malloc allocates memory from code example
Example 1: allocate memory c
ptr = (castType*) malloc(size);
int *exampl = (int*) malloc(sizeof(int));
ptr = (castType*) calloc(n, size);
char *exampl = (char*) calloc(20, sizeof(char));
Example 2: what is the use of malloc in c
In C, the library function malloc is used to allocate a block of memory on the heap. The program accesses this block of memory via a pointer that malloc returns. When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.
