}
Example 2: function declerations in C++
#include <iostream>
#include <stdlib.h>
#include <iomanip>
#include <fstream>
using namespace std;
void function_one(double, double, double);
int main() {
double r1 = 1.0;
double r2 = 2.0;
double x = 0.0;
function_one(r1, r2, x);
return 0;
}
void function_one(double rmin, double rmax, double x0) {
cout << "Function got called" << endl;
}
