Hey,
I am having a problem with file handling.

ofstream myfile("courses.txt");
myfile<<C_Semester.code<<"$" << C_Semester.name<<"$" << C_Semester.Pre_req<<"$" << C_Semester.time<<"$" << C_Semester.fee<<"$";
if(C_Semester.isUnderGraduate==true)
    myfile<<"UnderGraduate$!\n";
else 
    myfile<<"Graduate$!\n";
    for(int k=0;k<i;i++)
        myfile<<temp_store[k];	
        //this overwrites the previous data..Main Problem!
        myfile.close();
        delete[] temp_store;

Why the curose position in the file afer if-else condition of graduate or undergraduate move to beginning and then overwrites the data??

I just tested this (after correcting your errors) and it writes all the data to the file as required. I suspect there is some other code that you are not showing us.

I suspect that you may be running this code multiple times and forgetting that you need to seek to the end every time you open the file. Change the constructor in your code to:

C++

ofstream myfile("courses.txt", ios::app);
