - 32.0);
printf ( "\t\t%3d\t - %6.2f \t%3d\t - %6.2f\n",\ 
i, cel, i, farh );
}
return 0;
}

how can i make the steps of 2 and 4 separately?
