Chapter 7: Problem 87

Definitions and program segments has errors. Locate as many as you can. int array1[4], array2[4] = {3, 6, 9, 12}; array1 = array2;

Short Answer

Expert verified

Answer: The error in the given code was attempting to directly assign the contents of "array2" to "array1" using `array1 = array2;`. This is not valid in C as arrays cannot be assigned directly. To fix this error, we need to use a loop to copy the elements of "array2" to "array1" individually, like this: ```c for (int i = 0; i < 4; i++) { array1[i] = array2[i]; } ```

Step by step solution

Analyze the array declarations and initializations

Here is the original code: ``` int array1[4], array2[4] = {3, 6, 9, 12}; ``` This code declares and initializes two integer arrays, named "array1" and "array2". Both arrays can hold 4 integers. The first array, "array1", is uninitialized, whereas the second array, "array2", is initialized with the values 3, 6, 9, and 12. There are no errors in this line.

Analyze the array assignment

Next, let's analyze the following line: ``` array1 = array2; ``` This line attempts to assign the contents of "array2" to "array1". However, this is not valid in C, because arrays cannot be assigned directly. This is a syntax error.

Provide a correct solution

To fix the error found in Step 2, we should use a loop to copy the elements of "array2" to "array1" individually. Here's a corrected version of the code: ``` int array1[4], array2[4] = {3, 6, 9, 12}; for (int i = 0; i < 4; i++) { array1[i] = array2[i]; } ``` This code first initializes both arrays, as before. Then, it uses a "for" loop to iterate over the indices of the arrays (from 0 to 3). Inside the loop, the program copies each element of "array2" to the corresponding element of "array1". In conclusion, the given code had one error, and the corrected code now properly copies the elements of "array2" to "array1" using a "for" loop.
