Segmentation Fault When Accessing Struct Member After Dynamic Allocation in C
I'm wondering if anyone has experience with I've been struggling with this for a few days now and could really use some help. I'm working with a segmentation fault when trying to access a member of a struct after dynamically allocating memory for it. The struct is defined as follows: ```c typedef struct { int id; char name[50]; } Person; ``` In my main function, I have the following code: ```c #include <stdio.h> #include <stdlib.h> int main() { Person *p = (Person *)malloc(sizeof(Person)); if (p == NULL) { fprintf(stderr, "Memory allocation failed\n"); return 1; } p->id = 123; snprintf(p->name, sizeof(p->name), "John Doe"); printf("ID: %d, Name: %s\n", p->id, p->name); free(p); return 0; } ``` When I run this code, I get a segmentation fault, but it seems to work fine for other struct members when I modify the code to use a different data type or access them in a different manner. I've verified that the `malloc` call is successful and that I'm not exceeding the bounds of the `name` array. Is there something fundamental that I'm missing here? I'm using GCC version 10.2.0 on Ubuntu 20.04. I've tried compiling with `-g` for debugging information, but it doesn't point to a specific line in my code. Any insights would be appreciated! I'm working on a API that needs to handle this. Any ideas what could be causing this? I'm working on a CLI tool that needs to handle this. I'd really appreciate any guidance on this. I'm open to any suggestions.
