Find and write the output of the following C++ program code:
Note: Assume all required header files are already included in the program.
void Revert(int &Num, int Last = 2)
{
Last = (Last % 2 ==0) ? Last + 1 ; Last - 1:
for (int C=1; C< Last; C++)
Num+=C;
}
void main ()
{
int A = 20, B= 4;
Revert(A, B);
cout<<A<<"&" <<B<<end1;
B--;
Revert(A, B);
cout<<A<<"#"<<B<<end1;
Revert(B);
cout<<A<<"#"<<B<<end1;
}
