    char b[1][80];
    int i,j;
    for(i=0;i<5;i++){
        scanf("%s",a[i]);
    }
    for(i=0;i<5;i++){
        strcpy(b[0],a[i]);
        for(j=i+1;j<5;j++){
            if(strcmp(b[0],a[j])>0){
                strcpy(b[0],a[j]);
                strcpy(a[j],a[i]);
                strcpy(a[i],b[0]);
            }
        }
    }
    printf("After sorted:\n");
    for(i=0;i<4;i++){
    	printf("%s\n",a[i]);
	}
