Question

Using C++, change the formatting in this code by using set precision and set width. The decimals should line up.

#include

using namespace std;

int main()
{
int start, end;
int ch=1;

do{
cout<<"Enter starting and ending range";
cin>>start;
cin>>end;
if(end36)
{
cout<<"Invalid range\n";
continue;
}
cout<<"Inches\tCentimeters\n";
cout<<"******\t***********\n";

for(int i=start;i<=end;i=i+6){
cout< }
cout<<"Do you want to continue -1 to quit";
cin>>ch;
}while(ch!=-1);

return 0;
}

#include <iostream>
#include <iomanip>

using namespace std;

int main() {
    int start, end;
    int ch = 1;

    do {
        cout << "Enter starting and ending range";
        cin >> start;
        cin >> end;
        if (end < start) {
            cout << "Invalid range\n";
            continue;
        }
        cout << "Inches\tCentimeters\n";
        cout << "******\t***********\n";

        for (int i = start; i <= end; i = i + 6) {
            cout << setw(10) << setprecision(2) << fixed << left << i << setprecision(2) << fixed << 2.54*i << endl;
        }
        cout << "Do you want to continue -1 to quit";
        cin >> ch;
    } while (ch != -1);

    return 0;
}
