Final answer:
It is true that an embedded loop is typically needed to initialize values in a 2D array, with one loop iterating over the rows and another over the columns.
Step-by-step explanation:
The statement is true. An embedded (nested) for loop is often required to declare or initialize the values in a 2D array. Having two dimensions in an array means there are two levels of indexing, which requires two loops - one nested within the other - to reach every element. Imagine you have a 2D array that represents a grid or matrix, to initialize each cell you would use one loop to iterate over the rows and another inside to iterate over the columns.
Here is a simple example in pseudo code:
for each row in array
for each column in row
set array[row][column] to some value
This code will effectively declare the values for each element in the 2D array. It's important to mention that there are some programming languages and specific scenarios where alternate methods of declaring a 2D array might be applicable, such as initialization at the time of declaration or using array-specific functions.
