C++ using struct

Write a program, [login to view URL], that uses a struct called block which has three fields: 1. An integer rows 2. An integer cols 3. An character letter A block will be declared and initialized in main. The program should repeatedly read one of the following commands until a q is entered: r: Change the number of rows in the block c: Change the number of columns in the block l: Change the letter in the block a: Change the letter in the block based on an ASCII value p: Print the block in two dimensional format If an illegal command is entered, the program should print an appropriate error message. You are required to write the following six functions: // initializes the block to 4 rows, 4 columns and the // letter * void init_block (block& b); // prompts for and reads a number of rows from the user // and assigns that number of rows to the block void change_rows (block& b); // prompts for and reads a number of columns from // the user and assigns that number of columns to the // block void change_cols (block& b); // prompts for and reads the ASCII value of a character // from the user and sets the letter in the block to // that character void change_ascii (block& b); // prompts for and reads a letter from // the user and assigns that letter to the // block void change_letter (block& b); // prints the block in two dimensional format with a // label void print (block b); The following page shows a sample run of the program (user input in bold). Your program should use the same output formatting.
