Question

Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Use separate print statements to print the row and column. Ex: numRows = 2 and numColumns = 3 prints:

Answer 1

Step by step explanation along with C++ code is provided below.

C++ Code:

#include <iostream>

using namespace std;

int main()

{

int numRows;

int numCols;

int r = 1;

cout <<"Please enter no. of rows"<<endl;

cin>>numRows;

cout <<"Please enter no. of columns"<<endl;

cin>>numCols;

cout<<"Seating arrangement in the theater:"<<endl;

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

{

char c = 'A';

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

{

cout <<r << c << " ";

c= c + 1;

}

r= r + 1;

}

return 0;

}

Explanation:

// the outer loop prints the rows

// counter r = r + 1 increments the rows

// the inner loop prints columns

// counter c = c + 1 increments the columns

// int r = 1 ensures that rows starts from 1

Output:

The program is tested multiple times and is working correctly for any number of rows and columns

Please enter no. of rows

2

Please enter no. of columns

3

Seating arrangement in the theater:

1A 1B 1C 2A 2B 2C
