can any one help to find a specific string between html tags
which is changed to a sting..
weather.html looks (for location) is
<location>somewhere</location>
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
string find_field(string myPage,string);
int main (void) {
string page, line, location, temperature;
ifstream inputFile("weather.xml");
while(getline(inputFile, line)) {
page.append(line);
line.erase();
}
// Now page is a string that contains the whole xml page
// Here you need to write something that finds and
// extracts location and temperature from the XML
// data in the string page and stores them in
// the strings location and temperature respectively
location=find_field(page,"location");
temperature=find_field(page,"temp_c");
cout << "Location: "<<location << endl;
cout << "Temperature: " << temperature << endl;
system("pause");
}
string find_field(string myPage,string find_string){
int temp=myPage.find(find_string);
if(temp!=string::npos) {
cout << "Match found at " << temp << endl;
}
return "found?";
}

Inline parameters : What does the compiler do with the
parameters of inline function, that can be evaluated in
runtime ?

write a program to convert a decimal number in to its equivalent binary number?
209
class CTest
{
public:
void someMethod()
{
int nCount = 0;
cout << "This is some method --> " << nCount;
}
};
int main()
{
CTest *pctest;
pctest->someMethod();
return 0;
}
It will executes the someMethod() and displays the value
too. how is it possible with our creating memory for the
class . i think iam not creating object for the class.
Thanks in Advance...

Is there any error below, its a code to delete all entires
from a map
#include <map>
#include iostream.h
int main()
{
int i =0;
map <int, char> TestMap;
while(i<3)
{
TesMap.insert(TestMap::value_type(i,Test));
i++;
}
typedef map<int, char> :: iterator mapIter =TestMap.begin();
if(mapIter!=TestMap.end())
{
TestMap.erase(mapItrer);
++mapIter;

If P is the population on the first day of the year, B is
the birth rate, and D is the death rate, the estimated
population at the end of the year is given by the formula:
The population growth rate is given by the formula:
B – D
Write a program that prompts the user to enter the starting
population, birth and death rates, and n, the number of
years. The program should then calculate and print the
estimated population after n years. Your program must have
at least the following functions:
1. growthRate: This function takes its parameters the
birth and death rates, and it returns the population growth
rate.
2. estimatedPopulation: This function takes its
parameters the current population, population growth rate,
and n, the number of years. It returns the estimated
population after n years
Your program should not accept a negative birth rate,
negative death rate, or a population less than 2.
please answer my question ....
They started with the brief introduction followed by few
basic C++ questions on polumorphism, inheritance and then
virtual functions.
What is polymorphims?
How you will access polymorphic functions in C?
How virtual function mechanism works?
