largest and smallest

i need to make a program that reads five different numbers but tells me the largest number and the smallest number. i finished most of it but i have problems displaying the largest and the smallest number in a sentence. i need it to say for the largest number "the largest interger is:" and for the smallest one, i need it to display "the smallest integer is:". what i finished looks like this...

Code:

---

# include <stdio.h>
int main (void)
{
int integer1;
int integer2;
int integer3;
int integer4;
int integer5;

printf("Enter first integer: \n");
scanf_s("%d", &integer1);

printf("Enter second integer: \n");
scanf_s("%d", &integer2);

printf("Enter third integer: \n");
scanf_s("%d", &integer3);

printf("Enter forth integer: \n");
scanf_s("%d", &integer4);

printf("Enter fifth integer: \n");
scanf_s("%d", &integer5);

if((integer1 > integer2)&&
(integer1 > integer3)&&
(integer1 > integer4)&&
(integer1 > integer5)){
printf("%d", integer1);
}

if((integer2 > integer1)&&
(integer2 > integer3)&&
(integer2 > integer4)&&
(integer2 > integer5)){
printf("%d", integer2);
}

if((integer3 > integer1)&&
(integer3 > integer2)&&
(integer3 > integer4)&&
(integer3 > integer5)){
printf("%d", integer3);
}

if((integer4 > integer1)&&
(integer4 > integer2)&&
(integer4 > integer3)&&
(integer4 > integer5)){
printf("%d", integer4);
}

if((integer5 > integer1)&&
(integer5 > integer2)&&
(integer5 > integer3)&&
(integer5 > integer4)){
printf("%d", integer5);
}

if((integer1 < integer2)&&
(integer1 < integer3)&&
(integer1 < integer4)&&
(integer1 < integer5)){
printf("%d", integer1);
}

if((integer2 < integer1)&&
(integer2 < integer3)&&
(integer2 < integer4)&&
(integer2 < integer5)){
printf("%d", integer2);
}

if((integer3 < integer1)&&
(integer3 < integer2)&&
(integer3 < integer4)&&
(integer3 < integer5)){
printf("%d", integer3);
}

if((integer4 < integer1)&&
(integer4 < integer2)&&
(integer4 < integer3)&&
(integer4 < integer5)){
printf("%d", integer4);
}

if((integer5 < integer1)&&
(integer5 < integer2)&&
(integer5 < integer3)&&
(integer5 < integer4)){
printf("%d", integer5);
}
return 0;
}

Use a loop and an array. What you did is not the way to do it.

You don't really need more than three variables to solve this problem: One that is the current input, one to hold the largest value, one to hold the smallest value. [Ok, if you want to make it a loop over x number of inputs, you will also need a fourth variable as the loop count].

Code:

---

#include <stdio.h>
int main()
{
  int a;
  int lar, less, flag;
 
  lar = less = flag = 0;
 
  for(i=0;i<5;i++)
  {
      printf("Num &#37;d : ", i);
      scanf("%d",&a);
     
      if(!flag){ less=a; flag = 1; }
     
      if(res < a)
        res = a;
     
      if(less > a)
        less = a;
  }
 
  printf("Result -> %d %d\n", res, less);
 
  getchar();
  return 0;
}

Looked for a samll program which i wrote quite a while ago. Which was just the similar to what u have asked. And i guess Mats is speaking about it as well.

That won't compile, as "a" is not declared.

Code:

---

#include <stdio.h>

int main(void)
{
    int n = 0, max = 0;

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

        printf("Current max: %d\n", max);
    }
    return 0;
}

Or with 2 variables :)

Well, that doesn't read exactly 5 numbers, nor does it tell you the smallest.

Nor does it give away the answer :)

Maps sorted. My bad, was editing few thing in the code before i posted and left that unchnaged.

i have a feeling that the person who posted this question is in the same uni and class as i am LOL because this is one of the question for today lab session

anyway.. what i did :

Code:

---

#include <stdio.h>

int main()
{
  int largest;
  int smallest;
  int input;
  int counter = 0;

  printf( "Enter an integer\n" );
  scanf( "&#37;d", &input );

  largest = input;
  smallest = input;

  while( counter < 4)
  {

  printf( "Enter an integer\n" );
  scanf( "%d", &input );     

      if ( input > largest )
      {
        largest = input;

      }

      if (input < smallest )
      {
        smallest = input;

      }

      counter+=1;
  }


  printf( "The biggest integer is %d\n", largest );

  printf( "The smallest integer is %d\n", smallest );

  return 0;

}

btw.. flag is.... counter?
