C++ using if else statement question?

I have tried to work out this program about 15 times and I keep getting the wrong answer

Using if statements to write a C++ program that inputs a single letter and prints out the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way;

2 = ABC, 3= DEF, 4= GHI, 5= JKL, 6= MNO, 7= PRS, 8= TUV, 9= WXY

No digit corresponds to either Q or Z. For these 2 letters your program should print a message indicating that they are not used on a telephone.


I have tried doing my own program but when I type in a letter other than A B or C, such at D, I get an answer of 2, which is not right, it should print out 3.

Any help would be greatly appreciated!!!! THANK YOU!

char letter;

cout << "Enter a number";
cin >> a;

cout << "The letter is on key "
if(letter == 'a' || letter =='b' || letter =='c')
cout << "2" << endl;
else if(letter == 'd' || letter == 'e' || letter == 'f')
cout << "3" << endl;
else if(letter == 'g' || letter == 'h' || letter == 'i')
cout << "4" <<endl;

and so on....

for those that don't know...

and I made a typo, it's supposed to be:
cin >> letter;
sorry, I went back to change it so it wasn't a=='a' || a =='b' and missed one. Report It

in the if statement u can use the OR condition for eg. if(char==q||char==z){cout<<"these leters are not used on a telefone";} where char is the letter entered by the user....
there are other possibilities too...

no
