These terms are found in Recursion.
1.Base Case:it is the case in recursion where the answer is
known,or we can say the termination condition for a
recursion to unwind back.
For example to find Factorial of num using recursion:
int Fact(int num){
if(num==1 || num==0)//base case
return 1;
else // recursive case:
return num*Fact(num-1);
}
2.Recursive case:It is the case whcih brings us to the
closer answer.
Run Time Stack:It is a system stack us to save the frame
stack of a function every recursion or every call.
This frame stack consists of the return address,local
variables and return value if any.
Tail Recursion:The case where the function consist of
single recursive call and it is the last statement to be
executed.A tail Recursion can be replace by iteration.
The above funtion consists of tail recursion case.
where as the below function does not.
void binary(int start,int end,int el){
int mid;
if(end>start){
mid=(start+end)/2;
if(el==ar[mid])
return mid;
else{
if(el>ar[mid])
binary(mid+1,end,ele);
else
binary(start,mid-11,ele);
}
}
}

Answer / khalith
Base case: A case in recursion, in which the answer is known when the termination for a recursive condition is to unwind back.
Recursive Case: A case which returns to the answer which is closer.
Run-time Stack: A run time stack used for saving the frame stack of a function when every recursion or every call occurs.
Tail Recursion: It is a situation where a single recursive call is consisted by a function, and it is the final statement to be executed. It can be replaced by iteration.
