Help with section of code.

I need some help with my code.

How can I allow the player to guess the word if they'd want to, instead of going through and guessing letters when they already know the word.

Code:

#include <iostream>
#include <cstdlib>
#include <fstream>
#include <string>
#include <cmath>

using namespace std;

void type_of_word(char f);


int main()
{   
		char c, ch, ch1, ch2;

		char word[50];

		char word1[25];

		int l, i, next_guess, n, m, x;

		do

		{  
			do

			{

			cout<<"\n\n\n\t******************************************  **************\n";

			cout<<"\t********************* WoRd GuEsSeR *********************\n";

			cout<<"\t************************************************  ********\n\n\n";

			cout<<"\n \t(E) Enter your own word\n\n \t(C) Computer Chosen Word @ Random\n\n \t(Q) Quit\n\n\n Enter your choice: ";
			
			cin>> ch2;

			}
		
		while	(ch2 != 'C' && ch2 != 'c' && ch2 != 'E' && ch2 != 'e' && ch2 != 'Q' && ch2 != 'q'&& ch2 != 'A' && ch2 != 'a');
		
		if	(ch2 == 'Q' || ch2=='q')  exit (0);

		if	(ch2 == 'C' || ch2=='c')

		{
			ifstream fin("words.txt");
			
			if	(!fin) 
			
			{ 
			
			cout<<"\n\nYou are missing a file called words.txt\n\n"; 
				
			return 0;
			
			}
			
			for (i=0;!fin.eof();i++)   fin.getline(word,25);
			
			fin.close();

			do 
			
			{
			
			x=rand();
			
			}
			
			while(x>i || x<0);

			ifstream finn("words.txt");
			
			for (i=0;!finn.eof();i++)

			{finn>>c; finn.getline(word,25); if (x==i) break;}

			finn.close();
		}

		if	(ch2 == 'E' || ch2=='e')
		
		{
			
		cin.get();

		cout<<"\tType the word :  ";

		cin.getline (word, 25);
		
		}
		
		if	(ch2 == 'E' || ch2=='e' || ch2 == 'C' || ch2=='c')
		
		{
			l=strlen(word);

			char choosen[50]="\0";

			n=0; 
			
			m=0;

		for	(i=0; i<=24; i++)
		{
			if (word[i]=='\0') {word1[i]='\0'; break;}

			if (word[i]==' ')  {word1[i]=' ';  n++;}

			if (word[i]!=' ')  word1[i]='-';
		}

		next_guess=l+2-n;     //Guess left, 2 more
		
		do
		{
		
			there:  type_of_word(c);
			
			if (m!=0)  cout<<"\n\n\t\t\tChoosen letters : "<<choosen<<"\n";
			
			cout<<"\n\n\n\t\t\t      "<<word1<<"\n\n\nYou have "<<next_guess<< " guesses left, choose a letter : ";
			
			cin>>ch; cin.get();
			
			for (i=0;i<25;i++) 
				
			if (choosen[i]==ch) 
			
			{
			
			cout<<"\a\t\t     !!You have choosen "<<ch<<" already!!\n"; goto there;
			
			}
			
			next_guess--; 
			
			choosen [m]=ch; 
			
			choosen [m+1]=',';
			
			m+=2;

			for (i=0;i<=49;i++)    
				
			if (word[i]==ch || word[i]==ch+32 || word[i]==ch-32) word1[i]=ch;
			
			if (!strcmpi (word1,word)) {cout<<"\n\t\t\t      "<<strupr(word)<<"\n\n\t\t\tCongratulations, You have won!\n"; break;}

			}
			
		while(next_guess>0 || !strcmpi (word1,word));


		if (strcmpi (word1,word))  cout<<"\nSorry, maybe next time.\n\nThe word was : "<<strupr(word)<<endl;
		
		}

		cout<<"\nWould you like to play again? [Y or N] : ";

		cin>>ch1;  cin.get();

		}
		
			while (ch1=='y' || ch1=='Y');

			system("PAUSE");
			
			return 0;
}

		void type_of_word(char f)

		{   if (f=='p') cout<<"\t\t\t\tPROGRAMMING";
			if (f=='s') cout<<"\t\t\t\tSPORT";
			if (f=='t') cout<<"\t\t\t\tTV SHOW";
		}

you have a terrible syntax young man.
as for guesing : if user knows the word, it wouldn't be a problem for him to "type" it letter by letter.
When i say "type" i mean gues all the letters.

I know that someone can type each letter one by one, but I would want the user to type in the word if he/she would want to guess. Can you elaborate on why my syntax is terrible, I would appreciate it.

example of bad syntax

Code:

			if (choosen[i]==ch) 
			
			{
			
			cout<<"\a\t\t     !!You have choosen "<<ch<<" already!!\n"; goto there;
			
			}

too many empty lines and no clear indentation
try like this instead

Code:

	// some spaces between operators help readability
	if (choosen[i] == ch) 
	{ // no need for a blank line before this
		// break up long lines
		cout << "\a\t\t     !!You have choosen " 
			<< ch << " already!!\n"; 
		
		// one statement on a line!!
		goto there; // also think long and hard before using goto
	}
