How to make a progress bar using C program with percentage?

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>
#define MAX 100000
#define WIDTH 100
void main()
{
  long i;
  float p = 0.0;
  int c  = 0, x=0, last_c=0;
  fprintf(stderr, "%3d%% [", (int)p);
  for (x = 0; x < c; x++){
    fprintf(stderr, "=");
 }
  for (x = c; x < WIDTH; x++){
    fprintf(stderr, " ");
 }
  fprintf(stderr, "]");
  for(i = 1; i < MAX+1; i++){
    p = i*100.0/MAX;
    c = (int) p;
    fprintf(stderr, "\n3[F");
    fprintf(stderr, "%3d%%", (int)p);
    fprintf(stderr, "3[1C");
    fprintf(stderr, "3[%dC=", last_c);
    for (x = last_c; x < c; x++){
      fprintf(stderr, "=");
  }
  if(x<WIDTH){
      fprintf(stderr, ">");
    }
    last_c = c;
  }
  fprintf(stderr, "3[EDone\n");
}
