Question

How can I arrange the values of a,b,c in ascending order where a will gets the lowest value and variable c gets the highest value the values of the variables are: a equals 15,b equals 10,c equals 2

Answer 1

use quicksort.

Answer 2

bubble sort works fine too.

Answer 3

can u show me the code please?

Answer 4

one moment

Answer 5

oh which language?

Answer 6

C++

Answer 7

alright, but for C++ I think there's a library function

Answer 8

its okay, ^^

Answer 9

http://www.cplusplus.com/reference/algorithm/sort/
go to CS area

Answer 10

then what?

Answer 11

Make a loop, Compare first element with subsequent elements if A[1] > A{2} => A[1]=b => A[1] = A[2] => A{2]=b Then compare A[3] and so on

Answer 13

this is the code?

Answer 14

i'll just put the values??

Answer 15

only the quickSort function at the very top is the sorting function

Answer 16

this one?


#include <iostream>
using std::cout;
using std::endl;

void quickSort(int A[], int left, int right)
{
int i = left, j = right;
int tmp;
int pivot = A[(left + right) / 2];
while (i <= j) {
while (A[i] < pivot)
i++;
while (A[j] > pivot)
j--;
if (i <= j) {
tmp = A[i];
A[i] = A[j];
A[j] = tmp;
i++;
j--;
}
};
if (left < j) quickSort(A, left, j);
if (i < right)quickSort(A, i, right);
}

Answer 17

right

Answer 18

okay so where will i put the A,B,C ??

Answer 19

well, except the #include <iostream> using std::cout; using std::endl; part...

Answer 20

oh okay. then where will i put their values?

Answer 21

you can set A,B, and C, to be integer elements of an array.

Answer 22

and simply sort the array :-D

Answer 23

actually im just new on C++

Answer 24

and i dont know that array sorry

Answer 25

I'm new to C++ too; that code is from a C implementation. In C++ there are nicer data structures like vectors and sets.

Answer 26

well if you haven't gotten to arrays and pointers yet do it Ishaan's way

Answer 27

can u put the A,B and C on the code and their values? im just a newbee seriously

Answer 28

No need to apply sorting algorithm for only 3 values,simply write a macro that will do the job for you ..

Answer 29

btw C has qsort() inbuilt which could be used but still overkill.

Answer 30

yeah qsort() is a C standard library function (though it's not usually used)

Answer 31

just #include <cstdlib> and call qsort()

Answer 32

lolz I used it often in SPOJ and I am sure many do still now

Answer 33

what??

Answer 34

confused O__O"

Answer 35

#include <cstdlib> is C++ header

Answer 36

#include <stdlib.h> is more C

Answer 37

we were using C++

Answer 38

okay lets go back to my problem. so how can i start doing it?

Answer 39

start writing a macro it's really simple.

Answer 40

what's macro? sorry :(

Answer 41

Something like this:

#define M(a,b) ((a)>(b))?(a):(b)

Answer 42

then?

Answer 43

sorry.., I am not doing your homework

Answer 44

Hmm you can use If-else for comparing 3 integers

Answer 45

yeah, either a function or a macro

Answer 46

if else would be cubersome Ishaan ..

Answer 47

*cumbersome

Answer 48

actually this isn't a homework. i just want to learn but i can't

Answer 49

Max = M(M(a,b),c); there you go..

Answer 50

if-else would be too much for my really small brain ...

Answer 51

and in C++ you can use stl algorithms then it will be cake-walk

Answer 52

the one that you've given to me,the code, i will use that for my problem?

Answer 53

here's the thing. can u show me how to do it? then i'll try to do that and see if i can make another one.

Answer 54

Right If-else would be tough

Answer 55

i just dont know how to do it. please show me the code then i'll make another one which i will answer all by myself.

Answer 56

please? anyone? :((

Answer 57

if you new to programming choose another language to learn, like JAVA or Python if it's not your homework :D

Answer 58

yep it wasn't but i want to learn this thing. if u dont want me to help then fine :/

Answer 59

why you want to learn C++?

Answer 60

to build computer viruses!
