advanced patterns When Modifying Struct Members in an Array of Structs in C
After trying multiple solutions online, I still can't figure this out... I'm working with unexpected behavior when trying to modify members of a struct that is stored in an array. I'm using GCC version 11.1.0 on Linux. I have a struct `Point` defined as follows: ```c typedef struct { int x; int y; } Point; ``` I then declare an array of `Point` structs and initialize it: ```c Point points[3] = {{1, 2}, {3, 4}, {5, 6}}; ``` After initializing the array, I attempt to modify the `x` coordinate of the second element like this: ```c points[1].x = 10; ``` However, when I print the values of the points after the modification, I'm seeing that the change hasn't been applied as expected: ```c for (int i = 0; i < 3; i++) { printf("Point %d: (%d, %d)\n", i, points[i].x, points[i].y); } ``` The output still shows the second point as `(3, 4)` instead of `(10, 4)`. I’ve verified that I'm accessing the correct index and that there are no issues with out-of-bounds access. In fact, I’ve tried printing the address of `points[1]` before and after modification to check if they match, and they do. Here’s the output I get: ``` Point 0: (1, 2) Point 1: (3, 4) Point 2: (5, 6) ``` I also ensured that no other part of my code is inadvertently resetting the value of `points[1].x`. This is driving me nuts because I need to identify where the scenario lies. Am I missing something, or is there a specific case where struct members can behave unexpectedly in this context? Any guidance on what to check would be appreciated! My development environment is Ubuntu.
