That is harsh :) Yet amusing. Luckily for everyone else on the forum I am equal opportunistic with both help and insults.

also i wanted INT_MIN and INT_MAX to print out the smallest and largest of the inputted numbers.

So you can, as you read in a number, say "Hey! Is this the smallest number?" If it is, keep hold. If not, don't. (And of course the same for largest number.) You can't have INT_MIN and INT_MAX for variable names, just like you can't have if and for. Already taken, sorry.

No arrays eh? That is even easier to code and less overhead :)

Example:

Code:

---

/*
 * This program prints the smallest number, the largest number,
 * and the average of all the numbers.
 */
#include <stdio.h>
#include <limits.h>

int main(void) {

        int input;
        int total;
        int avg;
        int count;
        int min = INT_MAX, max = INT_MIN;

        total = 0;
        count = 0;

        printf("enter some numbers, and then anything else to the end:\n");

        while (scanf("&#37;d", &input) == 1) {
                if(input > max)
                      max = input;

                if(input < min)
                      min = input;

                total += input;
                // count = ++count;
                ++count;
                printf("%d\n", input);
        }

        if(count == 0)
        {
                fputs("You are no fun. Thank you for using my program anyway...", stdout);
                return 0;
        }
           
        avg = total/count;
         
        printf("smallest value is %d\n", min);
        printf("largest value is %d\n", max);
        printf("total is %d\n", total);
        printf("count is %d\n", count);
        printf("avg is %d\n", avg);

     
}

Well if u arent using something as an array, everytime u use scanf for the input the previous data is deleted. So there is Abosolutely no way that ud be able to reference the back to the numbers u entered. So there, u need something to keep track of the nums, something for beginers an array id say

Darn Matt, u made my previous response seem thinkless, haha, agreed there, nice work!

Not necessarily. Only if he needs to look at the numbers ever again. He simply needs to know what was the smallest one input, and which was the largest input.

Yea as i responded above, u won! No comments :)

Haha, its ok. I know what I posted was along similar lines to what tabstop said, but these days he has been abbreviating his responses nearly as badly as I have so its hard to type faster than him some days.

Actually, I don't know what has gotten into me that I am being so trusting of the user. I added the correct code to fix the above program from user error.

Yea i see, i hadnt read u guys responses before i wnt typing about arrays. Sweet code, my brains were thinking along other lines, referencing back n stuff, keeping records that idea

Cool, fun eh how a smal prog can turn into a big project. Guess Cleepy owes u thanks.

I initially recommended the same thing thinking that was what the professor was wanting. But luckily he just needed something simple. The making sure count is not zero is VERY important. It will not only prevent the two dummy min/max values from being printed, it will also prevent a division by zero.

Code:

---

/*
 * This program prints the smallest number, the largest number,
 * and the average of all the numbers.
 */
#include <stdio.h>
#include <limits.h>

int main(void) {
        int input, total, count;
        int min = INT_MAX, max = INT_MIN;

        printf("enter some numbers or 'Q' to quit:\n"); /* Again... idiot proofing */
        for(total = 0, count = -1, input = 0; scanf("&#37;d", &input) == 1; ++count, total += input)
        {
                if(input > max)
                      max = input;

                if(input < min)
                      min = input;
        }

        if(!count)
        {
                fputs("You are no fun. Thank you for using my program anyway...", stdout);
                return 0;
        }
           
        printf("smallest value is %d\nlargest value is %d\ntotal is %d\ncount is %d\ncount is %davg is %d\n",
              min, max, total, count, total / count);
        return 0;     
}

^ If I wrote it I would probably have done it more than this *shrugs* its not my homework anyway.

Yea cool cool, takes off a lot of the errors that could happen, real good, i wudnt have gone all that way, id probably left the rest for em, lol :)
