#include"iostream.h"

void main()
{
 char a[100];
 int i=0,j=0,n[10],wn=0,count=0,n1[10] = {0,0,0,0,0,0,0,0,0,0},n2;
 clrscr();
 printf("\n PLEASE END THE STRING BY USING ( . ) SYMBOL TO GET THE CORRECT OUTPUT\n\n   ");
 gets(a);
 while(a[i] != '\0')
 {
  if(a[i] == ' ' || a[i] =='.')
  {
   n[j] = i-wn;
   wn = i+1;
   j++;
   count++;
  }
  i++;
 }

 cout <<"\n NUMBER OF WORDS : "<<"\n";

 for(i=0;i < count;i++)
 {
   n2 = n[i];
   n1[n2]++;
 }

 for(i=1;i < 10;i++)
 {
  cout << "\n NUMBER OF "<<  i <<" LETTER WORD : " <
 }
 getch();
}
