Difference Between seekg() and seekp() in C++ File-Handling – Brain Mentors

seekg() and seekp() both are functions of File Handling in C++ and they are very important and useful feature of File Handling in C++. In File Handling of C++, we have two pointers one is get pointer and second is put pointer. They both are used to getting/reading the data from a file and putting/writing the data into a file at particularposition/location. How to use Seekg () seekg() function is used to move/sets the get pointer at the desired/particular position to getting/reading data from a file (External file). If seekg() function is used to move/sets the get pointer at the particular location. So then by using tellg() function we easily get the current position of the get pointer from the external file. Syntax: seekg(offset, direction/seekdir); Using this function the stream pointer is changed the position/location i.e. counting pointer position from the beginning of the file.

How to Index and Slice String in Python?

In Python, Strings are arrays of bytes representing Unicode characters. In simple words, anything that can be described inside single, double, or triple inverted quotes is called String. Creating A String Indexing in String Index is the position which can be used to get a specific Character from the String.Here, Indexing in String starts from 0, then 1 , then 2 , then 3 , then 4 and so on. and if we start from last index of list, then indexing starts from -1, then -2 , then -3 ….so on. Using Index , we can retrieve any character from the String .Now, Element located at nth index can be find by writting list name followed by square brackets, and inside square bracket, we have to write the index for which we want character corresponding to that index. String Slicing String Slicing is the process to make SubString from a given String.
