Write a program that achieves the same result as the following but uses a C++ switch statement instead. #include
int main()

{
int iNum= 0;
char cLetter= ' ';

std::cout << "Please enter a letter: ";
std::cin >> cLetter < 'c')

if ( cLetter > 'a' && cLetter < 'c')
iNum= 1;

else if ( cLetter== 'd' || cLetter == 'e' || cLetter== 'f')
iNum= 2;
else if (!(cLetter== 'b') && !(cLetter == 'g' && cLetter== 'c')
iNum=3;
else
iNum=4;

std::cout << iNum << std::endl;
system("Pause");
return 0;
