The main differences between fread and fwrite in the C language lie in their functionality and usage when it comes to file operations.<\/p>\n

    \n
  1. fread is used to read data from a file and store it in a specified memory location, with the following prototype:<\/li>\n<\/ol>\n
    size_t<\/span> fread<\/span>(void<\/span> *ptr, size_t<\/span> size, size_t<\/span> nmemb, FILE *stream)<\/span>;\r\n<\/code><\/pre>\n
    ptr is the memory address where the data is stored, size is the size of each element, nmemb<\/a> is the number of elements to be read, and stream is the file pointer.<\/p>\n
      \n
    1. The function fwrite is used to write data into a file, with the following prototype:<\/li>\n<\/ol>\n
      size_t<\/span> fwrite<\/span>(const<\/span> void<\/span> *ptr, size_t<\/span> size, size_t<\/span> nmemb, FILE *stream)<\/span>;\r\n<\/code><\/pre>\n
      In this case, ptr is the memory address of the data to be written, size is the size of each element, nmemb is the number of elements to be written, and stream is the file pointer.<\/p>\n
      In general, fread is used to read data from a file, while fwrite is used to write data to a file. Their functions are opposite of each other, but their usage is similar.<\/p>\n
