Help me again in C function.....

[[Student]]

Grrr!.....for me this is not a practice....because its hard to get it!........
so help me for my practice!....

my problem is i want to know how to get the lowest input of integers input by user with loop!....i get the highest integer...but in the lowest is the same with highest!.....
like a enter number 1 2 3 4 5

the highest is 5[correct]
the lowest is 5[wrong] ... plz help how to solve it

2nd problem is i want to know how to reverse that input of integers input by user with loop!..just like 1 2 3 4 5....and its same value like int a using loop!....scanf is the inside of the loop....looping 5 times...and i want to know how to reverse...that one value!....

plz help me in my two problems!....(don't use array) because in that topic i can't understand...i'm the C functions topic

here's my code!>..

#include<stdio.h>

OK... what's wrong with this picture...

    if(low > a)
    { low=a; }

[Subsonics]

You will need to keep track of both the highest and lowest number when you input your numbers. Right now, 'a' contains the last number.

  printf("Enter 5 numbers: ");
  for(int b=1;b<=5;b++){
             scanf("%d",&a);
             sum1+=a;
             pro1*=a;
  }

First things first, it's int main(void) and a return 0 at the end.

Your highest and lowest functions don't work because you only pass them one of the 5 values entered, namely the last of those. They will only print out either the default value (0 or 'a') or the number you pass them (last number entered, 5 in your case). Try it with the input 5 4 3 2 1, or 1 5 2 4 3 to see what happens.

This is because you try to store all 5 inputs in one variable, namely a. Arrays would be the normal way, but we can't use those, so you need to read them into 5 different inputs, say a, b, c, d and e respectively so that you know all 5 values when it comes time to do something with them. Then, you pass all 5 of those to the highest and lowest functions:

int a, b, c, d, e;
  int sum1=0;
  int pro1=1;
  printf("Enter 5 numbers: ");
  scanf("%d",&a);
  scanf("%d",&b);
  scanf("%d",&c);
  scanf("%d",&d);
  scanf("%d",&e);
...
                         printf("\nHighest Input is %d",highest(a, b, c, d, e));
                         printf("\nLowest Input is %d",lowest(a, b, c, d, e));

You can pass those 5 variables to add, pro and reverse functions too. Hopefully that gets you going in the right direction.

[Subsonics]

To just get the highest and lowest number you can do like this:

        int highest = INT_MIN;
        int lowest = INT_MAX;
        int b, a = 0;

        printf("Enter 5 numbers: ");

        for(b = 0;b < 5;b++){
                scanf("%d",&a);

                if( a > highest )
                        highest = a;

                if( a < lowest )
                        lowest = a;
        }

        printf("lowest: %d\nhighest: %d\n", lowest, highest);

If you need all numbers later, just make 'a' an array, and access it through a[b] inside your loop.

Hey!...thanks a lot to all of you i will test all your suggestions!....

[Subsonics]

Keep in mind that INT_MAX and INT_MIN are defined in limits.h, so you will need to include that if you plan to use them. (Forgot to include it in my example).

[[Student]]

what's INT_MIN declared?

int highest = INT_MIN;
int lowest = INT_MAX;

Hey Sir!.... how do i reverse the 5 inputs?...plz help me!

[quzah]

Read them in one way, print them out the other way. Give it a shot, and we'll give you a hand after you've tried it.


Quzah.

[[Student]]

then how!.....is it possible?

[quzah]

No. It is one of the great scientific mysteries of our time: How to reverse a series of numbers. We have dedicated supercomputers working 24-7 trying to solve this complex issue.


Quzah.

[[Student]]

hahahaha....... what about in palindrome?......it's very impossible!..... ;D

[quzah]

Palindromes are by definition already reversed, so why would you need to ever reverse a palindrome?

We aren't here to do your work for you. Put it into words, try it out on your own, then post your attempt, what it does, and where you are stuck. In short, you need to know How To Ask Questions The Smart Way.
