Chapter 7: Problem 63

T F C++ allows you to partially initialize an array.

Short Answer

Expert verified

Yes, C++ allows partial array initialization. When an array is partially initialized, the uninitialized elements are assigned default values according to their data type. For instance, an integer array with 10 elements can be partially initialized with only the first five elements, and the remaining elements would be automatically initialized with the default value of 0. Example: ```cpp int myArray[10] = {1, 2, 3, 4, 5}; // Only the first 5 elements are initialized ```

Step by step solution

Understand Array Initialization in C++

First, let's talk about array initialization in C++. Array initialization refers to the process of assigning starting values to the elements of an array. In C++, an array can be fully or partially initialized depending on the developer's requirement.

Array Declaration and Full Initialization

In C++, an array can be declared and fully initialized by specifying the data type, array name, size, and the values to be assigned to the array elements. For example, an integer array with 5 elements can be declared and initialized as follows: ```cpp int myArray[5] = {1, 2, 3, 4, 5}; ```

Partial Array Initialization in C++

Now let's move on to partial array initialization. C++ does allow partial array initialization, which means that an array can be declared with a certain size and initialized with less than the total number of elements. For example, an integer array with 10 elements can be partially initialized as follows: ```cpp int myArray[10] = {1, 2, 3, 4, 5}; // Only the first 5 elements are initialized ``` In this case, the first five elements of the array are initialized with the given values (1, 2, 3, 4, and 5), while the remaining elements are automatically initialized with the default value of the data type, which is 0 for integers.

Conclusion

As demonstrated in Steps 2 and 3, C++ does indeed allow partial array initialization. When an array is partially initialized, uninitialized elements are assigned default values according to their data type.
