File Reader/Writer in C

Below is an example of how you can use C's FileReader and FileWriter to read from and write to a file.

// Include stdio.h
#include 

int main() {
    // Replace "input.txt" and "output.txt" with your file names
    char inputFile[] = "input.txt";
    char outputFile[] = "output.txt";

    // Reading from a file using FileReader and BufferedReader
    FILE *fileReader = fopen(inputFile, "r");
    if (fileReader != NULL) {
        char line[100];

        while (fgets(line, sizeof(line), fileReader) != NULL) {
            printf("Read from file: %s", line);

            // You can process the line as needed here
        }

        fclose(fileReader);
    } else {
        perror("Error reading from file");
    }

    // Writing to a file using FileWriter and BufferedWriter
    FILE *fileWriter = fopen(outputFile, "w");
    if (fileWriter != NULL) {
        // Replace the following line with the content you want to write
        char contentToWrite[] = "Hello, this is written to the file!";
        fprintf(fileWriter, "%s", contentToWrite);

        printf("Write to file: %s\n", contentToWrite);

        fclose(fileWriter);
    } else {
        perror("Error writing to file");
    }

    return 0;
}
