Question

after reading what's in the image which  indicates what would be the instructions to follow for the program,  it need to create a c++ program for the following expressions

-(A+B)+(C-D)

-((A+B)+(C-D)

-((A+B)+[C-D])

-((A+B]+[C-D]} 

Steps:
1. Create a Stack.
2. While(end of input is not reached) {
a) If the character read is not a symbol to be balanced, ignore it.
b) If the character is an opening symbol, push it onto the stack.
c) If it is a closing symbol:
i) Report an error if the stack is empty.
ii) Otherwise, pop the stack.
d) If the symbol popped is not the corresponding opening symbol, report an error.
3. At the end of input, if the stack is not empty: report an error.
