I'm having trouble writing this ARM LEGv8 assembly language program that implements a four-function calculator and prompts the user to enter a pair of decimal integers followed by a character that specifies one of the operators using the scanf feature from the C programming language to read the inputs and printf to display the outputs:

+ for addition to compute A+B

- for subtraction to compute A-B

* for multiplication to produce the product A*B

/ for division to produce the quotient A/B.

Input should be the pair of numbers followed by the operand followed by a return. This should be implemented with scanf.

For example

5 5 + [enter]

The program should display the result by performing the indicated operation on the two input operands A and B and use printf to display it to the user. Only these four operators should be allowed and an attempt to divide by zero should be prohibited.
