C Language K&r Exercise series--the number of letters per word in a statistical document, output in histogram form

Original question:

Write a program to print ahistogram of the lengths of words on its input. It's easy-to-draw thehistogram with the bars horizontal; A vertical orientation is more challenging.

This is my first hundred lines of code (with comments, spaces, etc.)

Main two parts: input and output

#include  < stdio.h > #define  MAXWORDLEN 10main  ( void ) {int  C;int wordlen = 0;int thisidx = 0;long lengtharray[maxwordlen + 1 ];long thisval = 0;long maxval = 0;//initializeint inspace = 0; int firstletter = 1;int done = 0;for  ( thisIdx = 0;  thisidx <= maxwordlen; thisidx++ ) {lengtharray[thisidx] = 0;} while  ( done == 0 ) {C = getchar ();if  ( c ==  '   ')  | |  c ==  ' \ n '  | |  c ==  ' t '  | |  c == EOF ) {if  ( inspace == 0 ) {Inspace = 1;firstletter  = 0;if ( wordLen <= MAXWORDLEN ) {Thisval = ++lengtharray[wordlen  - 1];if ( thisVal > maxVal ) {maxval  = thisval;}} Else{thisval= ++lengtharray[maxwordlen];if ( thisVal > maxVal ) {maxval =  Thisval;}}} if  ( c== EOF ) {done = 1;}} else{if  ( inspace == 1 | |  firstLetter == 1 ) {wordlen= 0;inspace= 0;firstletter = 0;} ++wordlen;}}

Then the output section

for  ( thisVal = maxVal; thisVal > 0; thisVal-- )        {            printf  (   "%4d  |", thisval );             for  ( thisidx = 0; thisidx <= maxwordlen; thisidx++  )             {                   if  ( lengtharray[ thisidx] >= thisval )                    {                         printf  (  " *   " ";                   }                   else                   {                          printf  (       );                   }             }                   printf  (  "\ n"  );      }             printf  (  "       |_ " ) &NBsp;     for  ( thisIdx = 0; thisIdx <=  maxwordlen; thisidx++)       {             printf  (  "___"  );      }       printf  (  "\n      "  );       for  ( thisIdx = 0; thisIdx < MAXWORDLEN;  thisidx++ )       {             printf  (  "%3d", thisidx + 1 );       }      printf  (  "  >\n"  );       for  ( thisIdx = 0; thisIdx < MAXWORDLEN + 2;  thisIdx++ )       {            printf  (   "   "  );      }       printf  (  "  %2d\n", maxwordlen );}
