what do you mean by repeat? If you want it to loop, you would use a while or for loop. For example;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
#include <iostream>
usingnamespace std;
int main()
{
double c, f;
int x = 1;
while(x != 0) {
cout<<"The degrees in celsius: ";
cin>>c;
f = (9/5)*c+32;
cout<<"\n In fahrenheit it is "<<f<<"\n";
cout<<"Enter 0 to quit, 1 to continue:\n";
cin>>x;
}
system ("pause");
return 0;
}
