Malloc In C
The malloc or memory allocation method in C is used to dynamically allocate a single large block of memory with the specified size It returns a pointer of type void which can be cast into a pointer of any form It doesn t Initialize memory at execution time so that it has initialized each block with the default garbage value initially Dynamic Memory Allocation in C using malloc calloc free and . Example ptr float malloc 100 sizeof float The above statement allocates 400 bytes of memory It s because the size of float is 4 bytes And the pointer ptr holds the address of the first byte in the allocated memory The expression results in a NULL pointer if the memory cannot be allocated C calloc Create an Array of struct Using the malloc Function in C There is another way to make an array of struct in C The memory can be allocated using the malloc function for an array of struct This is called dynamic memory allocation
