C :: Stack Overflow - Expected Expression Error
Sep 10, 2013
I'm pretty new to C, and keep getting an error. Basically I'm trying to convert a ppm image to all red. Here is my code that I can't get to work:
Code:
change(pixel_t *PIXEL, &w, &h,pixel_t *buffer);
And here is the beginning of my convert function:
Code:
void change(pixel_t *pixel, int w, int h, pixel_t *buffer) {
int average, sum;
int i;
pixel_t *pointer;
Everything else works fine. I keep getting an error when I call the convert function. It says "expected expression before pixel_t" and "too few arguments to function "change". I know that everything else in the main is working.

After not programming for sometimes I decided to program a small application. But I have some trouble according to what I remember and re-checking arrays online. I don't understand how the code I wrote below is possible, shouldn't give a stack overflow error or something to that extent? Instead it gives me the value of 3.
#include "stdafx.h"
#include<iostream>
int _tmain(int argc, _TCHAR* argv[]) {
int arr2 [2];
arr2 [3] = 3;
[Code] ....

I am trying to implement the insert function of a binary tree. Atm when I try and insert 3 nodes, the program breaks and gives me a stack overflow error. The error points to a getter function for an identifier for the data in my node class.
void LinkedList::add(Product *myProduct) {
if (_length==0) {
_head = new Node(NULL, NULL, myProduct);
_end = _head;
_length=1;
[Code] ....
Here is my insert function, the error message is
"An unhandled exception of type 'System.NullReferenceException' occurred in SDI2.exe
Additional information: Object reference not set to an instance of an object. "
In my main I have declared an instance of product, "productToAdd = new Product(id,idPrice);" so I'm a bit confused as to what I need to include..

I'm getting a stack overflow error because for large numbers, this code I'm working on allocates too much on the stack.
Is there a way of tracking stack allocations specifically?
Will multithreading solve my problem if each thread is doing the static allocations?
Would I really have to use malloc or new every time I wanted to use memory just to make my code scale to huge numbers?

I usually check if a bit is set using:
Code: bit = (number >> n) & 1; where `n` is the bit I want to check...
But I came across a stackoverflow answer saying:
bit = number & (1 << x); will not put the value of bit x into bit unless bit has type _Bool (<stdbool.h>).
Otherwise, bit = !!(number & (1 << x)); will..
So why is this? why the double !?

I wrote a program, that generates 20 random integers, and stores them in an array. Then I decided, to build more functions to it, i.e why not have it to display the lowest integer of an array. I created my function,
Code:
int minValue( int field[ ] )
and got my code in side, which (technically) works. In my main() function I'm calling
Code:
printf( "The smallest value of an array is: %d
", minValue( field[] ) );
and I'm getting an error trying to compile it.
Code:
randomArray.c:62:74: error: expected expression before ']' token
printf( "The smallest value of an array is: %d
", minValue( field[] ) );

It's been awhile since I've coded in C. I'm picking it back up to get some practice. I'm going through my old programs from a few years ago, and I ran into one where I'm calculating the entropy of a file. The problem I'm having is that everytime the program runs, no matter what file I choose for it to calculate the entropy on, it gives 3.00000 as a result. I've gone through it and can't seem to figure out why it's possible doing that.
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
#define SIZE 256
int entropy_calc(long byte_count[], int length) {
float entropy;
float count;

Write a program that evaluates postfix expression using array implementation of stack.
The expression [the input] is evaluated from left to right using a stack. When the element read from the expression is an operand, push it into the stack.When the element read from the expression is an operator: Pop two operands from the stack.Evaluate the two operandsPush the result of the evaluation into the stack.
The final result lies on the top of the stack at the end of the calculation. Make sure to display the result before terminating the program.Write a program that evaluates postfix expression using array implementation of stack.

#include <stdio.h>
#include <string.h>

I have a program that rolls two dice however many times the user specifies and counts the occurrences of each total (2-12). I have to compare the results of the random rolls to the expected outcome and give the percentage of error between the two.
I have an example that tells me the sum to expected outcome are as follows if I roll 36 times: 2/1, 3/2, 4/3, 5/4, 6/5, 7/6, 8/5, 9/4, 10/3, 11/2, 12/1 but I don't know how to put that into code to get the expected outcome for X amount of rolls.

My compiler (GCC) keeps expecting an expression where it shouldn't in 1 specific piece of my code:
int zxcNewWindow( HWND parent, TCHAR *text, zxWINDOW *kid,
UINT style, int x, int y, int w, int h, int type )
// right here
{
*kid = zxDefWINDOW;
The project contains only 2 files right now and the settings are just the default for an empty Code::Blocks 12.11 project. Both files are in UTF-8 format (tried in ASCII too), I just cannot see why this is not compiling correctly. I'll post the files in the next two posts.
Edit: For those of you who didn't get what the error was from the above here's the full log:
mingw32-gcc.exe -Wall -g -DzxDEBUG -c C:MePrjscppzxGUImain.c -o objmain.o
C:MePrjscppzxGUImain.c: In function 'zxcNewWindow':
