Hey friends please explain me the code and say why its output is 9...

Question

include <iostream>
using namespace std;

int main() {
int sum =0;
int count=1;
while(sum<8){
sum+=count;
count =count+2;
}
cout<<sum;
return 0;
}
//out put is 9

Answer 1

in the while loop
* the first loop
sum = 0 + 1 = 1;
count = 1 + 2 = 3;
*the second loop
sum = 1 + 3 = 4;
count = 3 + 2 = 5;
*the third loop
sum = 4 + 5 = 9;
count = 5 + 2 = 7;
at this time the while loop stop because the value of sum is 9 so it is greater than 8.
so the final value of sum is 9
and the final value of count is 7
