Can someone explain me how the output is coming to 1890?

Question

#include<iostream>
using namespace std;
float value = 900;
void local (int T)
{
int result = 0;
for ( int I=0; I<T; I++)
result+=I;
cout << value + result ;
}
int main()
{
local(45);
return 0;
}

Answer 1

Thanks for answering, Not getting how is 990 coming ( I am new to functions) all I understood is float value = 900 is global my question is the loop

Answer 2

Dipanjan Basu , first the loop calculates the following sum 0+1+2+3+...+44 => 990. Next adding 900 and display it 990 + 900 => 1890.
