    finding minimum in array

    i have an array (d_available[i])with some zero elements and non zero elements i want to find the minimum of the non zero elements (min_available)

    this is what i thought will work but still gives me 0 as minimium
    Code:
    min_available=d_available[0] ;
    for(i=0;i<NROWS;i++){
         if (min_available>d_available[i] && d_available> 0)
                    min_available=d_available[i];
     
                        }

    Test for the minimum, and if one is found, add a number onto an accumulator.
    The world is waiting. I must leave you now.

    I believe i see the problem. You have this:
    Code:
    min_available=d_available[0] ;
    for(i=0;i<NROWS;i++){
         if (min_available>d_available[i] && d_available> 0)
                    min_available=d_available[i];
     
                        }
    It should be this:

    Code:
    min_available=d_available[0] ;
    for(i=0;i<NROWS;i++){
         if (min_available>d_available[i] && d_available[i]> 0)
                    min_available=d_available[i];
     
                        }
    Does this work?

    min_available=d_available[0] ;

    What if this already is 0 ?

    C# Code would look something like this probably:

    PHP Code:
    using System;

    namespace 
    ConsoleApplication2
    {
        class 
    Class1
        
    {
            [
    STAThread]
            static 
    void Main(string[] args)
            {
                
    int[] array = new int[10];
                
    int min int.MaxValue;
                
    bool found false;

                foreach( 
    int i in array )
                {
                    if( 
    && min )
                    {
                        
    found true;
                        
    min i;
                    }
                }

                if( ! 
    found 
                {
                    
    Console.WriteLine"No nonzero values in array" );
                }
                else
                {
                    
    Console.WriteLine"The minimum nonzero value was {0}"min );
                }
            }
        }

    When in doubt, read the FAQ.
    Then ask a smart question.
