Reading input line by line is a common requirement in C programming. Thegetlinefunction provides a robust solution for this task, automatically handling memory allocation. This tutorial explains how to usegetlineeffectively, covering its parameters, return values, and memory management. With practical e...
In the following example, we are going to consider the basic usage of the getline() function.Open Compiler #include <iostream> int main() { char x[20]; std::cout << "Enter a line of text: "; std::cin.getline(x, 20); std::cout << "Entered Input : " << x << std::endl;...

The getline() function is prototyped in the stdio.h header file. Here are the three arguments: &buffer is the address of the first character position where the input string will be stored. It’s not the base address of the buffer, but of the first character in the buffer. This pointer...
