I'm just trying to get fscanf to read all the characters in a file, along with all the words, but whenever I try to run a whileloop on the file I opened twice it doesn't seem to work? It only seems to be able to use fscanfon a file one time. I found a work around where I can scan the same file twice except I need to open the file a 2nd time for this to work. How can I use fscanf on the same instance of a file twice?
/*Description: Program will open a file named Story.txt
then counts the number of words and characters
and prints them out */
int main(){
char word[225]; // will be used to hold words (array of chars)
char c; // will be used to hold chars
int wordCount = 0; // will be used to hold the number of words in the file
int charCount = 0; // will be used to hold the number of chars in the file
FILE* wordFile = fopen("Story.txt","r"); // opens the file Story.txt for counting words
printf("Words: "); // indicates that the following outout will be the words of the file
while(fscanf(wordFile,"%s",&word)==1){ // a loop to scan the file for all the words in it until the end of the file
printf(" %s ",word); // prints out the word in the given cycle
wordCount = wordCount + 1; // keeps count of the words the loop has scanned up till now
}
fclose(wordFile); // closes wordFile and frees the memory
FILE* charFile = fopen("Story.txt","r"); // opens file Story.txt for counting chars
printf("\n\nChars: "); // indicates the following output will be the chars of the file
while(fscanf(charFile,"%c",&c)==1){ // a loop to scan the file for all the chars in it until the end fot he file
if(c!=' '){ // will check if the char is a space, if it is it will not count it
printf(" %c ",c); // prints out the char for the given cycle
charCount = charCount + 1; // keeps count of the chars the loop has scanned up till now
}
}
fclose(charFile); // closes charFile and frees the memory
printf("\n\nWord count: %d and Char count: %d",wordCount,charCount-1); // prints out the word count and char count
return 0;
}
As you can see i have to create two instances of the file or else it will not work. The first instance is called wordFile and the 2nd instance is called charFile. Here's the thing though: Both loops work, it's just that I can't use them on the same file twice. How can I make it so that I will only need to open one instance of the file and then use it to count both the words and the chars in it?
Things I tried: adding the space as suggested here didn't work: C: Multiple scanf's, when I enter in a value for one scanf it skips the second scanf (i searched fscanf but scanf is all that came up so i went off of that).
Another work around that I found strange: if i use wordFilein the 2nd while loop to search for chars it works, the only problem is I have to declare fclose(wordFile); right before it's used in the while loop. I thought fclosewas suppose to close the file and make it unusable? Anyways that worked but what I really want is to use use one instance of the file to read all the chars and strings in it.
