the programme is to find first 100 prime number..
i searched alot in net but its of high level...

Aap lucky ho - I'd this code form my college days... ab mujhey nahin ilm keh aap is mein kahan tak kamyab ho pao gey..

#include <iostream>
#include <deque>
#include <cmath>
#include <fstream>
#include <iterator>
std::deque<unsigned long> read_primes() {
std::deque<unsigned long> P;
std::ifstream primes("Primnumb.txt");
if (primes){
copy(std::istream_iterator<unsigned long>(primes),
std::istream_iterator<unsigned long>(),
back_inserter(P));
P.pop_front();
}
else {
primes.close();
P.push_back(3);
std::ofstream primes("Primnumb.txt",
std::ios::out|
std::ios::app);
primes << "2" << std::endl;
primes << P.back() << std::endl;
}
primes.close();
return P;
}
int main() {
std::deque<unsigned long>P;
unsigned long long i;
double root;
bool is_prime;
std::cout << "Reads primnumber from file... ";
P = read_primes();
std::cout << "\n\nFaerdig!\n" << std::endl;
std::cout << "PrimNumber " << P.size()+1 << " Read from the file!\n" << std::endl;
std::cout << "Press a button to start";
std::cin.get();
std::cout << "\nPlease wait while the file is prited. This can take a while...\n\n" << "Write prim number between " << P.back() << " and 18446744073709551615 to the file... ";
std::ofstream primes("Primtal.txt",std::ios::out|std::ios::app);
for (unsigned long long test = P.back() + 2; test != 100; test += 2) {
root = sqrt(test);
for (i = 0, is_prime = true; P[i] <= root && is_prime == true; i++)
if (test % P[i] == 0) is_prime = false;
if (is_prime == true && test <= 0xffffffff) P.push_back(test);
if (is_prime == true) primes << P.back() << std::endl;
}
primes.close();
std::cout << "Finished!" << std::endl;
std::cout << "Created by Tariq!" << std::endl;
std::cout << P.size()+1 << " Prim number found between 0 and 18446744073709551615";

lolss yaar mujhe tu yeh programe daikh kay 4 saal pahlay ka zamana yaad aa gaya.
Kabhi humari bi C++ kamal ki hoti thi lolss
yaar bhai ap ko ek tip daita hon yh prg. aisi cheez hai ap yeh na sochi yeh high level ka hai es ko ghaur se parho aur samjho aur esko baar baar likho code ko. kisi jagah apnay haath se. aur phir bina daikhay coding karo agar ap chahtay ho kah sab kuch apkay level pe aa jaye tu yh mumkin nahi hai ap ko apnay level prg. mein thora high karna paray ga aur yeh jo oper code hai mera khayal hai sab se easy hai.

agar ap wo C# kay method se karna chahtay ho tu mein apko mashwara don ga wo nahi karna i.e printf(var). yeh easy hai classes mein banaya gaya hai. mein tu apna sara data pakistan hi chorh aya warna meray paas es cheez ko bananay kay 5 tareeqay thay ab wasta hi nahi raha tu meri practice warna apko help kar daita.
phir bhi ap ko kahoon ga kah yeh classes hain esko ghaur se samajho aur phir simple fuction use kar kay apni coding kar lo aur programe bana lo coz agar copy paste karo gai tu programming nahi seekh sako gai kabhi bi. khud se try karo yaraa .
Wish u best of luck. (Y)

lolss yaar kamaal bhi humara ek bhayoon jaisa dost hay ek oski howi humari howi ek hi baat hai lolsss.. ap itni gehraiii mein na jao mein ne C++ programming language ki baat ki hai kisi larki ki nahi :shh: :wk
