Asking Questions

Why This Matters: Get Help Faster

  • Good questions get answered in minutes

  • Poor questions get ignored or require endless back-and-forth

  • Time is limited - make yours count

  • Clear questions help others with the same problem

Before Asking: The 5-Minute Rule

Do This First (Saves Everyone Time)

  • Try debugging yourself: Add printf statements, check for typos

  • Read error messages carefully: They often tell you exactly what's wrong

  • Check documentation: Man pages, references, available materials

  • Search forums: Your question might already be answered

  • Attempt the problem: Show specific issues, not entire tasks

Red Flags That Get Questions Ignored

  • "My code doesn't work" (too vague)

  • Screenshot of code (can't copy/paste to test)

  • "I haven't tried anything yet"

  • No error message included

  • Asking for complete solutions without showing effort

Question Structure: What's Needed for Fast Answers

Start With Context (One sentence each)

  • What you're working on: "Implementing a linked list insertion function"

  • Environment: "GCC 9.4 on Ubuntu 20.04"

  • Goal: "Trying to insert nodes in sorted order"

Describe the Problem Clearly

  • What you expected: "Should insert 5 between 3 and 7"

  • What actually happens: "Segmentation fault on line 23"

  • Include exact error message: Copy/paste the full error as text or link to a pastebin site: pastebin, mystbin, laravel

Show Your Code (The Right Way)

  • Copy and paste as text - never screenshots

  • Include only relevant parts - not your entire 500-line program

  • Make it runnable - include necessary headers and sample data

  • Point to the problem line: "Error happens in the while loop"

The Magic Formula: Minimal Example

What Gets Fast Responses

#include <stdio.h>
#include <stdlib.h>

typedef struct Node {
    int data;
    struct Node* next;
} Node;

void insert_sorted(Node** head, int value) {
    Node* new_node = malloc(sizeof(Node));
    new_node->data = value;
    
    // Problem happens here - segfault when list is empty
    if (*head == NULL || (*head)->data > value) {
        new_node->next = *head;
        *head = new_node;
    }
    // ... rest of function
}

// Expected: Insert 5 into empty list
// Actual: Segmentation fault

Why This Works

  • Code can be copied and compiled immediately

  • Problem is isolated to specific function

  • Shows understanding of the goal

  • Takes 30 seconds to spot issue

Common Question Types: Templates

Compilation Error Template

**Context**: Working on [specific feature/function]
**Compiler**: GCC 9.4
**Error**: [exact compiler message]
**Code**:
[minimal example that won't compile]
**What I tried**: [briefly list attempts]

Runtime Error Template

**Goal**: [what the code should accomplish]
**Problem**: [specific error - segfault, wrong output, etc.]
**Code**:
[minimal example that reproduces the issue]
**Expected output**: [what should happen]
**Actual output**: [what actually happens]

Logic/Algorithm Help Template

**Task**: [specific algorithm or function]
**Current approach**: [your strategy]
**Stuck on**: [specific step you can't figure out]
**Attempted**: [what you've tried so far]

What NOT to Ask

Questions That Get Ignored

  • "Can you check my entire program?"

  • "Is this right?" (without specific concern)

  • "How do I implement X?" (no attempt shown)

  • "My code has bugs somewhere"

  • "Can you debug this for me?"

Ask This Instead

  • "Line 23 gives segfault - why?"

  • "Does my pointer logic look correct?"

  • "Tried malloc but getting wrong values"

  • "Found issue on line 15, but don't understand why"

  • "Can you explain why this specific line fails?"

C-Specific Best Practices

Include Compilation Command

# How I'm compiling:
gcc -Wall -Wextra -g -o program program.c

# Error message:
program.c:15:12: warning: assignment from incompatible pointer type

Show Debugging Attempts

printf("Before malloc: ptr = %p\n", ptr);
ptr = malloc(sizeof(int) * 10);
printf("After malloc: ptr = %p\n", ptr);  // Shows debugging effort

Memory Issues - Provide Minimal Case

// Simplified version that shows the memory leak
int* create_array() {
    int* arr = malloc(sizeof(int) * 5);
    // Should I free here? Getting confused about ownership
    return arr;
}

Pointer Confusion - Show Your Understanding

// I think this should work but getting garbage values
int x = 10;
int* ptr = &x;
printf("Value: %d\n", *ptr);  // Expected: 10, Actual: garbage
