    Program to print input to output by removing extra balnks :)

    Hie everyone.. I am a newbie and learning c programming.. I refered the site and found ansic is the best book) thanks to cprogramming.com.. I am reading it..

    Therein the author asked us to write a program to print input to output by removing extra balnks..

    I have writen the following code.. No errors! But it does not print anything except for the printf statement... why so?

    Code:
    #include<stdio.h>
    #include<stdlib.h>
    
    int main()
    {
        int v,bcount=0;
    
        printf("Type in the string that you want to edit...\n \n Now!\n");
    
        while( (v=getchar()) != EOF);
    {
        if(v!=' ')
            {
                putchar(v);
                bcount=1;
            }
    
        else if(v==' ')
           {
               while(bcount==1)
            {
                putchar(v);
                ++bcount;
             }

    Oh.. lemme post the exact question to you all.. Exercise 1-9. Write a program to copy its input to its output, replacing each string of one or
    more blanks by a single blank. What i need to know is what is wrong with the code I have written

    Watch the ; at the end of this line.

    > return(7);
    A successful main returns 0
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
