Answer 1

I am at the same point in the book. and my solution goes with making a count++ if blank is found and making the count back to zero if anything other than blank is found.

For if statement I put another another check to check value of count (if zero) and then print.

Though at this point of learning I shouldn't be concern about efficiency of two methods but which one is efficient a.) Accepted solution here with while inside while or b.) the one I suggested above.

My code goes like below:

#include 


main()
{
    int count=0,c;
    for( ; (c=getchar())!=EOF; )
    {
        if(c==' ')
        {
            if(count==0)
            {
                putchar(c);
                count++;
            }
        }
        if(c!=' ')
        {
            putchar(c);
            count=0;
        }


    }
}
