Allocate Struct Memory With malloc in C Delft Stack
Malloc is the core function for dynamic memory allocation in C that takes a single integer argument representing the number of bytes to be allocated To allocate the memory of the custom struct object that has been defined we should call the sizeof operator and retrieve the amount of memory the object needs to be stored

This program asks the user to store the value of noOfRecords and allocates the memory for the noOfRecords structure variables dynamically using the malloc function Demonstrate the Dynamic Memory Allocation for Structure C Program to Store Data in Structures Dynamically. Example Access members using Pointer To access members of a structure using pointers we use the operator In this example the address of person1 is stored in the personPtr pointer using personPtr person1 Now you can access the members of person1 using the personPtr pointer The name malloc stands for memory allocation The malloc function reserves a block of memory of the specified number of bytes And it returns a pointer of void which can be casted into pointers of any form Syntax of malloc ptr castType malloc size Example ptr float malloc 100 sizeof float
