C++ Define an "Expression" class that manages expression info: operand1 (integer), operand2 (integer), and the expression operator (char). It must provide at least the following method:- toString() to return a string containing all the expression info such as        50         +        50        =         100 Write a command-driven program named "ListExpressions" that will accept the following commands:add, listall, listbyoperator, listsummary, exit "add" command will read the expression and save it away in the list "listall" command will display all the expressions "listbyoperator" command will read in the operator and display only expressions with that given operator "listsummary" command will display the total number of expressions, the number of expressions for each operator, the largest and smallest expression values "exit" command will exit the program Requirements:- It must be using the array of pointers (not vector) to Expression objects to manage the list of Expression…
