#define ITEMS 5
#define MAXCHAR 20

void main()
{
    char string[ITEMS][MAXCHAR], dummy[MAXCHAR];
    int i=0,j=0;

    printf("Enter names of %d itemsn",ITEMS);

    while(i<ITEMS)
        scanf("%s",string[i++]);

    for(i=1;i<ITEMS;i++)
    {
        for(j=1;j<=ITEMS-1;j++)
        {
            if(strcmp(string[j-1],string[j])>0)
            {
                strcpy(dummy,string[j-1]);
                strcpy(string[j-1],string[j]);
                strcpy(string[j],dummy);
            }
        }
    }
    printf("alphabetical listn");

    for(i=0;i<ITEMS;i++)
        printf("%sn",string[i]);
}
