    Unhappy 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!

    #include <stdio.h>
    #include <math.h>
    int main (void)
    	float a[6], b[6], p;
    	FILE *input;
    	FILE *output;
    	input = fopen("","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])
    int temp_conv(float a[i], k[i], numbers)
    	for (i=0, i<20, i++)
    		if (i=0)
    		else if (i>0 && i<20)
    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.
