How to improve the given C code?

Question

C++ / C#

How to make this code faster/better?
I want to make the code faster than it is now, if possible.

#include <time.h>
#include <stdio.h>
#include <stdio.h>
#pragma warning(disable : 4996)
#pragma warning(disable : 4552)
#pragma warning(disable : 4013)
int main() {
  int start = clock(); int a = 1000; int b = 0, c = 0; int d = 1;
  FILE* f;
  while ("") {
    for (c < d; a > b; b++) {
      f = fopen("2200.txt", "a");
      fprintf(f, "\ntext");
      fclose(f);
    }
    for (c < d; a = b; c++) { b = 0; }
    if (c == d) {
      double elapsed = (clock() - start) / 1000.0;
      printf("\nTime elapsed in ms: %f", elapsed);
      getch();
    }
  }
}

Answer 1

for (c < d; a > b; b++)
replace with
for (;c < d, a > b; b++)
and also
for (c < d; a = b; c++)
replace with
for (;c < d,a == b; c++)
