t = a; a = b; b = t; // t is a third integer variable (swap variable) But here's a way without a swap variable, given as as a macro in C: #define SWAP(a,b) { if (a!=b) { a^=b; b^=a; a^=b; }} // Swap macro by XOR Once you define it, you can say swap(x,y) to swap x and y. The numbers kind of flow through each other and end up swapped.
Quicksort in any programming language is an algorithm for sorting data sequences. It is typically implemented as follows (example demonstrates a quicksort of an array of type int). Note that a half-open range, [begin:end), includes the one-past-the-end of the range and is the conventional means of defining a range of contiguous array values. When begin==end, the range is deemed empty. // forward declarations void qsort (int* unsigned); // this is the function you will actually invoke void qsort_rec (int*, int*); // recursive function int* partition (int*, int*); // utility functions... int* select_pivot (int*, int*); void swap (int*, int*); int count (int*, int*); // sort a data sequence of length size void qsort (int* data, unsigned size) { qsort_rec (data, data + size); } // recursively sort the half-open range [begin:end) void qsort_rec (int* begin, int* end) { if (count (begin, end) < 2) return; // end point of recursion int* pivot = partition (begin, end); qsort_rec (begin, pivot); qsort_rec (++pivot, end); } // divide the half-open range [begin:end) into two around a pivot value int* partition (int* begin, int* end) { if (count (begin, end) < 2) return begin; int* pivot = select_pivot (begin, end); swap (begin, pivot); --end; while (begin != end) { while (*(begin) <= *pivot && begin != end) ++begin; while (*pivot < *(end) && begin != end) --end; if (begin!=end) swap (begin, end); } assert (begin==end); // sanity check! swap (pivot, begin); return begin; } // select the median of three from a half-open range [begin:end) int* select_pivot (int* begin, int* end) { int* mid = begin + (count (begin, end) / 2); if (*end<*begin) swap (begin, end); if (*mid<*begin) swap (begin, mid); if (*end<*mid) swap (mid, end); return end; } // swap the values referred to by p and q void swap (int* p, int* q) { if (!p !q) return; // sanity check! int t = *p; *p = *q; *q = t; } // count the elements in the half-closed range [begin:end) int count (int* begin, int* end) { int cnt = 0; int add; if (begin>end) { // swap pointers if the range is reversed int* t = begin; begin = end; end = t; add = -1; // count will be negative } else { add = 1; // count will be positive } while (begin++!=end) cnt+=add; return cnt; }

The rules of an online swap shop are fairly logical; participants are expected to meet their end of the bargain. Communication is often initiated via email or telephone, after which the participants can arrange their own meeting.

Global Swap Shop is when a country sends another country something involving money.
toucans are very multicoloured and their beaks are multicoloured too.

At the Swap Shop. LOL !
