    Talking help would be appreciated(newbie at this)

    Heres the problem

    Write a program that inouts a serie of integer and pass them one at a time to function even which use the remainder operator to determine if an integer is even. The function should be integer arguement and return 1 is the integer is even and 0 otherwise.

    Heres what i come out with so far

    Code:
    #include <stdio.h>
    
    int main()
    {
    	int integer1;
    	int odd;
    	int even;
    	int remainder;
    
    	printf("Enter an integer\n");
    	scanf("%d", &integer1);
    	
    	remainder = (integer1%2);
    
    	if (remainder == 0) {
    		printf("%d", integer1);
    		printf("1\n");
    	}
    	if (remainder != 0) {
    		printf("%d", integer1);
    		printf("0\n");
    	}
    	
    	return 0;
    }

    Hope this helps in your quest. From the FAQ board FAQ: How to test whether integer is even or odd
    When no one helps you out. Call google();

    if anyone can correst my program by rewriting he whole program it would be helpful because i dont really get what to so to correct it.

    Your program doesn't work?
    Code:
    if (remainder )
    {
       printf("You entered %d, it is odd.\n"
                 "Here's your 0.\n\n", integer1);
    }
    else
    {
       printf("You entered %d, it is even.\n"
                 "Here's yor 1.\n\n", integer1);
    }
    Are you supposed to print 1 if even, or return 1. There's a difference.

    ok, read your post a little slower...

    Code:
    int yourfunc( int value )
    {
       //test whether value is even or odd
      ...
    
      if it's odd
          return 0;
      else
          return 1;
    }
    So, just make a function like this, and call it from main with your integer1 .

    It can be done without an if statement.
    Code:
    Function(int Value)
    {
       Value %= 2;
       return !Value;
    }

    im new at this too.. but did you forget to put your cast in the printf:

    old code
    Code:
    	printf("Enter an integer\n");
    	scanf("%d", &integer1);
    new code
    Code:
    	printf("Enter an integer\n", integer1);
    	scanf("%d", &integer1);
    hehe, maybe

    good call, I didn't think of that.

    as mentioned in the other post, you don't need to do anything special with printf unless you're printing the value of a variable.
    ex.
    Code:
    printf("this is a line without a variable\n");
    will display
    Code:
    this is a line without a variable
    and
    Code:
    int number = 1;
    printf("this one prints the value of the variable \"number\"\n"
           "number's value is %d\n", number);
    will display
    Code:
    this one prints the value of the variable "number"
    number's value is 1

    Are you kidding? You've been given enough hints. Here's another one.
    Code:
    #include <stdio.h>
    OO(O0){return !(O0 & 1);}main(_OO,_00)
    int*_00;{int _0O;char _O0[]="How many\
     integers will you enter? \0is\0odd.\n\
    \0even.\n\0Enter an integer: \0";for(
    _00=&_0O,printf("%s",_O0),scanf("%d",
    _00),_00=&_OO;_0O;printf("%s",_O0+51),
    scanf("%d",_00),OO(*_00)?printf("%d %s\
     %s",*_00,_O0+35,_O0+44):printf("%d %s \
    %s",*_00,_O0+35,_O0+38),_0O--);return _0O;}
    Good luck with that class.
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    from reading the problem more closely now and testing my program, none of the code in this thread enable someone to enter series of numbers(more than one) and reads them in one at a time and inputs those number out in order. returns a 1 if the 1st number is a even number and 0 if its a odd number, same for the other numbers.

    because the problem saids

    Write a program that inputs a SERIES OF INTEGERS and pass them one at a time to function even which use the remainder operator to determine if an integer is even. The function should be integer arguement and return 1 is the integer if even and 0 otherwise.

    I dont get this sentence at all: pass them one at a time to function even

    Run result should be something like this

    Enter an integer
    8 93 92
    1 0 1
    Press any key to continue

    It's basically asking you to create a function called 'even' that returns a 0 if odd and 1 if even. So I would start by creating a function, I'm pretty sure there are enough hints in the thread to go about creating it, but since you still seem pretty confused:

    Code:
    int even(int input)
    {
       return (input % 2 == 0);
    }
    Now you should be worrying about how to get the actual series of integers, theres a number of ways of going about doing this - one of the simpler options is to ask the user how many integers that are expecting and then keep reading in integers and storing it in an array or something. Once you read in all the integers (and processed them using even()) simply just print the array out. I'm pretty sure there are more efficient ways though
