Help for another program

Because I'm nice and its due tomorrow, here's part of my code:

while( i < sent.size() )
    {
        switch( sent[i] )
        {
            case 'a':
            acount++;
            break;
        }    
         
        i++;
    }

And to only show the letters that actually appear more than 0 times:

    if( acount )
        cout << "a = " << acount << endl;

[Androto]

how would i use that in the code?

[gamehead200]

See the acount++? You need to create an integer with the name acount (or whatever your letter is) and set it to 0... Once it finds the letter a in your sentence, it will add 1 to acount... sent is the variable I used for the sentence... You need to create a whole bunch of cases for each letter as well... For the second piece of code, you need to repeat that for each letter as well!

[Androto]

what is switch?

WHAT IS WRONG WITH THIS? I GOT LIKE OVER 107 MISTAKES. I'M SURE THERES JUST ONE LITTLE THING I DID WRONG WHICH MADE THE REST OF IT WRONG.

Deleted (i didn't want to triple post)

Hey relax. I'm right here. Relax. And come back in an hour or so. It's late and I am busy with stuff, but also doing your homework. Just relax.

[Androto]

lol. k, i'll be back

[Valmont]

Give this to your teacher. I don't think you'll understand everything although I did my best to keep it simple and straightforward. Just ask what you want to know.

By the way, I needed to split up theAlphabet initialization because something goes wrong with copying to this board. But you can make it just one line, or leave it like this.

#include <iostream>
#include <string>

using namespace std;

//Optional function: depends on IDE.
void wait_for_enter();

//The world we are talking about.
const unsigned CHARS = 52;
string theAlphabet = "abcdefghijklmnopqrstuvw"
   "qyzABCDEFGHIJKLMNOQRSTUVWXYZ";
unsigned theAlphabetCount[CHARS]={0};
string sSentence;

//Core functions. 
void menu();
void count_chars();
void print_stats();

int main()
{
   menu();
   count_chars();
   print_stats();
   
   wait_for_enter();
   return 0;
}

////////////////////////////////////////////////

void wait_for_enter()
{
  cout << "press <enter> to continue...";
  // Reset failstate, just in case.
  cin.clear();
  string line;
  getline( cin, line);
}

/////////////////////////////////////////////////

void menu()
{
   cout<<"Enter a sentence please (CTRL-Z/D to abort):"<<endl;
   while( !(getline(cin, sSentence)) || sSentence.size()==0 )
   {
      //If CTRL-Z/D then exit: we don't want to enter anything.
      if(cin.eof())
         break;
      cout<<"Something went wrong, or you didn't enter a sentence. Please try again."<<endl;
      //Just in case.
      cin.clear();
   }
}

/////////////////////////////////////////////////

void count_chars()
{
   for(unsigned i=0; i<sSentence.size(); ++i)
      for(unsigned j=0; j<CHARS; ++j)
         if( sSentence.substr(i,1) == theAlphabet.substr(j,1) )
            theAlphabetCount[j]++;
}

//////////////////////////////////////////////////

void print_stats()
{
   cout<<"\t\tTHE STATISTICS"<<endl<<endl;
   cout<<"\t\t--------------"<<endl<<endl;
   cout<<"\t\tAnalized sentence: "<<sSentence<<endl<<endl;
   cout<<"\t\tChar:\tCount:"<<endl;
   
   for(unsigned i=0; i<CHARS; ++i)
      if(theAlphabetCount[i] > 0)
         cout<<"\t\t"<<theAlphabet[i]<<"\t"<<theAlphabetCount[i]<<endl;
}

THX ALOT!!!!

[Valmont]

I've improved it (very slightly), just a heads up. But that is not why I am replying.

You should tell your teacher that you did get considerable help. Not only from me, but gamehead gave you a critical hint as well! Otherwise your rating won't be fair compared to others.

gamehead200
See how I avoided a long switch statement and millions of variables?

[Androto]

ok, i don't think he's online this late at night, but who knows, i'll tell my teacher and gamehead200 tomorrow morning.

i have a couple of questions:

unsigned theAlphabetIndex[52]={0};
can you explain this, didn't you just difine this in the line before?

why are you using void? what does void mean? does it mean it doesn't return a number?

[Androto]

one more thing, the ctrl-d or ctrl-z thing doesn't work, but when i hit enter it works fine

[Androto]

while( !(getline(cin, sSentence)) || sSentence.size()==0 )

i don't understand this part
