Writing a program using the C++ programming language, through which the program reads a code sentence

The user enters it, and then the program verifies the validity of the sentence, followed by displaying the results. The program determines the priorities in the syntax by automatically putting the brackets in order to specify the priorities in the syntax. Then the outputs are calculated using the stack concept, as shown in the following example:

Entered sentence:

3 + 5 x 7 + 8 - 3

define the priorities:

(((3 + (5 x 7)) + 8) 1)

Here, execution is carried out from the inner arc to the outer arc.

Using the stack concept:

Notes/

1) An addition is made to the stack from the beginning of the arc until reaching the first end of the arc.

2) When the end of the bracket exists, the contents of the stack, the last 3 elements, are unloaded and the process is executed, and it continues until the last bracket in the sentence after prioritizing it.

1- Push 3

2- Push +

3- Push 5

4- Push

5- Push 7

The first end of a parenthesis means to perform the first operation on the last 3 elements entered in the stack

6- Pop 7, Pop x, Pop 5

7- Execute 57

As long as the sentence is not finished, the output is added again to the stack

8- Push 35

The end of a parenthesis means to perform the first operation on the last 3 elements entered in the stack

9- Pop 35, Pop +, Pop 3

10- Execute 38 + 3 = 41

As long as the sentence is not finished, the output is added again to the stack

11- Push 41

12- Push -

13- Push 1

The end of a parenthesis means to perform the first operation on the last 3 elements entered in the stack

14- Pop 1, Pop -, Pop 41

15- Execute 41-1

The sentence ends, so the result is displayed

16- Display 40

The code is clear so that it is applied to the editor

Note: Explanation of the code and that the code works gives correct results
