C++ Question

[wreglefan]

This is a question on my study guide and I believe the answer is: 543210
is this correct?

with the following input: 456789
what will print out?

int i,tp; int myary[6];
char khar;
for(i=0; i<6; i++)
{
cin.get(khar);
myary[1] = khar – ‘0’;
}
for(i=1; i<6; i++)
myary[i-1] = myary[i-1] + myary[i];

for(i=0; i<6; i++)
cout<<myary[i];
cout endl;

It would be interesting to hear how you got this result.

[wreglefan]

my array holds 6 values and I know it prints in reverse but I wasn't sure if it was just 54 or I had to let it hold 6 places in my array. I am unsure that is why I am asking for help

[vlad from moscow]

I do not see where the array is printed in the reverse order.

[Dy7SLyTq]

there are too many errors in that first of all

[wreglefan]

well idk it is a question on my study guide

[vlad from moscow]

It is strange that your guide contains so many typo.:)
For example in this code snip

for(i=0; i<6; i++)
{
cin.get(khar);
myary[1] = khar – ‘0’;
}

only the element with index 1 (one) is assigned.

And here

cout endl;

you omitted operator <<.

If do not take into account the typo this loop

for(i=1; i<6; i++)
myary[i-1] = myary[i-1] + myary[i];

does the following

myary[0] = myary[0] + myary[1];
myary[1] = myary[1] + myary[2];
myary[2] = myary[2] + myary[3];
myary[3] = myary[3] + myary[4];
myary[4] = myary[4] + myary[5];

So you can calculate yourself what values the array will have.

[Dy7SLyTq]

#include <iostream>
#include <vector>

using std::cout;
using std::cin;
using std::vector;

int main(int argc, char *argv[])
{
	vector<int> Container(1);
	int Counter = 0;
	
	while(cin>> Container[Counter++])
		Container.resize(1);
		
	vector<int> Copy(Container.size() - 1)
	
	for(auto I : Container)
		Copy[Copy.size() - I] = Container[i];
		
	for(auto I : Copy)
		cout<< Copy [I] <<" ";
}

edit: accidently put a 1 where an I should be in the first for loop

@DTSCode

As I already said you understand nothing in programming and as the result your advices and comments do more harm than good.

This stupid code

	while(cin>> Container[Counter++])
		Container.resize(1);

will result in a program abort.

[Dy7SLyTq]

oh really and how is that?

[edit] im being sarcastic my code is fine. im merely humoring you while you try to prove me wrong. i know my code works thought [/edit]

@DTSCode

oh really and how is that?

As I said in other thread I am not your professor. So try to understand it yourself or wait until someone experienced will point out the bug.

[Dy7SLyTq]

thank god you arent my professor you cant code to save your life. as i said i was being sarcastic because there is no bug

[vlad from moscow]

I will not even speak about that code shall not be compiled. There is no any sense to spend time to such genius as you.:)

[Dy7SLyTq]

really because i just compiled it. the only issue (and i typed it on the fly so thats why i made 1 mistake) was i made a 1 where an I should be. it compiled and ran fine

[vlad from moscow]

It seems that you are incurable.
Without any compiler I see that variable i was defined nowhere.

Copy[Copy.size() - I] = Container[i];

Change your brain!

[Dy7SLyTq]

you know what vlad? when you learn to code come talk to me. i will just ignore you until then because so far you have been arguing with defenses poorer than a third world country and at times given no defense at, just hoping that i will take your current assertion as fact. i know im right and i dont need to the approval of a lowly forum troll who must take his frustration out on those stupid enough to lower themselves to your level. (i am unfortunately referencing myself). so good day. i really hope you can one day support your arguements
