Draw Progress Bar using C Program

Program #29

Description:
Draw Progress Bar using C Program.  ASCII character plays to vital role to make it.
ASCII Positions of { 176, 177, 178 and 220} are good to make Progress Bar.

Row, Column, Progress bar length and ASCII Position used to make progress Bar
*/

#define BLOCKS_TO_PRINT 25;
#define ASCII_POSITION 220;

/* !Important:
  Character Position 176, 177, 178 and 220
  are good to make Progress Bar */

void main() {
   int i, col, row, blocks;
   char myAscii;
