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{
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.
