    char content[1000];
   
    
    fptr = fopen("sample.txt", "w");
    if (fptr == NULL)
    {
       printf("Cannot open file \n");
       return 0;

Explanation

fopen() to open the specified file. "sample.txt" is file name. "w" denotes open it in write mode and earse the existing content. So write operation starts from begning.

Fprintf() writes the content into the file.


Note: sample.txt should exsist  in the same folder where your program is located.
