Question

Implement C++ program for each of the following.
Let D = [-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36] Each answer is either True or False. If False, give example
of number(s) that make it False. i.e. The Counterexample. ∀x∈D, if x is odd then x > 0

Let D = [-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36] Each answer is either True or False. If False, give example
of number(s) that make it False. i.e. The Counterexample. ∀x∈D, if x is less than 0 then x is even.

C++ Program:

#include<iostream>
using namespace std;

void function1(int D[]){
int flag=0;
for(int i=0;i<11;i++){
if(D[i]%2!=0)
{
if(D[i]<=0){
if(flag==0){
cout<<"The number(s) that make Statement 1 false: ";
flag=1;
}
cout<<D[i]<<" ";
}
}
}
if(flag==0)
cout<<"Statement 1 is True";
cout<<"\n\n";
}

void function2(int D[]){
int flag=0;
for(int i=0;i<11;i++){
if(D[i]<0)
{
if(D[i]%2!=0){
if(flag==0){
cout<<"The number(s) that make Statement 2 false: ";
flag=1;
}
cout<<D[i]<<" ";
}
}
}
if(flag==0)
cout<<"Statement 2 is True";
cout<<"\n\n";
}

void function3(int D[]){
int flag=0;
for(int i=0;i<11;i++){
if(D[i]%2==0)
{
if(D[i]>0){
if(flag==0){
cout<<"The number(s) that make Statement 3 false: ";
flag=1;
}
cout<<D[i]<<" ";
}
}
}
if(flag==0)
cout<<"Statement 3 is True";
cout<<"\n\n";
}

void function4(int D[]){
int flag=0;
for(int i=0;i<11;i++){
if(D[i]%10==2)
{
int temp=D[i]/10;
temp=temp%10;
if(temp!=3&&temp!=4){
if(flag==0){
cout<<"The number(s) that make Statement 4 false: ";
flag=1;
}
cout<<D[i]<<" ";
}
}
}
if(flag==0)
cout<<"Statement 4 is True";
cout<<"\n\n";
}

void function5(int D[]){
int flag=0;
for(int i=0;i<11;i++){
if(D[i]%10==6)
{
int temp=D[i]/10;
temp=temp%10;
if(temp!=1&&temp!=2){
if(flag==0){
cout<<"The number(s) that make Statement 5 false: ";
flag=1;
}
cout<<D[i]<<" ";
}
}
}
if(flag==0)
cout<<"Statement 5 is True";
cout<<"\n\n";
}

int main(){
int D[11]={-48,-14,-8,0,1,3,16,23,26,32,36};
function1(D);
function2(D);
function3(D);
function4(D);
function5(D);
return 0;
}

Output:
