Question

in c++ using repl.it only

Problem 3 : C++, using repl.it for coding ONLY answer, but sure leave to leave comments every two lines explaining what the codes mean as you go along (a) Write program that prompts the user to enter the number of columns and rows in a grid. The program should print out a seating chart with the desired grid dimensions. The seating chart should be numbered starting at 1 in the top left corner. Codecheck How many columns? 3 How many rows? 2 1 2 3 4 5 6

Answer 1

Please let me know if anything is required.

Problem 1:

Copyable code:

#include <iostream>

using namespace std;

int main()
{
cout<<"How many columns?\n"; //taking number of rows input from the user
int cols;
cin>>cols;
  
cout<<"How many rows?\n"; //taking number of columns input from the user
int rows;
cin>>rows;
  
cout<<"\n"; //printing thr new line
int k=1;
for (int i=0;i<rows;i++) //printing the seating chart
{
for(int j=0;j<cols;j++)
{
cout<<k<<" ";
k++;
}
cout<<"\n";
}
  

return 0;
}

Sample output:

How many columns? 3 How many rows? 2 1 2 3 4 5 6

Problem 2:

Copyable code:

#include <iostream>

using namespace std;

int main()
{
  
cout<<"How many rows?\n"; //taking number of columns input from the user
int rows;
cin>>rows;
  
cout<<"\n"; //printing thr new line
int k=1;
for (int i=0;i<rows;i++) //printing the triangular seating chart
{
for(int j=0;j<i+1;j++)
{
cout<<k<<" ";
k++;
}
cout<<"\n";
}
  

return 0;
}

Sample output:

How many rows? 4 1 2 3 4 5 6 7 8 9 10
