switch statement

[Aaron Knox]

Hi all, I'm still working on my switch statement program (from previous post)thanks to Joaquin my loop is working but for some reason my switch statements are not being activiated. I've included a portion of my code, the switch statements continue for each letter a state begins with (d,f,g,h,i,k,etc) Thanks, Aaron //this program is supposed to read state abbreviations from a file and output the corrosponding state to another file #include #include using namespace std; int main() { ifstream inAbrev("state abs.txt"); //opens the input file ofstream outState("states with abvs.txt"); //opens the output file char firstLetter, secondLetter; inAbrev >> firstLetter >> secondLetter; cout << firstLetter << secondLetter << endl; //just for me to see if anything is happening while(inAbrev) //read til the end of the file { inAbrev >> firstLetter >> secondLetter; cout << firstLetter << secondLetter << endl; switch (firstLetter) { case 'A' : switch (secondLetter) { case 'L' : outState << inAbrev << " is " << "Alabama" << endl; cout << inAbrev << " is " << "Alabama" << endl; //here i'm trying to see if anything is happening break; case 'K' : outState << inAbrev << " is " << "Alaska" << endl; break; case 'Z' : outState << inAbrev << " is " << "Arizona" << endl; break; case 'R' : outState << inAbrev << " is " << "Arkansas" << endl; break; } case 'C' : switch (secondLetter) { case 'A' : outState << inAbrev << " is " << "California" << endl; break; case 'O' : outState << inAbrev << " is " << "Colorado" << endl; break; case 'T' : outState << inAbrev << " is " << "Connecticut" << endl; break; } arrrgh

set the breakpoint on "switch (firstLetter)" line and check the value of firstLetter and secondLetter variables to see what values exactly are in them.

It appears as if nothing is happening because all of your output statements (cout and outState) in your switch statement are wrong. Your doing this: outState << inAbrev << " is " << "California" << endl; cout << inAbrev << " is " << "Alabama" << endl; What this is doing is trying to output the input filestream which, of course, will output nothing. If I read your homework right, you should be doing something like this: outState << firstLetter << secondLetter << " is Alabama" << endl; RageInTheMachine9532

Yep RageInTheMachine is right. none
