Need help to get this program work correctly.

[niifelix]

I am new to programming and writing a C Program to count words, characters and newlines. I came up with this code and like to know people opinion on it. I have written the same program using the do-while but unfortunately I am not getting the desired result. Please I will be grateful for any help to rectify the problem.

While Loop Version

 // counts characters, words, lines 
 
#include <stdio.h> 
#include <ctype.h>         // for isspace() 
 
int main(void) 
 
{ 
   char c;                 // read in character 
 
    long n_chars = 0L;      // number of characters 
 
    int n_lines = 0;        // number of lines 
 
    int n_words = 0;        // number of words 
 
   int inword = 0;         // == true if c is in a word 
 
    printf("Enter text to be analyzed (return then Ctrl+Z to terminate):\n\n"); 
 
 
    while ((c = getchar()) != EOF) 
 
    { 
 
        n_chars++;          // count characters 
 
        if (c == '\n') 
 
            n_lines++;      // count lines 
 
        if (!isspace(c) && !inword) 
 
        { 
 
            inword = 1;  // starting a new word 
 
            n_words++;      // count word 
 
        } 
 
        if (isspace(c) && inword) 
 
            inword = 0; // reached end of word 
 
    } 
 
    printf("characters = %ld, words = %d, lines = %d, \n", n_chars, n_words, n_lines); 
 
    return 0; 
}

Do-while Loop Version returns more than expected number of words and characters

// counts characters, words, lines 
 
#include <stdio.h> 
#include <ctype.h>         // for isspace() 
 
int main(void) 
 
{ 
   char c;                 // read in character 
 
    long n_chars = 0L;      // number of characters 
 
    int n_lines = 0;        // number of lines 
 
    int n_words = 0;        // number of words 
 
    int inword = 0;         // == true if c is in a word 
 
    printf("Enter text to be analyzed (return then Ctrl+Z to terminate):\n\n"); 
 
 
  do 
 
    { 
      c = getchar(); 
        n_chars++;          // count characters 
 
        if (c == '\n') 
 
            n_lines++;      // count lines 
 
        if (!isspace(c) && !inword) 
 
        { 
 
            inword = 1;  // starting a new word 
 
            n_words++;      // count word 
 
        } 
 
        if (isspace(c) && inword) 
 
            inword = 0; // reached end of word 
        
    } 
 
    while (c != EOF); 
 
    printf("characters = %ld, words = %d, lines = %d, \n", n_chars, n_words, n_lines); 
 
    return 0;
