Answer 1

Here is my answer, I am currently in the same spot you were years ago.

I used only the syntax taught until this point in the books and it reduces the multiple spaces into one space only as required.

#include
int main(){
    int c
    int blanks = 0; // spaces counter
    while ((c = getchar()) != EOF) {        
        if (c == ' ') { // if the character is a blank
            while((c = getchar()) == ' ') { //check the next char and count blanks

                blanks++;

                // if(c == EOF){
                // break;
                // }
            }            
            if (blanks >= 0) { // comparing to zero to accommodate the single space case, 
                               // otherwise ut removed the single space between chars
                putchar(' '); // print single space in all cases                    
            }

        }
        putchar(c); //print the next char and repeat        
    }


    return 0;
}

I removed the break part as it was not introduced yet in the book,hope this help new comers like me :)
