#include
int main(int argv, char ** argc){
char x = 'm';
float a = 3.14, b = 9.3453, e = 3, f = 1/3;
f = (1.0 / 3);
short c = 6;
std::cerr.write( "x = ", 4);
std::cerr.put(x);
std::cerr.put( '\n');
std::cerr << "x = " << x << std::endl;
std::cout << "a + b + c = " << std::scientific << a + b + c << "
hello World" << std::endl;
std::cout << "a + b + c = " << std::fixed << a + b + c << std::endl;
std::cout << "e * f = " << e << " * " << f << "=" << e * f <<
std::endl;
((std::cout.write("x= ", 3)).operator<<(x)).operator<<(std::endl);
((std::cout.operator<<("x= ")).operator<<(x)).operator<<(std::endl);
std::cout << "x = " << x << std::endl;
}
