C programming question (-:?

Question

hi! is this valid?

switch 'A': printf("something"); break;

(coz i have doubts with the 'A' part...)

thanks a lot!

Answer 1

No it should be something like

switch(ch)

{

   case 'A':

        printf("something");

        break;

}

ch is a character variable.

Answer 2

It should be

switch(variable)

case 'A':

printf("something");

break;

Answer 3

no

Answer 4

No, that is not the correct usage. The correct usage would be:

int main(){

char smthng;

cout << "What letter will you choose? (a-c): ";

cin >> smthng;

switch(smthng){

case 'a': printf("You chose the letter A"); break;

case 'b': printf("You chose the letter B"); break;

case 'c': printf("You chose the letter C"); break;

}

}

Always remember the very important "break;". otherwise, the switch statement will just choose the last thing in there.

Answer 5

There is a syntax error in it for sure, and whenever u have doubt then check the program by running it, purchase C language book by Robert Lafore this is the best book on C language.
