Question

It’s a C++ question

Then the output from the program should be :

r1 = 2

r2 = 18

r3 = 25

(note : there are no spaces in the output and each line ends with a newline )

Answer 1

If you have any doubts, please give me comment...

#include<iostream>

#include<cmath>

using namespace std;

int main(){

int x, y, z, r1, r2, r3;

cin>>x>>y>>z;

r1 = 4*pow(x,3) - 5*pow(y,2) + 3*z;

r2 = r1 + 7*pow(x,3) - 2*pow(y,2) + 11*z;

r3 = r2 - 9*pow(x, 3) + 22*pow(y, 2) - 6*z;

cout<<"r1="<<r1<<endl;

cout<<"r2="<<r2<<endl;

cout<<"r3="<<r3<<endl;

return 0;

}
