如何返回传递给函数的行的字符数

Question

我的main.c是调用函数ReadLine（Line）的地方。这是代码......

#include "Definition.h"
#include "ExternalVar.h"
#include <stdio.h>
#include <stdlib.h>

char Line[MaxLine];  /* one line from the file */


int NChars = 0,  /* number of characters seen so far */
    NWords = 0,  /* number of words seen so far */
    NLines = 0,  /* number of lines seen so far */
    LineLength;  /* length of the current line */

int word_count = 0,
    line_count = 0,
    character_count = 0;

extern int Readline(),CountWord(),CountUpdate();

int main(int argc, char *argv[]) {

  FILE *fp;

  fp = fopen(argv[1],"r");
  while(fscanf(fp,"%s",Line) != EOF)
  character_count = Readline(Line);
  printf("character count for this line is : %d  \n",character_count);
    printf("%s\n",Line);
  fclose(fp);      
}

这是Readline.c文件，我的问题是如何进行循环来计算每行的字符数并将值返回给Main.c

#include "Definition.h"
#include "ExternalVar.h"
#include <stdio.h>


int Readline(char *Line) {
  int internal_count = 0;

  for (internal_count = 0; *Line != '\0'; Line++, internal_count++);
return internal_count;
}

这将返回行上的字数而不是字符数。
