Memory usage is really important in C and C++ programming. In the C language malloc, calloc, realloc functions comes from the <alloc.h> header and C++ language allows you to use malloc in C++ also calloc and realloc too. These memory allocations are fairly old and mostly used in C and require great caution if you use them in C++. In modern C++ we should use modern ways of C++ like std::vector…
Pointers are variables that hold addresses and the asterisk character ‘*’ is used to define pointers, it is used before the variable name. This variable can be an integer, float, string, or any data block like structs, object arrays, bitmaps coming from a…
In all programs, not just in C programming, all data and operations during runtime are stored in the memory of our computers, including IoT or other microdevices. This memory is generally a RAM (Random Access Memory) that allows data items to be read or written in almost the…
In computers, all data and operations during runtime are stored in the memory of our computers, IoTs, or in other microdevices. This memory is generally RAM (Random Access Memory). RAM allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.
In this post, you’ll learn how to use memory in C and C++, how to…
