Example Use Case

Need to parse a file path and extract the file name? Or perhaps you want to retrieve specific information from user input? With substring extraction, you can solve real-world problems quickly and effectively.

Sample Code Snippet

cpp

Copy code

#include <iostream>

#include <string>

int main() {

std::string original = "Hello, C++ World!";

std::string substring = original.substr(7, 3); // Extract "C++"

std::cout << "Extracted substring: " << substring << std::endl;

return 0;

}

Why Choose C++?

Efficiency: C++ provides unparalleled performance, ideal for handling large-scale string operations.

Flexibility: The substr() function allows for precise control over which parts of a string to extract.

Versatility: From simple string splitting to complex text processing tasks, C++ has you covered.
