Hello,

How can I do this :

Modify the program and use the strtok function to count the number of words in the entire book “Robinson Crusoe”.

I have already store the book in the file (defoe-robinson-103.txt),

Here is the code:

#include
#include

#define MAX 4000
int main(void)
{
int count = 0;
FILE* bkPtr;
char buffer[MAX];
fopen_s(&bkPtr, "defoe-robinson-103.txt", "r");
if (bkPtr == NULL)
{
puts("cannot open the file");

}
else
{
while (fgets(buffer, MAX, bkPtr))
{
puts(buffer);
}
fclose(bkPtr);
}

}
