I need the output in my program to look like the white image

But instead I am getting this output:

This is my code:

#include "TriangularVertices.h$"$

#include

#include

void TriangularVertices::printTriangle$($int rows$)\{$

for $($int i $=1$; i rows; $++$i$)\{$

printSpacesBefore$($rows$,$ i$)$;

printNumbersRow$($i$)$;

std::cout $$ std::endl;

if $($i $!=$ rows$)\{$

printSpacesBefore$($rows$,$ i$)$;

printSlashesRow$($i$)$;

std::cout $$ std::endl;

$\}$

$\}$

$\}$

void TriangularVertices::printNumbersRow$($int row$)\{$

int startNumber $=$ calculateStartNumber$($row$)$;

for $($int i $=0$; i $$ row; $++$i$)\{$

std::cout $$ std::setw$(2)$ startNumber $+$ i;

if $($i $$ row $-1)$ std::cout ;

$\}$

$\}$

void TriangularVertices::printSlashesRow$($int row$)\{$

std::cout $$ std::setw$(1)$; $//$ Minor adjustment to slash alignment

for $($int i $=0$; i $$ row; $++$i$)\{$

std::cout ;

$\}$

$\}$

void TriangularVertices::printSpacesBefore$($int totalRows, int currentRow$)\{$

int spaces $=($totalRows $-$ currentRow$)*2$;

for $($int i $=0$; i $$ spaces; $++$i$)\{$

std::cout ;

$\}$

$\}$

int TriangularVertices::calculateStartNumber$($int row$)\{$

return row $*($row $-1)/2+1$;

$\}$

What part of the code am I doing wrong and how can I fix it$?$
