/* Explaination  */
/* This program will help to count number of words in a line.
  for(l=0;a[l]!='\0';l++) is used to  calculate total number of characters. Its will help in Space checking condition in next loop. The condition  if(a[i]==' ' && a[i+1]!=' ')  is taken because if there are two spaces between two words then it will take it only as one space rather taking two space*/
