problem with gets and bubble sort

Why is it that when I run this, I it will ask for the name the first time but when it loops around it will skip asking for name and go straight to asking for the account number??
I just cant seem to get it to work. Also my bubble sort will not sort the names, only acct # and the balance. Please help!

Code:

---

        struct info{char name[30]; int account_num; float balance;
        };
        struct info people[25];
        int x,a,y,temp=0;

//loop to collect info*/


                for(x = 1; x <= 3; ++x)
                {       
                          printf("Enter Name: ");
                    gets(people[x].name);
                   
            printf("Enter Account Number: ");                       
                    scanf("%i",&people[x].account_num);
                   
            printf("Enter Balance: ");               
                    scanf("%f",&people[x].balance);                       
                       
                    printf("\n");
                }

//bubble sort
                for (a=1; a<x-1;++a)
                {               
                for (x=1; x<3;++x)
                {
                if (people[x].account_num>people[x+1].account_num)
                {
                        temp = people[x+1].account_num;
                        people[x+1].account_num = people[x].account_num;
            people[x].account_num = temp;                                       
                           
                        temp2 = people[x+1].name[30];
                        people[x+1].name[30] = people[x].name[30];
            people[x].name[30] = temp2;
                                       
                               
                        temp = people[x].balance;
                        people[x].balance = people[x+1].balance;
            people[x+1].balance = temp;
           
                }/*end if*/
                }/*end nested for*/
                }/*end for loop*/
        char temp2=0;

scanf leaves new line in the buffer while gets read it as a line

there is a lot of samples on the forum - how to clear the stream after the scanf before reading with fgets (that should be used instead of gets - read FAQ)

Arrays start at zero, not one.
This means that there is no name[30], i.e. that's a buffer overrun. Besides, when swapping the items around you want to swap the entire string, not just one character.
You're the second person in a week to be unnecesarily trying to swap items by swapping every individual part of the structure. You don't need to do that in this case. This will do the whole swap for you just fine:

Code:

---

info temp = people[x+1];
people[x+1] = people[x];
people[x] =  temp;

I believe the reason is that K&R and most other C programming books, barely mention it.

BTW, I found the combsort you mentioned iMalc, and combsort 11 is a keeper, beating out Shellsort. and giving Qsort a run for it's money.

Yeah I've recommended it a few times because it's so simple and easy to understand once you get BubbleSort, yet good enough to compete with some of the more advanced algorithms.
A good QuickSort still beats it most of the time.
