C++

die's job is to output an error message alarmingly and terminate the program. You may copy my

function definition, or use your own:

// The following 4 lines should be present if we have a die function:

#include // cout, endl

#include // string

#include // exit, EXIT_FAILURE

using namespace std;

bool die(const string & msg){

cout <<"Fatal error: " <

exit(EXIT_FAILURE);

}

3. This program's job is to input a mathematical expression and output the answer.

A valid expression is an int (possibly negative); an operator, which must be one of

* / % + - ; and another int. For example,

12 + -3

is a valid expression by these rules. An additional restriction is that if operator is / or %, then the

second operand may not be 0.

If the expression doesn't abide by these rules, c&d. If it's ok, then output the equation that

equates the expression with the answer.

For full credit, use a switch statement based on the operator

A run of your program might go as

gimme an expression:

19 % 5

19 % 5 == 4
