using namespace std;

int main()
{
 stack s;

 cout << "Stack size :: " << s.size() << endl;
 
 for(int i=1; i<=5; i++)
  s.push(i);
 
 cout << "Stack size :: " << s.size() << endl;

 cout << "Elements into Stack :: " << endl;
 while(!s.empty())

  s.pop();
 }

 if(s.empty())
  cout << "Stack is empty..." << endl;
 else
  cout << "Not empty..." << endl;

 return 0;
}

Output

Stack size :: 0
Stack size :: 5
Elements into Stack :: 
5
4
3
2
1
Stack is empty...

take two 2D char array and store the words of each of two input strings. here word means group of "a-z", "A-Z" and "0-9". Also ignore other char.
after that run lcs algo between these two array.
print "blank!" if any of the input is blank line..... if lcs is 0 then print like other non zero answer

1. Use Heron's formula to calculate the area of the triangle
2. r = 2A/(a+b+c);
3. Critical test case. Input : 0 0 0, Output : The radius of the round table is: 0.000

1. Use scanf to take input
2. sort using the sort function of #include<algorithm> header file]
3. Use a trick to print the ages bcz after the last element there will be newline rather than blank space

1. connect the three center of the circles, then u will have a tringle where a = r1+r2, b=r2+r3, c=r3+r1. Find the area of the triangle using heron's formula
2. use cosine formula to find out the angle between the connecting lines and find out the area which of arc 
3. finialy minus these with the value of the triangle and print the value.

Use the following formulas ::
area = (4*sqrt(o*sqrt( o*(o-m1)*(o-m2)*(o-m3) ) ))/3
o = (m1+m2+m3)/2;

do check for invalid triangle. and printf -1.000 for that.

Just run a loop from a to b and add them with another variable s(initial value of s=0). Plz do check for either it is odd number or not.....

There are 2 ways to solve the problem.

One
Using for loop upto no of passes while increasing the value of player no.

Two
Do simple calculation using no of passes, no player & starting point.
