Return Value Of Functions
#include <iostream> #include <iomanip> using namespace std; double area(double, double); int main() { double x = 3.5, y = 1.2, res; res = area( x, y+1); cout << fixed << setprecision(2); cout << " The area of a rectangle " << " with width " << setw(5) << x << " and length " << setw(5) << y+1 << " is " << setw(5) << res << endl; return 0; } double area( double width, double len) { return (width * len); }
