Explanation:

Import the required header files like stdio and conio. Any program in C should start with a main(), initialize the variables required for the program, clrscr() used to clear the screen and printf() will display the given message on the display screen. The user input is accepted by a scanf() function and the input is stored in the variables called rows.Logic to print the required output is executed and the output is displayed on the display screen.
