    Working in 'C'...why do u want one single command to sort....

    implement any of the sorting algo.

    linear sorting, quick sorting etc.

    Thats the best way to learn.

    Here is simple code for sorting

    Code:
    #include<stdio.h>
    
    int main()
    {
    
       int a[8] = {1,22,5,4,9,6,7};
       int temp =0,i=0 ,j=0;
       for (i=0; i<7; i++) {
         for( j=i; j<7; j++) {
           if( a[i] > a[j]) {
              temp = a[i];
              a[i] = a[j];
              a[j] = temp;
          }
        }
      }
    
       printf("\n sorted array is ");
       for ( i=0; i<7; i++)
         printf("\n a[%d] = %d\n ", i, a[i]);
    
       return 0;
    }
    N'joy

    Or use the qsort function:
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    int intcmp(const void *v1, const void *v2) { return(*(int *)v1- *(int *)v2); }
    
    int main()
    {
       int i, a[10] = { 9, 8, 7, -5, 99, -1, 0, 1, -9, 34 };
    
       qsort((char *)a, sizeof(a)/sizeof(*a), sizeof(*a), intcmp);
    
       for(i=0; i<10; i++) printf(" %d",a[i]);
    
       return 0;
    }

    Look, you'll need an algorithim to sort an array, you can find a lot of algorithims, an easy one to understand is Bubble sort, isn't so fast, but it's easy:

    Before using qsort please check whether you have the libraray for that otherwise your program won't compile.

    On unix it usually come as Fortran Library routine.

    ( library named as libF77.a ).

    qsort is an ANSI standard function, prototyped in stdlib.h
    When all else fails, read the instructions.
