c++ malloc header, In C++, the malloc() function is used for dynamic memory allocation and is defined in the <cstdlib> header. It allocates memory but does not initialize it, returning a void* pointer that must be typecast.
ostream> #include <cstdlib> // Required for malloc() int main() { int* ptr = (int*)malloc(sizeof(int)); // Allocate memory for an integer if (ptr) { *ptr = 42; std::cout << "Value: " << *ptr << std::endl; free(ptr); // Free allocated memory } return 0; }
C++ prefers new over malloc() since new calls constructors, making it safer.
