Simple Array Coordinate Display Matching - c++

Question

I am attempting to create an array which takes user input and breaks at 99 99 but the multidimensional array does not stop taking inputted values. Another issue is getting the values to display on the grid down below in the visual representation. If more clarification is needed, please let me know.
#include <iostream>
#include <ctime>
using namespace std;
int main()
{
srand(time(0));
int organisms[22][22];
int rows,
columns;
int input[22][22];
int *output = new int[];
//filling array
for(int i=0;i<22;i++)
{
for(int j=0;j<22;j++)
{
organisms[i][j]=0;
}
}
//column output
cout<<"\t\t\t\t\t\t\t\t\t\t\t\t\tColumn\n\n";
for(columns=1;columns<21;columns++)
{
cout<<"\t"<<columns;
}
cout<<"\n\n\n";
//Row and data output
for(int i=0;i<20;i++)
{
cout<<"Row "<<i+1<<"\t";
for(int j=0;j<20;j++)
{
cout<<organisms[i][j]<<"\t";
}
cout<<endl;
}
cout<<"\n\n\n";
cout<<"Enter each cell in first colony use row space column Enter format, 3 4, for example.\nEnter 99 99 to end entries.\n";
//input of values
cin.ignore(4);
int m=0;
do
{
cin>>input[m][m];
m++;
if(input[m][m]!=99,99)
break;
}while(m<20);
/*
while(input[m][m]!=99,99)
{
cin>>input[m][m];
m++;
}
/*
for(int m=0;m<INT_MAX;m++)
{
cin>>input[m][m];
if(input[m][m]==99)
break;
}
*/
//input array indexing
//output array
cout<<"\n\n\n";
cout<<"\t\t\t\t\t\t\t\t\t\t\t\t\tColumn\n\n";
for(columns=1;columns<21;columns++)
{
cout<<"\t"<<columns;
}
cout<<"\n\n\n";
for(int i=0;i<20;i++)
{
cout<<"Row "<<i+1<<"\t";
cout<<endl;
for(int n=0;n<20;n++)
{
cout<<input[i][n]<<"\t";
}
cout<<endl;
}
cin.get();
cin.get();
return 0;
}

Answer 1

if(input[m][m]!=99,99)
your input is an array of int, 99,99 is not an int. use valid int value, 5555 for example, or simple 99

Answer 2

E.g)
#include <iostream>
#include <iomanip>
#include <utility>
#include <vector>
#include <iterator>
using namespace std;
const size_t size=20;
char table[size][size];
void table_clear(void){
for(int v = 0; v<size; ++v)
for(int h = 0; h<size; ++h)
table[v][h]=' ';
}
void table_put(pair<int, int> p){
int v = p.first;
int h = p.second;
table[v-1][h-1] = '*';//to zero origin
}
void table_disp(){
cout << " ";
for(int i=0; i<size;++i){
cout << setw(3) << i + 1;
}
cout << "\n" << endl;
for(int i=0;i<size;++i){
cout << setw(3) << left << i + 1;
for(int j=0;j<size;++j){
cout << setw(3) << right << table[i][j];
}
cout << endl;
}
}
int main(){
vector<pair<int,int> > v;
pair<int, int> end(99,99);
pair<int, int> rc;
cout << "Enter each cell in first colony use row space column Enter format, 3 4, for example.\n";
cout << "Enter 99 99 to end entries." << endl;
while(true){
int row, column;
cin >> row;
cin >> column;
rc = make_pair(row, column);
if(rc == end)
break;
v.push_back(rc);
}
table_clear();
for(vector<pair<int,int> >::const_iterator iter = v.begin();iter != v.end(); ++iter ) {
table_put(*iter);
}
table_disp();
}
