I want to set precision to 2 with the results. Does that mean that I have to put << setprecision (2) << after every weight on each planet or is there something easier I can do?

#include<iostream> 
#include<cmath>

using namespace std;

int CheckWeight(int weight, string Planet);

int main()
{
	int weight,res;
	string planetName;
	
	do{
		cout << "Please enter your weight of your object to the nearest whole number." <<endl;
		cin >> weight;}
	while(cin.good()==false);
	cout << " " << endl;
	do{ 
		cout << "Please enter a planet name from the following list." << endl;
		cout << "Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune" << endl;
		cin >> planetName;
		cout << " " << endl;
		// Call function to check weight
		res = CheckWeight(weight, planetName);
	}while(res==1);
	system("PAUSE");
	return 0;
}// end main()

// Function for calculating weight

int CheckWeight(int weight, string Planet)
{
	int Result=0;
	if(Planet== "Mercury"){
		cout << "Your weight on Mercury is " << (weight*0.4155)<< endl;
	}
	else if(Planet== "Venus"){
		cout << "Your weight on Venus is " << (weight*0.8975)<< endl;
	}
	else if(Planet== "Earth"){
		cout << "Your weight on Earth is " << (weight*1.0)<< endl;
	}
	else if(Planet== "Mars"){
		cout << "Your weight on Mars is " << (weight*0.3507)<< endl;
	}
	else if(Planet== "Jupiter"){
		cout << "Your weight on Jupiter is " << (weight*2.5374)<< endl;
	}
	else if(Planet== "Saturn"){
		cout << "Your weight on Saturn is " << (weight*1.0677)<< endl;
	}
	else if(Planet== "Uranus"){
		cout << "Your weight on Uranus is " << (weight*0.8947)<< endl;
	}
	else if(Planet== "Neptune"){
		cout << "Your weight on Neptune is " << (weight*1.1794)<< endl;
	}
	else{
		cout << "You entered a wrong planet name. Please try again " << endl;
		cout << "Please try again " << endl;
		Result=1;
	}
	return Result;

The precision function could be useful here:

cout.precision(2);
cout<<2.234134<<endl;
cout<<2.343144<<endl;

Outputs:
2.2
2.3

In other words, using cout.precision(X) sets the precision of cout to X and it stays that way until cout.precision(Y) is called, then the precision is set to Y.

Alse try to avoid using system("pause"), try using cin.get() instead.
