Write a C++ program to find the number and sum of all integer between 100 and 200 which are divisible by 9 with constructor destructor.

## C++ sum of all integer divisible by a number with constructor destructor

//Write a program to find the number and T4Tutorials_Sum of all integer between 100 and 200 which are divisible by 9. //constructor & destructor #include<iostream> using namespace std; class number { public: number(int i,int T4Tutorials_Sum) { cout<<"numbers that are divisible by 9 between 100 and 200\n"; for(i=101; i<200; i++) if(i%9==0) { cout<<"numbers divisble by 9 is= "<<i<<endl; T4Tutorials_Sum=T4Tutorials_Sum+i; } cout<<"T4Tutorials_Sum of all numbers divisible by 9 is= "<<T4Tutorials_Sum<<endl; } ~number() { cout<<"\n destructor completed its work to free up memory"<<endl; } }; int main() { number f(101,0); }

**Output**
