I keep getting a "Declaration syntax error" at line ""int main()". Is there something wrong with my int main()? And how do I go about it? Here is the program:
#include<stdlib.h>
#include<iostream.h>

#include<math.h>
#include<conio.h>
float rung4(float x, float y, float h)

I'm trying to make a function to show the content of maps as follows:
template<typename A, typename B>
void show_map(const std::map<A,B> &src) {
for( std::map<A,B>::iterator it=src.begin(); it!=src.end(); ++it ) {
cout << it->first << " ____ " << it->second << endl;
}
};
However, I got this error in the 'for' line: "error: expected ‘;’ before ‘it’" (and then errors that it is not declared, etc). I'm sure that there is no missing ; in other functions. If you try to write a random line before that you get no error there for example, always in the for.
It is there something that you need to do with iterators when you declare generic datatypes?
void main() {
clrscr();
cout<<" Menu";
cout<<"
1. Display all the employees' info.";
cout<<"
2. Display specific employes' info.";
cout<<"
3. Display employee with max salary.";

Declaration syntax error at line 89, I don't get this everything is proper.
Okay so I'm writing a simple program - so far with just 1 header and 1 .cpp file to go with it. I'm getting strange errors saying that my struct hasn't been recognised even though I declare it in the header. The code involved is --
Code:
#include<stdio.h>
#include<iostream>
#include<sstream>
#include"bots.h"
//#include"prisonersDilemna.h"
//write program to battle multiple bots with a random choice generator
//and after all iterations post who comes out on top.
[Code] ....
||=== Build finished: 6 errors, 0 warnings ===|
How should the syntax be? Why does my program not recognise bot as an object type? Why can I not have a void method?
I am using OpenCASCADE environment to read STL file! I face a problem, with forward declaration error with the following

The above program is not terminated.how to terminate it?
how would I write a function that copies a null-terminated string from one char* buffer to another, without using strcpy? I am trying to avoid strcpy because of the null terminator.
Here is my attempt;
#include <algorithm>
#include <iostream>
static const size_t, data_size =32;
struct tString
{
char data[data_size];
};
std::string buffer = strArray1[0] + strArray2[0];
std::copy(buffer.begin(), buffer.end(), tString[0].data);

I want to count the number of bytes in a stream that contains nulls. I know I can't use strlen() for this, so is there an alternative?
Code:
char *bytes = "x11x12x13x00x12x13x14x15";
I want to be able to say there's 8 bytes here, not 3 as strlen gives me.
I am currently developing a sync module using asp.net. I am getting data from an external database (mysql database) The problem is I am getting the error "Connection unexpectedly terminated" when filling the dataset.
Here's my code
string P_contact = "SELECT A.id, B.firstname, B.middlename, B.lastname FROM Accounts A, Contacts B WHERE A.id = B.id";
MySqlDataAdapter db_P_contact = new MySqlDataAdapter(P_contact, conn);
DataSet ds3 = new DataSet();

As you can see, it has stored the last struct in all three indexes of the array. Why?
i having a code to pass in array as argument, but the length returned is 1. This is not match with the array size.

int len = sizeof(Array)/sizeof(int);
cout << len << "

}
int main()
{
int X[] = {45, 12, 54, 83, 41, 36};
getsize(X);

Currently I am trying to convert RGB to HSL. Everything is working but the saturation value. It is always close to the correct value (usually less than 10 off). For example:
RGB:(196,72,84)
HSL:(354,-46,52)
Correct HSL(354,51,53)
CODE:
double s=0;
double l=0;
chroma=max-min; //works correctly
//LIGHTNESS
l=(max+min)/2;
//SATURATION
if(chroma==0) {s=0;}
else {s=chroma/(1-fabs(2*l-1));}
s=s*100.000000;
l=(l/255.000000)*100.000000;
I am writing a program where I read in data from a file into an array and a 2D array. However, when I cout that data to insure that it was all read in correctly, I get only the first full line of that input file(where there are actually 25 rows and 12 columns).
What am I doing wrong or should be doing differently?
ifstream fin;
//open the input file
fin.open("store_data.txt");
//If input file was opened, read input file data into array and 2d array
if(fin){

I'm writing a program to read in a Master.txt file and then update it through a Transaction.txt file that contains various transaction types [Adds (A), Deletes (D), and Edits (E1-E4)]. The records in both files are in ascending order based on Item#. Ultimately, the original Master.txt and updated Master file (Master2.txt) will be merged to reflect all valid transactions, and an errorLog.txt file will be created to indicate all invalid transactions. I feel I have all of the code written correctly, but I am still getting errors on my operands and identifiers.

Were are to implement a method countValue() that counts the number of times an item occurs in a linked list. Remember to use the STL <list>
int countValue(list<int> front ,const int item);
Generate 20 random numbers in the range of 0 to 4, and insert each number in the linked list. Output the list by using a method which you would call writeLinkedList which you would add to the ListP.cpp.
In a loop, call the method countValue() , and display the number of occurrences of each value from 0 to 4 in the list.
Remember that all the above is to be included in the file ListP.ccp
The output should be:
2 3 4 0 1 0 2 4 2 3 3 4 3 3 3 0 0 2 0 2
0 : 5, 1 : 1, 2 : 5, 3 : 6, 4 : 3
but I am getting:
1 2 4 0 4 4 3 3 2 4 0 0 1 2 1 1 0 2 2 1
0 : 4, 1 : 5, 2 : 5, 3 : 2, 4 : 4,

I'm doing a bitwise operations on 2 bytes in a buffer, then storing the result in a variable. However, I sometimes get a non-zero value for the variable even though I'm expecting a zero value.
The relevant portion of the code is as follows.
unsigned int result = 0;
long j = 0, length;
unsigned char *data;
data = (unsigned char *)malloc(sizeof(unsigned char)*800000);
[Code] ......
I'm expecting result to be zero when my data[j] and data[j+1] are 0xb6 and 0xab respectively, which is the case for most of the time. However, for certain values of j, my result is strangely not zero.
j = 62910, result = 64
j = 78670, result = 64
j = 100594, result = 64
j = 165658, result = 512
j = 247990, result = 128
j = 268330, result = 512
j = 326754, result = 1
j = 415874, result = 256
j = 456654, result = 1024
j = 477366, result = 512
It appears that these strange result values are all powers of 2, with a 1 bit appearing somewhere in the unsigned int.
I'm not changing the value of result anywhere else in the code, and when I print out (unsigned int)(((data[j]^0xb6)<<8)|(data[j+1]^0xab)), I get 0, but somehow when it gets stored in result, it's no longer zero.
