C 语言文件读写操作

Certainly! In the C programming language, you can perform file read and write operations

using the fopen, fclose, fread, and fwrite functions. Below is a simple example demonstrating

how to read from a file and write to a file in C:

c

Copy code

#include <stdio.h>

#include <stdlib.h>

int main() {

return EXIT_FAILURE;

}

// Open the output file for writing

fileOut = fopen("output.txt", "w");

if (fileOut == NULL) {

perror("Error opening output file");

fclose(fileIn);

return EXIT_FAILURE;

}

// Read from input file and write to output file

fclose(fileIn);

fclose(fileOut);

printf("File read and write operation completed successfully.");
