C program remove spaces, blanks from a string

C programming code

#include <stdio.h>

#include<conio.h> 

void main()

{

   char text[100], blank[100];

   int c = 0, d = 0;

   clrscr();

   printf("Enter some text\n");

   gets(text);

   while (text[c] != '\0')

   {

      if (!(text[c] == ' ' && text[c+1] == ' ')) 

      {

        blank[d] = text[c];

        d++;

      }

      c++;

   }

  blank[d] = '\0';

  printf("Text after removing blanks\n%s\n", blank);

  getch();

}
