C++ :: Add Additional Switch Statement That Allows For Passing Option For A Grade

Remove the break statements from each of the cases. What is the effect on the execution of the program?
Add an additional switch statement that allows for a Passing option for a grade of D or better. Use the sample run given below to model your output.

Sample Run: What grade did you earn in Programming I ? A YOU PASSED! an A - excellent work!

Rewrite the program LastFirst_lab44.cpp using if and else if statements rather than a switch statement. Did you use a trailing else in your new version? If so, what did it correspond to in the original program with the switch statement?

// This program illustrates the use of the Switch statement.
// The break statement causes all subsequent expressions to be executed as well, also known as "falling through".
// The trailing else statement acts just like the default section if none of the options from before work it gets "defaulted" to it.

#include <iostream>
using namespace std;
int main() {
char grade;
cout << "What grade did you earn in Programming I ?" << endl;

[code]....

how do you add an additional switch statement? i tried multiple times and i'm not sure if i don't understand braces enough but it didnt seem doable. also, I'm not sure what the teacher wants me to submit.
