Write a program to model a simple calculator. Each data line should consist of the next operation to be performed from the list below and the right operand. Assume the left operand is the accumulator value (with an initial value of 0). You need a function scan_data() with two output parameters that returns the operator and the right operand scanned from the data line. You need a function do_next_op() that performs the required operation. do_next_op() has two input parameters (the operator and the operand) and one input/out put parameters ( the accumulator). The valid operators are:
+ add
- minus
* multiply
/ divide
^ power(raise left operand to power of right operand)
q quit
Your calculator should display the accumulator value after each operation.
Sample run:
Calculator program ( RESULT=0)
Input: + 5.0
Result:5.0
Input: ^ 2
Result:25.0
Input: / 2
Result:12.5
Input: q
Final Result:12.5
I don't know how to make it..can any one help?? or a clue??
