I want to be able to read a specific line from a file in C++. I currently have a program that goes like this: char name[20]; int main(int argc, char *argv[]) { cout << "Please enter your name: "; ofstream examplefile ("example.txt", ios::out | ios::trunc); cin.getline (name, 20); examplefile << name; examplefile.close(); return 0; } And so far, it compiles fine but I want to be able to read and write to a specific line in the text document. Such as when the user enteres their name it would be written to line 2 instead of the top line and then I would like to be able to read from line 2 specifically later on in the program. Please help!

You are actually asking for a database solution with a table and an index. The next question is, if you are going to use a fix or variable record length and how do you map the name to get an unique index. If that's all too complicated, you may just want to stick with with your sequential search.

someone told me a question that make a C++ program in which user can read the data from data in file,whose first line has an integer value that show that how many next line s you have to read.And every line has two integer values and display,you have to find the maximum of those,both values and display the input values and the maximum of both.
