How array and pointer are related

WebTo check if all the elements of an array are less than a given number, we need to iterate over all the elements of array and check each element one by one. For that we can use a STL Algorithm std::all_of (), which accepts the start & end iterators of an array as first two arguments. As this 3rd argument it will accept a Lambda function. WebAn array stores the variables of similar data types and the data types of the variables must match the type of array. Conversely, the pointer variable stores the address of a variable, of a type similar to a type of pointer variable type. We can generate an array of pointers i.e. array whose variables are the pointer variables.
