The use of a pointer or reference inside a function is a little slower than using a copy of the data because it has to be dereferenced each time, but this is generally faster than all the work needed to copy a big data structure, especially with a constructor (don't worry; you will learn about them soon).
C# supports pointers in a limited extent. A C# pointer is nothing but a variable that holds the memory address of another type. But in C# pointer can only be declared to hold the memory address of value types and arrays. Unlike reference types, pointer types are not tracked by the default garbage collection mechanism. For the same reason pointers are not allowed to point to a reference type or even to a structure type which contains a reference type.
We can say that pointers can point to only unmanaged types which includes all basic data types, enum types, other pointer types and structs which contain only unmanaged types. The fixed statement is typically implemented by generating tables that describe to the Garbage Collector, which objects are to remain fixed in which regions of executable code.
Thus as long as a Garbage Collector process doesn't actually occur during execution of fixed statements, there is very little cost associated with this. However when a Garbage Collector process does occur, fixed objects may cause fragmentation of the heap.
Hence objects should be fixed only when absolutely necessary and only for the shortest amount of time.
I have to write a program that will find the mode of a group of numbers. How should I tackle it using a pointer to find the number that appears most and producing a number of how many times the mode appears.-This is what the output should look like:Output for ex. 1 data:The data set has 1 mode.The value 2 appeared 3 times in the data set.Output for ex.
2 data:The data set has 2 modes.The value 2 appeared 2 times in the data set.The value 4 appeared 2 times in the data set.Output for ex. 3 data:The data set has no mode.Output for ex. 4 data:The data set has 3 modes.The value 1.7 appeared 3 times in the data set.The value 3.1 appeared 3 times in the data set.The value 5 appeared 3 times in the data set.
