Smart Pointers in C++ and How to Use Them

  Smart Pointers in C++ and How to Use Them In this article, we will be discussing smart pointers in C++. What are Smart Pointers, why, and how to use them properly? Pointers are used for accessing the resources which are external to the program – like heap memory. So, for accessing the heap memory (if anything is created inside heap memory), pointers are used. When accessing any external resource we just use a copy of the resource. If we make any change to it, we just change it in the copied version. But, if we use a pointer to the resource, we’ll be able to change the original resource. Play Video Click here for the Complete Course! Problems with Normal Pointers Take a look at the code below. C++ #include <iostream> using namespace std;   class Rectangle { private :      int length;      int breadth; };   void fun() {      // By taking a pointer p and      // dynamically creating object      // of class rectangle      Rectangle* p = new Rectangle(); }   int main() {

Operator Overloading in C++

Operator Overloading in C++ In C++, we can make operators to work for user defined classes. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +. Other example classes where arithmetic operators may be overloaded are Complex Number, Fractional Number, Big Integer, etc. A simple and complete example #include<iostream> using namespace std;   class Complex { private :      int real, imag; public :      Complex( int r = 0, int i =0)  {real = r;   imag = i;}             // This is automatically called when '+' is used with      // between two Complex objects      Complex operator + (Complex const &obj) {           Complex res;           res.real = real + obj.real;           res.imag = imag + obj.imag;           return res;      }      void print() { cout << real << " + i" << imag << endl; } };   int main()

How would you read in a string of unknown length without risking buffer overflow

How would you read in a string of unknown length without risking buffer overflow #include <stdio.h> #include <stdlib.h> char * inputString ( FILE * fp , size_t size ){ //The size is extended by the input with the value of the provisional char * str ; int ch ; size_t len = 0 ; str = realloc ( NULL , sizeof ( char )* size ); //size is start size if (! str ) return str ; while ( EOF !=( ch = fgetc ( fp )) && ch != '\n' ){ str [ len ++]= ch ; if ( len == size ){ str = realloc ( str , sizeof ( char )*( size += 16 )); if (! str ) return str ; } } str [ len ++]= '\0' ; return realloc ( str , sizeof ( char )* len ); } int main ( void ){ char * m ; printf ( "input string : " ); m = inputString ( stdin , 10 ); printf ( "%s\n" , m ); free ( m ); return 0 ; }
