Trying to write a function, Even, that will tell you the total amount of even numbers in the array
#include <iostream>
using namespace std;
const int MAX_ROWS = 3;
const int MAX_COLUMNS = 2;
int Even(int A[int length][int width], int length, int width) {

I keep getting an error here and cant quite figure out why,
Code:
else if (mainMenu == 3){
cout << "Please make a selection" << endl
<< " 1) Withdraw from account" << endl
<< " 3) Back to main menu" << endl;
cin >> withdrawMenu;
if (withdrawMenu == 1){
[Code] ....
This is what i have example code in c++:
#include <iostream>
class Foo{
public:
void bar(){
std::cout << "Hello" << std::endl;
[Code] ....
After compiling it is giving error as :
foo.cpp: In function ‘int Foo_max(Foo*)’:
foo.cpp:26:37: error: expected primary-expression before ‘int’
foo.cpp:26:46: error: expected primary-expression before ‘int’
This is my code so far and in my else if statements its sayin "Expected Primary Expression Before "Else"
What do i do?
#include <iostream>
using namespace std;
int main () {
//declare variable
double n,a,b,c,d,total;
[Code] ....
work out this error?

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.
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[] ) );
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.
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;

I'm trying to make a program that allows the user to input an arbitrary amount of numbers and finding the largest of all the inputs but I keep having problems with the output.

And regardless of what numbers I enter, I always get the output of 10. Also I got the EOF idea from my textbook so if there is a better way of doing this I'd like to hear it. I don't know any clear ways that looks nice to end the while loop when the user doesn't have any more numbers to enter.
Write a C++ program to calculate the fewest number of each denomination needed to pay a bill of amount TOTAL. For example, if the end user enters $97 for TOTAL, program will output that the bills would consist of one $50 bill, two $20 bills, one $5 bill, and two $1 bills. (Assume that the amount is in whole dollars, no cents, and only $100, $50, $20, $10, $5, and $1 denominations are available.) Aid: You may want to use the modulus operator %.

My problem is that.When i start with this

I get 0 if i enter a number between 0 and 4(0 and 4 included). I don't know where I am doing a mistake. I also want to know if i can handle this buy just if statements. or how can i do it by while and for loops ?
I am facing a problem which i could not obtain the total numbers which is greater than the average value. For example:
#include <iostream>
using namespace std;
int main (){
int size , count;
double no, max, min ,total, sum , average;
[Code] ....
In this case im able to compute the average of the numbers but when it comes to capture the total of numbers which is greater than the average value, how to compile the code , because the average number is only been compute once all the value capture by the input of user is sum up.
Code: i am trying to display the information in the array as a table and add the total rows and the total colums separately
#include<stdio.h>
int main(void)

int row, col;

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.
I want to implement a function into the code below that sorts the user defined amount of random numbers and then sorts them in ascending order.

using namespace std;

The question was to evaluate postfix expression (floating point numbers). I had been able to implement stack data structure using one way singly linked list linked list but I am not been able to extract the original input by the user expressions like
ex:
1. 252.124 3453.7 * 46.3 346.2 23.6 ^/$
2.45.23 87.045 * 6.5 ^$
etc,($ELIMETER)
How to take such inputs from the user for proper evaluation . Previously I tried to extract separate digits from integer and decimal fields and computed numbers. The method is very lengthy. Any optimised way for taking such input!
I have a text file like below read.txt:
1.0 2.0 3.0 4.0
2.0 3.0 4.0 6
5.0 7 1.0 5.0
calc.cpp:
void main() {
FILE *fp;
fp=fopen("read.txt","r");
double *read_feature = new double*[3];

I want to count all the numbers in my text file (read.txt). Read text file consist of floating and integer number. Answer for the above file would be integer=2 and float =10.

This will read in a list of n values, where n is not known ahead of time. The number of values read into the array will be saved in n.

array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) {
int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0;
for (auto i : array) {
sum += i;

How can i count the total no of unique elements in an array? Like I have an array.
Code:
int array[]= { 2,1,4,0,3,3,0,0,1,2,1,1}
// As it has 0,1,2,3,4 as unique values so total no of unique values are=5
int unique =5;
I need to create a program that will find the total of all the elements in array. I need to use for loop and the array size is 10.The output should be like this: i used user input
Input array 0 : 2
Input array 1 : 4
Input array 2 : 6
Input array 3 : 7
Input array 4 : 8
Input array 5 : 9
Input array 6 : 10
Input array 7 : 12
Input array 8 : 16
Input array 9 : 20
Sum of 10 numbers in an array is = 94..Press any key to continue..I have a code but the output is not like that. Here is the code,

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.
