Substitute string with file
I wrote the following code:
Code:
#include "stdafx.h"
#include "string.h"
#include "ctype.h"
int count_nonspace(const char* str)
{
int count = 0;
while (*str)
{
if (!isspace(*str++))
count++;
}
return count;
}
int _tmain(int argc, _TCHAR* argv[])
{
int a[127];
int i = 0, j = 0, count[127] = { 0 };
int cur_count = 1; /* Gets compared with value in count[] */
char cur_char = '\0';
char string[100] = "Hellooooo world";
for (i = 0; i < strlen(string); i++)
{
if (cur_char == string[i])
{
cur_count++;
}
else
{
if (32 < cur_char && cur_char < 127)
{
if (cur_count > count[cur_char])
{
count[cur_char] = cur_count;
}
}
cur_char = string[i];
cur_count = 1;
if (32 < cur_char && cur_char < 127)
{
if (!(count[cur_char]))
{
count[cur_char] = cur_count;
}
}
}
}
/* Find the most consecutive char and print it. */
char max_char = '\0';
int max_count = 0;
for (j = 0; j < 127; j++)
{
if (max_count < count[j])
{
max_count = count[j];
max_char = j;
}
}
printf("%c\n", max_char);
}
This program is checking how many times each character appears in a row but it uses string as a source of a text and i want to use a file. I am not very fluent in operating on files, thus my question is what should be change in this program to make it work on files, not only on strings?
