C++ String substr() Substring function is used for handling string operations. It generates a new string with its value initialized to a copy of a sub-string of this object. Syntax : Consider a string 'str', position' pos' and length 'len'. Syntax would be :

28.10.2020 · A part of the string is called substring in C++ and if we want to retrieve a substring from a given string in C++, we make use of a function called substr () function. The substr () function takes the two parameters namely position and length. The parameter position represents the starting position of the substring in the given string.

A substring is a part of a string. A function to obtain a substring in C++ is substr(). This function contains two parameters: pos and len.

The substr () function exists in C++ to generate a new string by cutting a particular portion from a string. The string.h library file is required to include to use this function. This function has two arguments. The first argument contains the starting position of the new string, and the second argument contains the length of the string.
