I'm doing my CP homework and I'm stuck at this exercise: Read from the keyboard the elements of a 3x3 float matrix. Rearrange the columns so that the sum of
each column's elements is smaller than the sum of the elements of the next column to the right.
What have I done wrong?

I'll copy paste the code if that helps:
#include
using namespace std;
float sumac(float x[3][3], int c);
void arrange(float x[3][3], int c1, int c2);
void main()
{
int i, j;
float x[3][3];
for (i = 0; i < 3; i++)
for (j = 0; j < 3; j++)
{
cout

Tip submitted thank you
use pastebin dumbass
CP= Computer Programming are you fucking retarded?
Yeah sure, I'm sure you pedos don't have codewords or anything.
fucking piece of shit
Right, right ;)
No one is going to help you with CP
If you can't figure this out then you are the pseud

When you compile and run the code, what output do you get?

>temp = x[r1][j] (inside arrange)

You need to read Structure and Interpretation of CP.
>not returning anything from arrange
kys
i'm pretty sure this is actually the problem with your code
you're expecting the array x to be different after passing it into the arrange function but that's not how c++ works
you need to also return the modified array and pass it into a variable
put matrix into a vector
sort vector
rebuiild matrix
I think that could work if i understood the problem

You are fucking filth! Read the sticky
You sound like that guy who thought it meant clown porn
#include
using namespace std;
// #define N 3
// don't use magic numbers
// check the sumac, i guess the problem is there. Didn't tested
float sumac(float[3][], int);
void arrange(float[3][], int, int);
int
main(int argc, char* argv[])
{
int i, j;
float x[3][3];
for (i = 0; i < 3; i++)
for (j = 0; j < 3; j++)
cin >> x[i][j];
for (j = 0; j < 3; j++)
for (i = 0; i < 3; i++) {
if (sumac(x, i) > sumac(x, i + 1))
arrange(x, i, i + 1);
}
for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++)
cout
OP is a faggot

Lurk moare m7
sort each row from smallest to biggest number and you are done, fag
how did you do that, how did you post code that was not an image?
