Question

Assume that array 1 and array 2 are both 25 -element integer arrays. Indicate whether each of the following statements is legal or illegal. A) arrayl = array2: B) cout \(\langle\langle\text { array } 1:\) C) \(\operatorname{cin} \gg\) array 2

Short answer

Question: Determine if the following statements are legal or illegal when working with 25-element integer arrays: A) array1 = array2 B) cout << array1 C) cin >> array2 Answer: A) Illegal: Arrays in C++ do not support direct assignment operations. To assign values from one array to another, we must use a loop. B) Illegal: To print the elements of an array, a loop is required. The given statement only prints the memory address of the first element. C) Illegal: Similar to printing, a loop is needed to input values for each array element. The given statement only takes input for the first element, leaving the rest uninitialized.

Step-by-step solution

A) array1 = array2

This statement is illegal. In C++, arrays do not support assignment operations like '=' directly. To assign the values of one array to another, we need to loop through the arrays and assign each value individually.

B) cout

This statement is illegal. To print the elements of an array, we need to use a loop to iterate through each element and print it. Using 'cout << array1' will only print the memory address of the first element, not the actual values stored in the array.

C) cin >> array2

This statement is also illegal. Similar to printing the elements of an array, we need to use a loop to input values for each element of the array. Using 'cin >> array2' will only take input for the first element, leaving the rest uninitialized.
