What is the output for this C++ code ?

Question

int i = 0 ; 
int sum = 0 ;

 while(i<100)
{    
     sum = sum + i ;
     i++;   
}
cout<<sum  ; 

Answer 1

HERE SUM WILL BE 0+1+2+3+.....+99  IS AP SUM ,

here a=0 and Tn=99;

AND AP sum= (n/2)(a+Tn);

Answer would be sum=(100/2) (0+99) = 50*99 =4950.

I think your answer is wrong as 100 is not included in the sum...
