An Array Is Used To Store A Collection Of Data, But It Is Often More Useful To Think Of An Array As A Collection Of Variables Of The Same Type.
Printf(“memory allocated to array is %d “ , sizeof(arr) ); By that one can easily get the number of items using the sizeof operator. For the sake of this example, we define a c_array variable and initialize.
