In this tutorial, you will learn what is a memory leak and what is the causes of memory leaks in C/C++ programming. You will also leak to how to avoid memory leaks in C/C++ with programming examples. What is Memory Leak? A memory leak is a curse for software because software shows undefined behavior due […]

What are wild pointers in C? Uninitialized pointers are known as wild pointers. The behavior of uninitialized pointers is undefined because they point to some arbitrary memory location. Wild pointers may cause a program to crash or behave badly. Note: Generally, compilers warn about the wild pointer. int *ptr; //ptr is wild pointer Let see

The basic difference between malloc and calloc function is that calloc() takes two arguments and the space is initialized to all bits zero while malloc takes only one argument and the space value is indeterminate. Both malloc and calloc are memory management functions which use to allocate the memory dynamically. In C language, calloc() gives

The mini-project “Student Record System Project in C” is a console application using the C programming language. This project compiled in Code Blocks with the GCC compiler. In this console application, you can do basic Student Record tasks like adding the student info, view the added student, search the students, ..etc. This application based on

We use the const reference in C++ when we want to refer to a const type. It prevents changing the bounded object and also refers to a constant value (like 6, 27, 2.4 ..etc). In my previous article, I have explained the reference in detail if you had not read it, please check this link,

C++ provides the pointer and reference to refer the object indirectly. But it is our choice to use the pointer or reference in our code for accessing the object indirectly. But C++ insist to use the reference but it is up to you and your requirement. Basically, reference defines an alternative name for an object
