C++ examples for Data Type:double
Read three double-precision, floating-point numbers and passes them to a function to get the smallest number.
#include <iostream> double minimum(double, double, double); int main(int argc, const char *argv[]) { double d1, d2, d3; std::cout << "Enter three double values: "; std::cin >> d1 >> d2 >> d3; std::cout << "Smallest: " << minimum(d1, d2, d3) << std::endl; return 0;//from www.ja va 2s .c o m } // finds and returns the smallest of 3 values double minimum(double d1, double d2, double d3) { double minimum = d1; if (d2 < minimum) minimum = d2; return (d3 < minimum) ? d3 : minimum; }
