#include<iostream> using namespace std; int main() { int i,sum=0; cout<<" enter numbers between 100 & 130 which are divisible by 9"<<endl; i=101; do { if(i%9==0) { cout
<<"number divisible by 9 is : "<<i<<endl; sum=sum+i; } i++; } while(i<130); cout<<"the sum of all numbers divisible by 9 is: "<<sum; } |
Output
Please enter numbers between 100 & 130 which are divisible by 9:
number divisible by 9 is: 108
number divisible by 9 is : 117
number divisible by 9 is: 126
the sum of all numbers divisible by 9 is: 351
