Thread: Homework: Converting Temperature (F to K)

Hey everyone! I am rushing to finish my last Cprogramming homework question. However i am not that familiar with Calling functions and i was wondering if u guys can check out my program and educate me on what errors i made. (I know I should read up on this kind of stuff but i just have no time today) So please any help would be greatly appreciated. Thanks!

Code:

#include <stdio.h>
#include <math.h>


int main (void)
{

	float a[6], b[6], p;

	FILE *input;
	FILE *output;
	input = fopen("a7q2.in","r");
	output= fopen("a7q1.out","w");
	
	a[i]=read_data(float a[i]);	  	  	  	  	  	  	  	  	  	  	  //Reading Data
	
	k[i]=temp_conv(float a[i], k[i], numbers);	  	  	  	  	  	  	  //Converting F to K
	
	print2(float a[i], k[i];								 	 	 //Printing to screen and
	
}

int read_data (float a[i])

	{
	fscanf(input,"%f",&a[i]);
	}
	
int temp_conv(float a[i], k[i], numbers)

	{
	for (i=0, i<20, i++)
		{
		
		if (i=0)
			{
			numbers=a[i]
			}
		
		else if (i>0 && i<20)
			{
			k[i]=(a[i]-32)*(5/9)+273.15
			}
	}
	
print2(float a[i], k[i])

	{
	printf("The total number of the temperatures is: %f"
		   "Temp (F)		Temp (K)"
		   "%.2f			%.2f", numbers, a[i], k[i]);
	
	fprintf(outfile,"The total number of the temperatures is: %f"
		   			"Temp (F)	 	 Temp (K)"
		   			"%.2f	 	 	 %.2f", numbers, a[i], k[i]);
	}

please retain format as much as possible

Dude - function prototypes - use them. You are not supposed to call a function before it is defined.

And be sure you use proper return types - if you don't want the function to return a value (ie, you want it to just do something and not return a value to the caller), use a void return type. Otherwise, you need to use the return statement.

You need to check out your for statements too - gotta be careful you don't type a comma instead of a semi-colon.

There is more, but this should get you started.

If you get more help than what I have given you here, you are doing well. A lot of people on here get somewhat annoyed when people want a rush fix up job on a rushed homework assignment. Maybe a poor mark would be enough motivation to start it earlier next time. That said, good luck on figuring out your bugs.
