    regetting characters

    Hi Guys.

    When i use a while loop to scan in characters for instance
    Code:
    while ( (ch=getchar()) != EOF ) {
    	if ( ch == '\n' ) {
             	do this;
    		if ( (ch=getchar()) == '\n' ) {
    			do that;
    		}
    	}
    }
    what i basically want to do is check the character 1 ahead but then reclaim it back instead of losing that character.

    How can i do this?
    Im not after an array implementation.

    Cheers!

    >> what i want to do is just peek at the next character thats it but if use getchar() then it doesnt work because the character i peek at doesnt return

    isnt ungetc() used for files though?

    hmm clever.

    Dont have to think about ungetc() now.

    Thanks Salem
