Web11 apr. 2024 · It is a faster way of memory allocation. It is a slower way of memory allocation. Once static memory is allocated, neither its size can be changed, nor it can be re-used. Hence, less efficient. We can change the memory size after allocation and can be reused as well. Hence, more efficient. Web1 sep. 2024 · Syntax to use new operator: To allocate memory of any data type, the syntax is: pointer-variable = new data-type; Here, pointer-variable is the pointer of type data-type.
