C :: Expected Expression Before Token

Jun 18, 2014

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[] ) );

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.

C/C++ :: Calculating Entropy Of A File - Expected Expression And Too Few Arguments

Sep 22, 2014

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;

C++ :: Name Resolution Not Working As Expected

Apr 23, 2013

I have a global var (m) with an initial value 5.

I have a template class (A) that derives from a either a base class that has a member (_A1.m) or not (_A0), based upon it's template parameter. class (A) has a member function (fn) returns the value of (m) as it understands what (m) is.

However, this gives different results compared with a non-template class in a similar scenario. I'm expecting that if derived from _A1, that m should be taken from the base class scope and if derived from _A0, it should be taken from the global one.

Here is the code for your amusement:

int m = 5;
class _A0 {
public:
_A0(int) {

[Code] ....

This compiled using g++ 4.5.3 and 4.6.3 with the same results:
Global value of m is: 5
B0 class has no internal m member. Object resolves m internally with value 5
B1 class has internal m member. Object resolves m internally with value 3
A<_A0> class has no internal m member. Object resolves m internally with value 5
A<_A1> class has internal m member. Object resolves m internally with value 5

C++ :: Destructors Being Called More Than Expected?

May 20, 2013

In this code:

#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}

[Code] .....

Before the program ends, at return 0;

I would expect the CBox destructor to be called 3 times but it is being called 6 times? Why? Also in this code:

#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}

[Code] .....

Why is the destructor called 3 times? When have you really destroyed a CBox? Doesnt emplace only create it and store it, then thats it?

[URL] .....

For pushback:

void push_back(value_type&& _Val)
{// insert by moving into element at end
if (_Inside(_STD addressof(_Val)))
{// push back an element
size_type _Idx = _STD addressof(_Val) - this->_Myfirst;

C :: Float Variable Increases More Than Expected

Sep 14, 2014

I just wrote the following simple program:

Code:
#include <stdio.h>
#include <math.h>
int main(void) {
float fx, x;

[Code] ....

The output increases x by 0.1 as expected until x=1.5. After that x becomes 1.600001 and not 1.6 as expected.

C :: GSL And OpenMP - Getting Random Numbers That Are Out Of Expected Range

May 2, 2013

I am trying to parallelize some of my code with OpenMP. When I switch to using multiple threads I start getting random numbers that are out of the expected range.

Here is a small example:

Code:
#include <stdio.h>
#include </usr/local/include/gsl/gsl_rng.h>
#include </usr/local/include/gsl/gsl_randist.h>
int main() {
int mySeed=0;
const gsl_rng_type *T;
T = gsl_rng_ranlxs2;
gsl_rng *r_1 ;

[Code] .....

gsl_rng_uniform should only output number in the range [0,1) but with multiple threads it outputs larger number as well.

C++ :: Iterative Loop Repeats More Times Than Expected

Nov 28, 2014

I tried my best but I can't figure out the problem. At the last part of "createArray", I output the final array created. I mean it to repeat once but then it repeat more times than I expect. createArray is an iterative function. If it repeats 3 times, than at last the array created which fulfil the criterion would be printed out 3+1 times.

I am trying to create an array with 3 numbers 5 times, resulting in a 2D array. The 3 numbers in a array are picked from 0 - 5. I enter createArray(5,3,5). Then these 5 arrays are compared with each other to see if there are repetitions. If there are, the whole process begins again, 5 arrays with 3 numbers each will be picked again and compared with each other. If there are no repetitions at last, there 5 arrays would be printed out.

void deleteArray(int** array){
delete[] array;
}
int** createArray(int simu_times, int randomrun,int numberofrun){
vector<Int_t>fChosenRun;
int** Array = new int*[simu_times];

C/C++ :: Expected Outcome Error On X Amount Of Rolls

Feb 20, 2015

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.

Visual C++ :: OnSize Handler Not Working As Expected

Nov 6, 2013

I keep having problems with CMFCPropertySheets. I now have it embedded in a resizable dialog and the property sheet and page gets resized when dialog is resized all that is working fine.

Problem is OnSize is being called when the dialog is being resized NOT when it has finished resizing so the values reported in cx and cy is the old size not the size AFTER resizing. What could be causing this? Isn't OnSize call AFTER the size has been changed and OnSizing called WHILE the size is being changed?

I have a list control that needs to take up full rect in each page and when the dialog is maximized it stays at previous size even though the sheet and page have both maximized as they should.

I ran a trace on the OnSize even for both the sheet and page and OnSize is being called during the sizing and not after it has already been sized like it is supposed to.
