C++

[Corey]

Hi guys I am working on a c++ program atm and I ran into a bit of formatting issue. My program is supposed to look like this

 

 

but instead this is what it looks like

 

 

 

I'm sure it can't be that complicated to fix, but i am stumped :|

 

 

 

#include <iostream>
#include <string>
#include <iomanip>

using namespace std;

int main()

{
 double sales[3][4]= {{1000.00,2000.00,3000.00,1000.00},{2000.00,3000.00,1000.00,2000.00},{3000.00,1000.00,2000.00,3000.00}};
 cout<<"\t\tQtr1\t\tQtr2\t\tQtr3\t\tQtr4"<<endl;

 for(int p=0;p<3;p++)


cout<<"\nDivision "<<p+1;



for(int i=0;i<3;i++)

{


	for(int j=0;j<4;j++)


cout<<fixed<<showpoint<<setprecision(2)<<sales[i][j]<<"\t\t";
cout<<endl;

}

cout<<endl;
return 0;


}

Your loops are not properly nested. Get rid of the first for loop and put cout<<"\nDivision "<<p+1; inside the brackets of the next for loop and above the last for statement. Change the p in cout<<"\nDivision "<<p+1; to i.

 

#include <iostream>
#include <string>
#include <iomanip>

using namespace std;

int main()

{
        double sales[3][4]= {{1000.00,2000.00,3000.00,1000.00},{2000.00,3000.00,1000.00,2000.00},{3000.00,1000.00,2000.00,3000.00}};
        cout<<"\t\tQtr1\t\tQtr2\t\tQtr3\t\tQtr4"<<endl;



for(int i=0;i<3;i++)

{

      cout<<"\nDivision "<<i+1;
      for(int j=0;j<4;j++)
       {                
       cout<<fixed<<showpoint<<setprecision(2)<<sales[i][j]<<"\t\t";
       }
       cout<<endl;

}

       cout<<endl;
       return 0;


}

thanks monkeysmack! I am still a noob at this stuff. knew my fellow would rescue me!

Java > C++

[monkeysmack]

Us s have to stick together!

Yes, most of my coding these days is in Java.

I took a java class last semester. Absolute Disaster! I think it was my teacher mostly

actually if you really want to be a good programmer C++ is a good choice cause most Java IDES is about drag things and stuff :/ .. unlikely C++ that you have to do everything manually function by function , Old school .

Java is, well, easy. It's programming, but for everything you want to do, there is already a function. For PHP for example, that is even more likely. C++ is only programming where nothing is free.

 

 

Anyway, a really easy tip. Start indenting correctly (and use always {} for if/for/etc) and you could have seen immediately what your problem was. Your first for-loop is for each row, your second is for each column in a row.

 

 

Ow, small note, which I usually do wrong every time. std::endl is really endline, "\n" is more the C-variant (and not really correct, for Windows you actually would have to use either \r\n or \n\r, I always forget).

[Corey]

thanks for the tips

why am i reading this, i don't understand a thing in this topic

[parrot]

std::endl and /n seem to be very similar, but I already ran into one program where the buffer flushing property of std::endl made the difference between running correctly and not running correctly, fwiw

[rolf]

^^ way to revive an old topic....

 

Anyway, the difference between \n and std::endl are a bit strange. Actually, you should compare \n and \r\n, \n is for Linux and \r\n is actually required for Windows. Although \n usually also works for Windows, with std::endl you solve that problem always at once for both environments.

[parrot]

wow no kidding huh?

 

Guess I should check the date next time.

 

My professor taught us \n and std::endl both, but all we're doing atm is console programs in windows.

Most of my coding as of late has been php / c#... lots of c#. I have to tell you, I got really sick of using MFC, my god... I don't think MS could make anything more confusing than that
