C Program to Check Whether Entered String is Keyword or Not?

we know that ANSI C has 32 keyword. actually Keyword are reserved words which predefined in any language. we can not use further these words in program because they have special meaning.if i use these words for our purpose then our compiler get confused to use these words so that we can not use keyword  as variable name and etc.

C Program:

#include<stdio.h>

#include<conio.h>

#include<string.h>

void main()

{

 char keyword[32][10]={"auto","double","int","struct","break","else","long",

       "switch","case","enum","register","typedef","char",

       "extern","return","union","const","float","short",

       "unsigned","continue","for","signed","void","default",

       "goto","sizeof","voltile","do","if","static","while"} ;

char string[10];

 int flag=0,i;

 printf("enter any string:");

 gets(string);

 for(i=0;i<32;i++)

 {

   if(strcmp(string,keyword[i])==0)

   {

     flag=1;

   }



 }



 if(flag==1)

   printf("%s is a keyword",string);

   else

   printf("%s is not a keyword",string);



getch();

}

Output:
