Answer:
Let P(x) = x is in the correct place
Let Q(x) = x is in the excellent place
R(x) denotes the tool
Explanation:
a) Something is not in the correct place.
P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:
∃x¬P(x)
b) All tools are in the correct place and are in excellent condition.
R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:
∀ x ( R(x) → (P(x) ∧ Q(x))
c) Everything is in the correct place and in excellent condition.
Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧ means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:
∀ x (P(x) ∧ Q(x)
Answer:
The program written in C++ is as follows'
#include<iostream>
using namespace std;
int main()
{
string names[3];
cout<<"Please enter three names: "<<endl;
for (int i = 0; i< 3;i++)
{
cin>>names[i];
}
for (int i = 2; i>= 0;i--)
{
cout<<names[i]<<endl;
}
return 0;
}
Explanation:
This line declares an array for 3 elements
string names[3];
This line prompts user for three names
cout<<"Please enter three names: "<<endl;
This following iteration lets user input the three names
for (int i = 0; i< 3;i++) { cin>>names[i]; }
The following iteration prints the three names in reverse order
for (int i = 2; i>= 0;i--) { cout<<names[i]<<endl; }
