Finding smallest number from an array

[gaza165]

im looking to write a function to find the smallest number in an array. is this right??

 

  for(i = 0; i < count; i ++)
  {
    printf("%2d> ",i+1);
    scanf("%d", &numbers[i]);
    sum += numbers[i];

smallest = numbers[0];
if(numbers[i] < smallest) 
{
smallest = numbers[i];
}

  }

Why don't you just use asort();

i want to be able to write my own function to show my brain power.

U can use this function to find smallest element in array.

 

$smallest = min($array);

Good for you. No shame in that....however looking at that code makes my head hurt...LOL....

 

I can tell you real quick that your for statement is wrong.

 

You need to use $i, not just "i"....

yeah i know that, but i dont want to use in built functions to do it i want to hard code my own if statements.

This doesn't look like php code to me

It looks psuedo or maybe from another language...

Thi si C

[Mchl]

It's C(++), and apart from finding minimum, also reads data from input (scanf) and calculates the sum (which is not necessary for finding minimum)

 

The code for PHP would look a bit different, but the basic idea stays the same.

[sasa]

move smallest = numbers[0]; before for loop, and then you can start your loop with 1

[gaza165]

you are right guys, it is C but i didnt know who else to turn too!!!

 

i have got it now guys thankyou and sorry if i have wasted ur time

 

#include <stdio.h>
int main(void)
{
  int numbers[10];
  int count;
  long sum = 0L;
  float average = 0.0f;
  int i;
  int j;
  int smallest;
  int largest;

  printf("\nEnter the numbers:\n");
  
  for(i = 0; ; i++)
  {
    printf("%2d> ",i+1);
    scanf("%d", &numbers[i]);
if(numbers[i] < 0) { break; }
sum += numbers[i];
count = i + 1;

//get smallest number from array.
smallest = numbers[0];
for (j =0; j < count; j++) {
     if (numbers[j] < smallest)
       smallest = numbers[j];
  }
  
//get smallest number from array.
largest = numbers[0];
for (j =0; j < count; j++) {
     if (numbers[j] > largest)
       largest = numbers[j];
  }


  }

  average = (float)sum/count;

  printf("\nAverage of the ten numbers entered is: %f\n", average);
  printf("\nSmallest number is: %d\n", smallest);
  printf("\nLargest number is: %d\n", largest);
  return 0;
}

I guess there aren't much examples for this written in PHP, since it has built in functions for that

Next time post this in the right forum ( PHP Core Hacking )

 

And I would also state at the beginning what language you are using, as in this forum it is assumed PHP, where as C programming is not the same Syntax as PHP, thus your answers are going to be interpreted that you do not know PHP syntax and thus pointed in that direction.

That doesn't really belong to PHP Core Hacking. As I understand, gaza165 wanted to write a function in PHP. It's just the code example he's found, is in C.

 

Or am I wrong?

 

Even then, it would rather go to Other Programming Languages

Oh...I thought he wanted that function as an element of php via being compiled....I could be wrong, my mind is in a daze and I cannot think straight today, but yea. I would probably be in the Other Programming Languages if that was what he was after.
