File stream in a particular line in excel

Question

I have a project in which i have to create a student report program. I am storing the data in an excel file.
My problem is, if the user wants to change a particular record, which is at a random line between all the other stored data. How will the file store it back?

so basically, how to bring the 'put' pointer at the start of any particular line?

Answer 1

int i=1;
char line[101];
ifstream imyobj;
imyobj.open(location);
Assume you want to go to 5th line
for(i=1;i<=4;i++)
{
imyobj.getline(sent,101,'\n');
}
Here you got it now imyobj is pointer to nextline at first character.
