Issue with Struct Initialization in C Leading to Unexpected Output
I need help solving I'm stuck on something that should probably be simple. I'm working on a project and hit a roadblock... I'm encountering an issue with initializing a struct in C, and it's causing unexpected behavior in my program. I have defined a struct to hold some configuration parameters for my application, but when I try to initialize it, the values seem to be getting mixed up. Here's the relevant code: ```c #include <stdio.h> #include <string.h> typedef struct { int id; char name[50]; float threshold; } Config; void initializeConfig(Config *cfg) { cfg->id = 1; strcpy(cfg->name, "Default"); cfg->threshold = 0.75; } int main() { Config appConfig; initializeConfig(&appConfig); printf("ID: %d, Name: %s, Threshold: %.2f\n", appConfig.id, appConfig.name, appConfig.threshold); return 0; } ``` When running this code, I expect to see: ``` ID: 1, Name: Default, Threshold: 0.75 ``` However, I occasionally see garbage values instead of the expected output. I suspect that this might be due to how the struct is being initialized or possibly some memory corruption elsewhere in the program. I’ve ensured that the rest of the code is not modifying the `appConfig` variable after initialization, but I still see this behavior intermittently. I also tried using `memset()` to clear the struct before initialization, but that didn't seem to help. Here’s how I attempted it: ```c memset(&appConfig, 0, sizeof(Config)); initializeConfig(&appConfig); ``` This approach produced similar issues. I'm using GCC version 11.2 on Linux. What could be causing this behavior, and how can I properly ensure that my struct is initialized without encountering these random garbage values? My development environment is Windows. My development environment is macOS. I'm developing on Ubuntu 20.04 with C. How would you solve this?
