I figured out where my problem is but I need help correcting it. For some reason my distance formula is not working out. It should work out that the two smallest distances should equal the bigger...

I did not think indention would make a difference when it runs. I tried it anyways and it did not work.

I am making a martian leap year program(pointless program for class). This is the given :

1) All odd years are leap years.
2) All years divisible by 8, but not by 32 are leap years. (Thus, 8, 16...

The if- statements are still not working. This is what I have:



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

int main() {

int x1,x2,x3,y1,y2,y3,a1,a2,a3,a4,a5,a6;

tried that after I posted. Still same result

For some reason I can not get the if statements at the end to work. Atleast one of the if statements should work during each run of the program. Thanks in advance.




#include <stdio.h>...

Thanks for catching that. I am using Jgrasp with GCC.

I fixed that problem and the output is still incorrect. For c12 I get the correct answer but for c13 and c14 I am getting 1627902208.00.




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

int main() {

Why are the last two equations printing the wrong numbers? Thanks in advance.




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

int main() {

Sorry I forgot a a period in the print function at the bottom. The corrcted one and still not working:



#include <stdio.h>

int main(){

float distance, speed1, speed2, minutes, mainrate,...

This is what I need to write: Imagine a two-way straight railway and two trains approaching each other from opposite directions. You need to compute how long (in minutes) would it take for these...

Please Help.

int main()
{
int index, points[6];
char input[250], output[250];
FILE *ifp, *ofp;

printf("Which file would you like to read from?\n");
scanf("%s", input);

fixed...


int main()
{
int index, points[6];
char input[250], output[250];
FILE *ifp, *ofp;

printf("Which file would you like to read from?\n");

Thanks so much, now that part works. You will hear more from me in other threads. I still have a lot to go :) haha

I think I might have got it... Does this make any sense?



int main()
{
int index, points[6];
char *input, *output, a, b;
FILE *ifp;

I really did'nt understand the FAQ at all. I cleaned up the code a bit...



int main()
{
int index, points[6];
char *input, *output;
FILE *ifp;

Sorry did'nt see you posted a FAQ. I will read that over.

Im sorry I am real new to pointers. Can you please explain too me how I would point to something and why? Thank you in advance for the help.

Please any advice??? It is due tonight

int main()
{
int index, points[6];
char *input, *output;
FILE *ifp;

printf("Which file would you like to read from?\n");
scanf("%s", input);

printf("Which file would you like to...

int main()
{

char *input, *output;
FILE *ifp;

printf("Which file would you like to read from?\n");
scanf("%c", &input);
if ((ifp = fopen(input, "r")) == NULL)
{

thanks

I am trying to open a file to write too but the user needs the ability to select what file they want to open. How do I use fopen to open a string and not a filename?
