Thread: C programming problem - Arrays

Hi again,
I have to create a program that should replace the smallest number in a 1-d array, on each turn
so 5 elements
1
2
3
4
5
it should be 9999 2 3 4 5
newline
9999 9999 3 4 5

Code:

#include <stdio.h>
#include <conio.h>
#define ROW 5
main()
{
    int unsorted[ROW] ;
    int i ;
    int j  ;
    int smallest[ROW] ;

    int temp ;
    
    printf("Enter %d numbers\n", ROW);
    for(i=0;i<ROW; i++) 
    {
        scanf("%d", &unsorted[i]) ;
    }
      for(i=0;i<ROW; i++) 
        {
            smallest[i] = unsorted[i] ;
        }
  
    
  
    for(i=0;i<5;i++)
    {
       if(unsorted[i] < smallest[i+1]) 
       {
            
            for(i=0;i<ROW; i++) 
            {
                temp = 9999 ;
                unsorted[i] = temp ;
            
               
                for(i=0; i<ROW; i++)
                {
                    printf("%d\t", unsorted[i]) ;
                }
               
            }
            
           
        }
    }
       
      
       
  
   
            
        


    getch() ;
}

Please help...it doesnt finish the loop!!

Code:

#include <stdio.h>
#include <conio.h>
#define ROW 5
main()
{
    int unsorted[ROW] ;
    int i ;
    int j  ;

    printf("Enter %d numbers\n", ROW);
    for(i=0;i<ROW; i++) 
    {
        scanf("%d", &unsorted[i]) ;
    }

  
    for(i=0;i<ROW;i++)
    {
       if(unsorted[i] <= unsorted[i+1])
       {
           unsorted[i] = 999 ;
           
           
           
           for(i=0;i<ROW;i++)
            {
                
                printf("%d\t", unsorted[i]) ;  
        
            }
            

        }
        

    }
    
    printf("\n") ;
    
     for(i=0;i<ROW;i++)
        {
           if(unsorted[i] <= unsorted[i+1])
           {
               unsorted[i] = 999 ;
               
               
               
               for(i=0;i<ROW;i++)
                {
                    
                    printf("%d\t", unsorted[i]) ;  
            
                }
                
    
            }
            
    
        }
       
        for(i=0;i<ROW;i++)
        {
           if(unsorted[i] <= unsorted[i+1])
           {
               unsorted[i] = 999 ;
               
               
               
               for(i=0;i<ROW;i++)
                {
                    
                    printf("%d\t", unsorted[i]) ;  
            
                }
                
    
            }
            
    
        }
   
            
        


    getch() ;
}

Ok i fixed the problem but i need about 3 loops!! why can't i use just one loop?

You should be able to (I didn't look at your code). Just need two variables, one for the lowest value and the index of that lowest value. Just do a comparison for each iteration and if the current value is lower than the lowest value, set that value as the new lowest value and that index as the index of the lowest value. After that iteration, you should have the index of the lowest value and then you can say array[lowestindex]=999; or whatever.
