int DFS(a, b,c,d)
{
first=a+b;
second=c+d;
return(first,second);
}
solution, cost_limit = DFS(a, b,c,d);
can I do something like this ? and how?

Example - Declaring multiple variables in a statement and assigning values. If your variables are the same type, you can define multiple variables in one declaration statement. You can also assign the variables a value in the declaration statement.
Multiple variable assignment is also known as tuple unpacking or iterable unpacking. It allows us to assign multiple variables at the same time in one single line of code. In the example above, we assigned three string values to three variables in one shot. As the output shows, the assignment works as we expect.
We can assign values to multiple variables at once in a single statement in Swift. We need to wrap the variables inside a bracket and assign the values using the equal sign = . The values are also wrapped inside a bracket.
Yes, by using the comma operator. E.g. for (i=0, j=0; i<10; i++, j++) { ... }
In C++11 you can use the tuple types and tie for that.
#include <tuple>
std::tuple<int, int> DFS (int a, int b, int c, int d)
{
return std::make_tuple(a + b, c + d);
}
...
int solution, cost_limit;
std::tie(solution, cost_limit) = DFS(a, b, c, d);
With C++17, you can unpack a pair or a tuple
auto[i, j] = pair<int, int>{1, 2};
cout << i << j << endl; //prints 12
auto[l, m, n] = tuple<int, int, int>{1, 2, 3};
cout << l << m << n << endl; //prints 123
