Question

Correct and complete this C++ program. You are not allowed to include a directory nor changing a variable type or a loop syntax. Stick on the number of lines.

#include<iostream>

using namespace std;

int main ()

{

int N1, N2;

int power;

cout<<"Please enter N1 and N2 in order to calculate N1^N2. N1 should be a positive number. N2 should be between -9 and 9.\n";

cin>>N1>>N2;

while (…………..)

{

cout<<………………………………………….

cin>>………………………………………….

}

while (…………..)

{

cout<<………………………………………….

cin>>………………………………………….

}

……………………………………………..

if(power>0)

{

for(………… ; ………… ; …………)

………………………………………….

cout<<………………………………

}

else if(power<0)

{

for(………… ; ………… ; …………)

………………………………………….

cout<<………………………………

cout<<………………………………

return 0;

}

Answer 1

Code

#include<iostream>

using namespace std;

int main ()

{

int N1, N2;

int power;

cout<<"Please enter N1 and N2 in order to calculate N1^N2. N1 should be a positive number. N2 should be between -9 and 9.\n";

cin>>N1>>N2;

while (N1<0)

{

cout<<"N1 cannot be negative , must be >=0 , Please enter again\n";

cin>>N1;

}

while (!(N2>=-9 && N2<=9))

{

cout<<"N2 must lie between -9 and 9, Please enter again\n";

cin>>N2;

}

power =N2>=0?1:-1;

if(power>0)

{

for(int i=N2 ; i>0 ;i--)

power =power * N1;

cout<<"\nPower : "<<power;

}

else if(power<0)

{

for(int i=N2 ;i<0 ; i++)

power =power*N2;

cout<<"\nPower : "<<(-1/power);

}

else

cout<<"\nPower : "<<power;

return 0;

}
