problem with switch case

in making menu option using switch case when i should use getchar?
i make an option menu that ecpect interger from user but when i enter char or word
the program will print the menu and it become infinite loop. How to solve that problem ?
thank you

I think I know what you are talking about but the old give a fish or teach to fish so first I'll show you my fish.

fish one
fish two
fish three

I found these by grabbing some lures and using the mighty "search" as a pole.

A good method is to look at your question and find the words that seem to be valid to you. Just plunk them in the search dialog. Lots of fish there (and them's good eatin') just swimming around.

Another good method is to troll the forum by setting the "show past 45 days" to "show since the beginning" and read the thread titles. I know there are some that talk about just what you are talking about.

GIDForums uses google to search this site and you get results quickly with the word+word+word method. If that doesn't work, post some of your code and describe your problem in a little more detail. (me, I like to 'cast' into the waters until I snag something)

Sorry about all the fishing analogies but I missed trout season this year and have to wait until spring.

Seriously, you will get better help (from the smart people here instead of me) if you post your code and some example input.

I know it is a simple standard question then sorry if i posted too many lines here but i'm just a newbie :-)
my problem is in the main file:

CPP / C++ / C Code:

#include "text.h"
extern address FirstAvail;
int main()
{	Tabtext Tab;
	int pilihan; 
	int Nbfound=0,i=0,quit=0;
	int j=1;
	int foundline[20];
	int k;
	Kata search;
  do{	
	printf("============MENU============\n");
	printf("1.Input Text\n");
	printf("2.View Text\n");
	printf("3.Count word\n");
	printf("4.Count letter\n");
	printf("5.Count Line\n");
	printf("6.Search word \n");
	printf("7.Keluar\n");
	printf("============================\n");
	printf("Input pilihan:\n");
	scanf("%d",&pilihan); 
		switch(pilihan){
			case 1: printf("Input text end it with # \n");
					GetText(Tab);
				break;
			case 2: PrintText(Tab);
				break;
			case 3: printf("Nb Kata  = %d\n",CountKata(Tab));
			        getch();
				break;
			case 4: printf("Nb huruf = %d\n",CountHuruf(Tab));
			        getch();
				break;
			case 5: printf("Nb baris = %d\n",CountLine(Tab));
				getch();
				break;
			case 6: printf("Input word:\n");
				scanf("%s",&(search.TKata));
				getLen(&search);
				SearchKata(search,Tab,foundline,&Nbfound);
				printf("\n found %d in: \n",Nbfound);
				while(foundline[i]!=-99){
				   if (foundline[i]==foundline[i+1]){
				   	k=i;
					while(foundline[k]==foundline[i+1]){
						j++;i++;
					}
					printf("%d word in line %d\n",j,foundline[i]);
					j=1;
				    }
				    else{if(foundline[k]!=foundline[i])
				    	printf(" 1 word in line %d\n",foundline[i]);
				    	i++;
				    }
				}
				break;
			case 7: printf("Exit\n");
				quit=1;
				break;	
			default: printf("unknown option\n");	
				 break;		
		}
		 
	}
   	while(quit==0);
	return 0;
}

i forget to delete (in text.h)
extern address FirstAvail;

another question
this is out of topic with previous question
why if changed

CPP / C++ / C Code:

int IsEQ( Kata T1, Kata T2)
{     
  int i = 0;
  if (T1.len !=  T2.len) return(0);
  else{
    for (i=0;i < (T1.len);i++ ) {
    if   (T1.TKata[i] != T2.TKata[i]) 
         return (0);
    }
    return(1);
       
            }
}

with this function my SearchKata function not work?
Whats wrong in this second function?

CPP / C++ / C Code:

int IsEQ( Kata T1, Kata T2)
{     
	int i = 0;
	int found = 1;
	if (T1.len !=  T2.len) {found = 0;}
	else
	{
		while (i < (T1.len) && found == 1)
	  {
		if   (T1.TKata[i] != T2.TKata[i]) 
		     {found = 0;}
		else {i++;}
		
	  }	           
        }
	return found;
}
