Please edit MY code, to implement the "^" to be able to calculate squares. My code right now can only add and subtract, and is able to identify ";" as the end of a formula and it reads through the redirected file to see if there is more, and prints the sum of each seperate formula. Please see the example in the task description, and use the hint if possible.

Write an even better calculator program calc3.cpp that can understand squared numbers. We are going to use a simplified notation X^ to mean X?. For example, 10^ + 7 - 51" should mean 102 + 7 - 512 Example: When reading input file formulas.txt 5; 1000 + 6" - 5+ 1; the program should report: $ ./calc3 using namespace std; int main() { int s, sum=0; cin>>sum; char op; while(cin>>op>>s) { if(op == ';'){ cout
