Please explain what is going on here.

Say you have a file named "myfile" that initially contains the following data: Have a great summer vacation. What does the following program print? int main() {char ch; FILE *fp; fp = fopen("myfile", "a"); fprintf(fp, " Bye."); fclose(fp); fp = fopen("myfile", "w"); fprintf(fp, " Just kidding."); fclose(fp); fp = fopen("myfile", "r"); while ((ch = fgetc(fp)) != EOF) fprintf(stdout, "%c", ch); fclose(fp); return 0;} Have a great summer vacation. Bye. Just kidding. Have a great summer vacation. Just kidding. Have a great summer vacation. Bye. Just kidding. This program doesnt actually compile.

Explanation / Answer

Initially a file pointer is declared

opening a file in append mode does nothing

The content remains as it is

But when the file is opened in write mode.the existing data is overwritten then the content is "Just Kidding"

In 3rd case the data in file is read ,hence the answer is option 4
