output should evaluate all of the expressions and print them each on its own line

the program should read from cin

Write an even better calculator program calc3.cpp that can understand squared numbers. We are going to use a simplified notation X to mean X2. For example, 10 7 -51 should mean 102+7-512 Example: When reading input file formulas.txt 5A; 1000 6A - 5A+ 1; the program should report: $ ./calc3 ? formulastxt 25 1012 A hint: To take into account don't add or subtract new numbers right away after reading them. Instead, remember the number, read the next operator and if it is a ,square the remembered number, then add or subtract it.
