Thread: Help with if statement program plz

Hi,
I'm having difficulty writing a c program that asks the user to input 4 integers and it find the smallest and largest integer. I can only use 4 "if" statements to complete the program. I know the program does not compute the smallest integer correctly, but how can i fix it ? This is what I have so far..

Code:

#include <stdio.h>

int main()
{
  int num1, num2, num3, num4;
  int smallest, largest;
  
  printf("Enter four integers: ");
  scanf("%d %d %d %d", &num1, &num2, &num3, &num4);
  
 smallest = num1;

  if (num1 >= num2)
    if (num1 >= num3)
      if (num1 >= num4)
         largest = num1;
      else 
         largest = num4;
    else if (num4 >= num3)
      largest = num4;
    else 
      largest = num3;
  else 
    largest = num2;

printf("Largest: %d\n", largest);
printf("Smallest: %d\n", smallest);

return 0;
}

Ya, just set your biggest number to 0, loop through all numbers saying if this number is bigger, set it to your current number. Than you only need one if statement (two if you do the smallest number as well).

Code:

num = 0;
for(i=0;i<4;i++)
{
   if ( num[i] > num )
      num =  num[i];
}

And essentially do the opposite for the smallest number...

This will set num to the biggest number, because the only time it's overwritten is if a number is larger and vice versa. you will have to switch your implementation to an array.
