Q3. Write a simple calculator program calc.c, that prompts the user a first operand, an operator, and a second operand, then computes the result. Use a switch statement to decide whether to perform addition, subtraction, multiplication, or division based on the operators +,, or / characters. Hint: the argument of the switch statement, the operator, is a character data type (char). Sample output: Enter x, operator, y:12+30 12.000000+30.000000=42.000000 Enter x, operator, y:53 5.0000003.000000=15.000000 Enter x, operator, y:53 > 5.0000003.000000=15.000000 Enter x, operator, y:7 / 2 7.000000/2.000000=3.500000 Enter x, operator, y:12 / 0 can't divide by 0 , buddy! Enter x, operator, y:12 \& 6 Invalid operator
