    if-else prob..very basic so sorry to trouble u guys

    hey, sorry to trouble u guys.
    ok, i've got a prob...the qn goes like this:
    the user is supposed to input 10 integers (can be positive or negative) and write a prog to select the 2 largest integers and print these 2 largest integers...

    ok, my prog goes like this but it does not work...WHY?i don't understand...oh and i'm using a standard ANSI compiler.

    #include <stdio.h>

    main ()
    int num1, num2,.............num10;
    int ans1, ans2;

    printf ("10 intergers pls:");
    scanf ("%d%d%d%d%d%d%d%d%d%d", &num1, &num2,...&num10);

    if (num1 >num2){
    ans1 = num1;
    ans2 = num2;

    if (num1 <= num2){
    ans2 = num1;
    ans1 = num2;

    if (ans1 < num)
    ans1 = num3;

    if (ans2 < num3 && ans1 >= num3)
    ans2 = num3;
    /*same selection process for num4 to num10*/

    printf("the ans is %d and %d", ans1, ans2);

    return ;

    is the selection process wrong?how shld it be corrected?

    mhm, read all numbers in an array (using a loop)! Then you can easily sort the all numbers using qsort of stdlib.h!

    i don't think that so many variables are good...
    Hope you don't mind my bad english, I'm Austrian!
