    I cant get the program to work

    int i , j , n , min ,minInd;

    void main(void)
    {
    int E[nb] ;

    printf("enter numbers");
    for (i=0; i<5 ; i++)
    {scanf("%d", E[i] );
    min= E[i];
    minInd=i;
    for (j=i+1; j<=n ; j++)
    {
    if (min > E[i])
    min= E[i] ;
    minInd= j ;

    }
    E[minInd]=E[i] ;
    E[i]=min;

    what kind of error are you getting??

    heres a rough idea

    Code:
    for(i=0;i<5;i++)
    for(j=i+1;j<5;j++)
    if(array[i]>array[j]
     {
      temp=array[i];
      array[i]=array[j];
      array[j]=temp;
     }
    this should do it, i think
    ive not tested it

    }
    I might be wrong, but I think you should put an address here instead of a variable, like this:

    scanf("%d", &E[i] );

    (Notice the &)
