// This is a genius macro from EthanB on StackOverflow
// It's meant to work around Obj-C's missing string concatenation operator

#define stringConcat(...) \

// so now instead of this...
NSString *str = @"things are ";
NSString *str2 = [str stringByAppendingString:@"cool."];

// compile with:
//     g++ -O3 calcpi.cpp -o calcpi.o -std=c++11
// run with:
//     ./calcpi.o <threads> <iterations> <decimal places>
// it's recommended to use multiple threads if possible, but to always specify iterations, as if you don't, it will take forever and a half.
// decimal places is completely optional, and goes up to 51. by default it uses 10 digits.

// NOTE: KEEP IN MIND THIS IS AN ESTIMATION. IT WILL BE USUALLY ACCURATE TO 10 OR SO DIGITS, BUT PAST THAT WILL TAKE MORE ITERATIONS.

// at the moment, time is bugged. if you run with one thread, it will be accurate,

Threading

So, you want to learn about std::thread added in C++11? This will include that and a small bit on lambdas, which were also added.

How to make two things happen at once:

note: all code samples assume that <thread>, <iostream>, and (later) <future> have been included.

// both threads will run this
void printThreadNum(int num) {

sophec

// add a and b
int binadd(int a, int b) {
    int carry = (a & b) << 1;
    int result = a ^ b;
    if (carry == 0)
        return result;
    else
        result = binadd(result, carry);

    return result;
