Question

Given: An array named testScores has already been declared. - size = 5 data type = float. - The array has already been initialized with these values: 77, 88.5, 90, 93, 71.5 Write one statement to declare a pointer named: ptr - In the same statement, assign the address of the testScores array to the pointer.

Answer 1

In the question given, we made use of c++ coding language for implementation.

Step-by-step explanation:

From this question given,

we make use of C++ code language

Now, executed the steps in c++ in the question. comments were also included for each line in code for better understanding.

C++ Code:

#include <iostream>

using namespace std;

//main function

int main()

{

//initialize the float array

float testScores[5] = {77, 88.5, 90, 93, 71.5};

//assign a pointer to the array

float *ptr = testScores;

//output memory address of first element in array

cout<<"Memory address of first element using & operator: "<<&testScores[0]<<endl;

cout<<"Memory address of first element using pointer: "<<ptr<<endl;

//display array elements using pointer in for loop

cout<<"Array elements using pointer: \\";

for(int i=0;i<5;i++)

{

//dereference pointer using *ptr and

//add i for subsequent elements in array

cout<<*(ptr+i)<<endl;

}

return 0;

}
