how to reset to read from beginning of file c

Resetting to Read from Beginning of File in C

To reset the file pointer to the beginning of a file in C, you can use the fseek function. Here are the steps to achieve this:

1. Open the File: First, open the file in read mode using the fopen function.

2. Use fseek to Reset: Use the fseek function to move the file position indicator to the beginning of the file. The syntax for fseek is: c fseek(filePointer, 0, SEEK_SET);

This line of code sets the file position indicator to the beginning of the file.

1. Close the File: After resetting the file pointer, close the file using the fclose function to release the resources.

Here's an example of how the code might look:

#include <stdio.h>

int main() {
    FILE *filePointer;
    filePointer = fopen("example.txt", "r");

    // Check if the file was opened successfully

    fseek(filePointer, 0, SEEK_SET);

    // Read from the beginning of the file

    fclose(filePointer);

    return 0;
}

This code opens a file called "example.txt", resets the file pointer to the beginning, and then closes the file [1].
