====== Pre- and post-increment operators ====== In this example, we implement the pre- and post-increment operators as functions to better understand their semantics. The code is in C++. <sxh cpp> #include <cstdlib> #include <iostream> using namespace std; int postIncrement(int & c) { int x = c; c = c + 1; return x; } int preIncrement(int & c) { c = c + 1; return c; } void print(int c, int b) { cerr << "c=" << c << "b=" << b << endl; } int main() { { int c = 1; int b = (c++) + 2; print(c, b); b = ++c + 2; print(c, b); b = -c++; print(c, b); b = -++c; print(c, b); } printf("\n"); { int c = 1; int b = postIncrement(c) + 2; print(c, b); b = preIncrement(c) + 2; print(c, b); b = -postIncrement(c); print(c, b); b = -preIncrement(c); print(c, b); } return EXIT_SUCCESS; } </sxh>
