Thread: Running Into Two Problems...Help Needed

Well problem one consists of my program not writing its actions down to the file where I told it to. I checked and checked again; I seem to have the right codes maybe in the wrong order though...

EDIT:Well I just fixed one of the problem stil can't get this thing to print to the txt though.

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

void main(void)
{
char c;
int N,x,iter = 1;

FILE *outptr;
outptr=fopen("myOutput.txt","wt");
printf("\nPlease enter a value for N ");
scanf("%i",&N);
printf("\n ");
for(x = N, iter = 0; x > 1; x--)
{
printf("%i", x);
printf(" + ");
iter = iter + x;
fprintf(outptr, "%i", x);
fprintf(outptr, " + ");
}
printf(" 1 = ");
printf("%i", iter);
getch();
fclose(outptr);

int s(int a){return a+(a>0?s(a-1):0);}

Here's the fastest way to do this. You could just throw a printf statement in there and have it work the way you expect.

Yeah. Use fprintf if you want the output to a file. Mine just sums it up for you. Given a number, it generates its sum.

lol, Q this whole post was about I don't know why my fprintf doesn't work ? Nothing gets printed to output file... You got any ideas ?

After cleaning it up heavily, it works fine for me. Try this and see if it makes any difference

Code:

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

int main(void)
{
  int N, x, iter = 1;

  FILE *outptr;
  if ( ( outptr=fopen("myOutput.txt","w") ) != NULL ) {
    printf("\nPlease enter a value for N ");
    scanf("%i",&N);
    printf("\n");
    for(x = N, iter = 0; x > 1; x--)
    {
      printf("%i", x), fprintf(outptr, "%i", x);
      printf(" + "), fprintf(outptr, " + ");
      iter = iter + x;
    }
    printf(" 1 = "), fprintf(outptr, " 1 = ");
    printf("%i", iter), fprintf(outptr, "%i", iter);
    getchar();
    fclose(outptr);
  }
  else
    printf ( "Error opening file\n" );
  return 0;
}
