Thread: Sorting Elements in Lexicographical Order

Hey guys,
I have a code here i'm using for an exercise and basically it sorts a group of words of the user's choice and prints them in Dictionary order.

I have a few questions as I'm new to C programming and it's my first year of Computer Science.

First of all here's the code:
( sorry the code is like this.. don't know how to post it better )

Code:

1 #include<stdio.h>
2 #include <string.h>
3 int main(){
4    int i,j;
5    char str[10][50],temp[50];
6    printf("Enter 10 words:\n");
7    for(i=0;i<10;++i)
8        gets(str[i]);
9    for(i=0;i<9;++i)
10        for(j=i+1;j<10 ;++j){
11            if(strcmp(str[i],str[j])>0)
12            {
13                strcpy(temp,str[i]);
14                strcpy(str[i],str[j]);
15                strcpy(str[j],temp);
16            }
17        }
18    printf("In lexicographical order: \n");
19    for(i=0;i<10;++i){
10        puts(str[i]);
21    }
22    return 0;
23 }

1st Question: Line-7 the for loop explains that user's printing 10 words no more (True/False)
2nd Question: Line-9 & 10 don't understand this loop. Can someone explain me?
3rd Question: Now i understand that the user needs to print 10 words after hitting "Enter" but how to change this code so that the user can insert a serie of words using spaces instead of pressing "Enter"?
I want it to scan only the first line that contains my group of words.
example: john jordan jake yann max kevin
instead of:
john
jordan
jake
yann
max
kevin
