c++ question

[ichihgo]

#include <iostream>#include<math.h>using namespace std;int main(){int num,i,z=0,newa;cin>>num;newa=num;while(z<num){    for(i=0;i<newa;i++)    {        cout<<'*';    }    cout<<endl;    newa=newa-1;    z++;}}

Input ==>6

any help

I don't know the answer, but from my experience of posting coding problems on the LTT forums, you'd be far better off asking this on Stack Overflow

try this 

newa-=1 instead of newa=newa-1

i cant see any other issues in your code, i will try it out later today when I have a PC with c++

I do but I keep getting negative votes and can't ask in it for 4 more days

one sec, editing

 

Nah it didn't

I asked the question wrongly 

[Enderman]

I worked perfectly now But why "newa-=1 instead of newa=newa-1" Fixed it !? 

 

idk why it worked and = - didnt...

I think its because -= does the - operation on a temporary value of newa, then sets the newa to that temp value, sort of like

newa=tempnewa=(temp-1)

but from my experience newa=newa-1 should have worked too...

oooh

well then let me work on a solution for that one sec

#include <iostream>#include<math.h>using namespace std;int main(){int num,i,z=0;cin>>num;while(z<=num){    for(i=0;i<=z;i++)    {        cout<<'*';    }    cout<<endl;    z++;}}

Thats a pretty weird way to do that task, it would be easier to convert to your desired output if both of them were for loops, like so:

#include <iostream>#include<math.h>using namespace std;int main(){int num;cin>>num;for(int i = 0; i <= num; i++){    for(int j = 0; j <= i; j++)    {        cout<<'*';    }    cout<<endl;}}

thanks for the help

 

 

I did find a way to fix it ... here how I did it

#include <iostream>#include<math.h>using namespace std;int main(){int num,newa;cin>>num; for(newa=0;newa<=num;newa++)  {    cout<<string(newa,'*');    cout<<endl;  }}

Many of the questions asked here wouldn't be accepted by the stack overflow community. Also, basic questions like this are pretty much always answered here.

But that doesn't print it reversed like you wanted. You want to do this to print it reversed

string(num - newa, '*');

Alternatively you can reverse the loop

for(newa = num; newa >= 0; newa--) // goes from num to zero instead of zero to num{    cout<<string(newa,'*'); // isn't changed because we reverse the loop    cout<<endl;}

Oh fair enough. I only say it because I've asked a couple programming questions before and not got any answers at all

Yeah, it's unfortunate but it's going to happen. With a (much) smaller community comes more limited knowledge. Stack overflow is an amazing resource that I use all the time, it's just beginners don't tend to know how to ask proper questions that meet their criteria and the down votes roll in.

 

I don't know what all your questions were about but I noticed one of them was on vba/access. I expect that no one who viewed it here may have known anything about working with them as they aren't as common to learn these days. For example, I've worked in VB.NET and MSSQL but not in vba or access.

 

tldr: We try but only know so much
