Write a C++ program that outputs appropriate messages for matching grouping symbols in an arithmetic expression.

Write a C++ program that outputs appropriate messages for matching grouping symbols, such as parentheses and braces, in the input arithmetic expression. For example, the expression "{25+(3-6)*8}" contains matching grouping symbols (curly braces and parentheses), while in case of "[25+{3-6)*8]" only matching grouping symbols a ...continues
