- This program is a simple calculator that performs addition, subtraction, multiplication, and division of two floating-point numbers A and B.
- The program starts by including the standard input-output library "stdio.h" and declaring the main function.
- It then prints the title "Calculator" and a line of equal signs for decoration.
- Two float variables, a and b, are declared to store the user inputs for the calculation.
- The program prompts the user to enter the value of A and B through standard input using scanf.
- The program then prints the result of addition, subtraction, multiplication, and division of A and B using printf.
- The program ends by returning 0 to indicate that it has executed successfully.
