malloc

  1. Include the necessary header file for the malloc function: #include
  2. Declare a pointer variable to store the memory address returned by malloc: int *ptr;
  3. Use malloc to allocate a block of memory for the pointer variable: ptr = (int)malloc(10 sizeof(int));
  4. Check if the memory allocation was successful: if (ptr == NULL) { printf("Memory allocation failed"); exit(1); }
  5. Use the allocated memory for the intended purpose.
  6. Free the allocated memory when it is no longer needed: free(ptr);
