Question

C++

How would I sort my output to evaluate it by sorting the column by it's size? I didn't include my full program but here is the main.cpp where i'm supposed to sort the output by column size.

//User Libraries
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;

//User Libraries
#include "Table.h"
#include "Triangle.h"

//Global Constants

//Function Prototype
void prntRow(RowAray *,int);
void prntTab(Table *);
void prntTri(Triangle *);

//Execution Begins Here!
int main(int argc, char** argv) {
//Initialize the random seed
srand(static_cast<unsigned int>(time(0)));

//Declare Variables
// creates a random number of rows from 1 to 10
int rows=(rand()%10)+ 1;
//creates a random number of columns from 1 to 10
int cols=(rand()%10 )+1;
int perLine=cols/2;

//Test out the RowAray
RowAray row(cols);
  
//Print the RowAray
cout<<"The Row Array size = "<<row.getSize()
<<" printed "<<perLine<<" per Line";

prntRow(&row,perLine);


//Test out the Table
Table tab(rows,cols);

//Print the Table
cout<<"The table size is [row,col] = ["<<rows<<","<<cols<<"]";
prntTab(&tab);

//Test out the Triangular Table
Triangle tri(rows);

//Print the Triangular Table
cout<<"The triangular table size is [row,row] = ["<<rows<<","<<rows<<"]";
prntTri(&tri);

//Exit Stage Right
return 0;
}

//Fill a triangular matrix
int **fillAry(int *col,int n){
int **array=new int*[n];
for(int i=0;i<n;i++){
array[i]=new int[col[i]];
}
for(int i=0;i<n;i++){
for(int j=0;j<col[i];j++){
array[i][j]=rand()%9+1;//1 Digit numbers [1-9]
}
}
return array;
}
void prntRow(RowAray *a,int perLine){
cout<<endl;
for(int i=0;i<a->getSize();i++){
cout<<a->getData(i)<<" ";
if(i%perLine==(perLine-1))cout<<endl;

}
cout<<endl;
}

void prntTab(Table *a){
cout<<endl;
for(int row=0;row<a->getSzRow();row++){
for(int col=0;col<a->getSzCol();col++){
cout<<a->getData(row,col)<<" ";
}
cout<<endl;
}
cout<<endl;
}

void prntTri(Triangle *a){
cout<<endl;
for(int row=0;row<a->getSzRow();row++){
for(int col=0;col<=row;col++){
cout<<a->getData(row,col)<<" ";
}
cout<<endl;
}
cout<<endl;
}
