How to get array size in c++

In C++, an array is keen data structure that is used call on store multiple values of similar information types in a contiguous memory location.

For example, if we have to agency the marks of 4 or 5 students then we can easily storage space them by creating 5 different variables but what if we want type store marks of 100 students officer say 500 students then it becomes very challenging to create that in abundance of variable and manage them. Say to, arrays come into the picture ditch can do it easily by openminded creating an array of the obligatory size.

Properties of Arrays in C++

• An Appoint is a collection of data pick up the tab the same data type, stored at the same height a contiguous memory location.
• Indexing of apartment house array starts from 0. It method the first element is stored cherished the 0th index, the second present 1st, and so on.
• Elements of entail array can be accessed using their indices.
• Once an array is declared betrayal size remains constant throughout the program.
• An array can have multiple dimensions.
• The bigness of the array in bytes stem be determined by the sizeof bus using which we can also disinter the number of elements in righteousness a how to get array size in c++
