Question

Given num_rows and num_cols, 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.

Sample output with inputs: 2 3

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

Answer 1

Answer:

Following are the program for the above question in python:

Explanation:

def seat(num_rows,num_cols):#function definition.

   for x in range(1,num_rows+1):#first for loop.

       c='A'

       for y in range(1,num_cols+1): #second for loop.

           print(str(x)+c,end=" ") #print the value

           c=$chr$(ord(c)+1) #expression to form a charater addition.

seat(int(input("enter the number of rows: ")),int(input("enter the number of columns: "))) #take the input from the user.

Output:

• If the user inputs 2 and 3, then the output is :"1A 1B 1C 2A 2B 2C 3A 3B 3C 4A 4B 4C".

Code Explanation :

• The above code is in python language, in which the first line is used to render a message to the user then take the inputs from the user and then pass to the function after converting into int function.
• Then there are two loops in the function which are used to print the number of the seat.
• The first loop is used to print the row number and the second loop is used to print the column number.
