Here is how we do :

using namespace std;

float add(float a, float b){
          return a+b;  
}

int main(){

float num1;
float num2;    

while(true) 
{
    cout<<"add...enter digits \n";
    cout<<"first digit: ";
    cin>>num1;

    cout<<"\nSecond number: ";
    cin>>num2;

    cout<< "your sum is: "<> ch;
    if (ch == 'Y' || ch == 'y')
        continue;
    else
        break;
}

return 0;
