Question

a) Make a function which returns x/3 with a given integer x.

double third(int x) {

//Complete your code below.

______________________________________

return y;

}

b) Make a program which shows 2 ∗ n with a given user input n.

#include<iostream>

using namespace std;

// Complete the blank.

_______________________

int main(){

int n;

cout<<"Enter:";

cin>>n;

cout<<twice(n);

return 0;

}

int twice(int x){

return 2*x;

}

c) Make a function which returns true if n is positive, otherwise returns false.

________ positive(int n){

if( ) return true;

else return false;

}

Answer 1

a)
double third(int x) {
    double y = x/3.0;
    return y;
}

===================================

b)
#include<iostream>
using namespace std;

int twice(int);
int main(){
    int n;
    cout<<"Enter:";
    cin>>n;
    cout<<twice(n);
    return 0;
}

int twice(int x){
    return 2*x;
}

===================================

c)
bool positive(int n){
if(n>0) 
    return true;
else
    return false;
}
