Answer:
a) the Statement is Invalid
b) the Statement is Invalid
Explanation:
a)
lets Consider, s: student of my class
A(x): Getting an A
Let b: john
I have a student in my class who is getting ab A: Зs, A(s)
John need not be the student i.e b ≠ s could be true
Hence ¬A(b) could be true and the given statement is invalid
b)
Lets Consider G: girl scout
C: selling 50 boxes of cookies
P: getting prize
s: Suzy
Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)
Suzy, a girl scout, got a prize: s ∈ G, P(s)
since P(s) is true, C(s) need not be true
Main Reason: false → true is also true
Therefore the Statement is Invalid
Answer:
#include <iostream>
#include <string>
#include <stack>
#include <math.h>
using namespace std;
int main() {
string s;
double n=0;
int position=0;
stack<int> wholeNumbers;
cout<<"Enter a decimal number:";
cin>>s;
string::iterator counter = s.begin();
while(*counter!='.' && counter!=s.end()){
wholeNumbers.push(*counter-48);
counter++;
position=position+1;
}
for(int i=0;i<position;i++){
n=n+(wholeNumbers.top()*pow(10,i));
wholeNumbers.pop();
}
position=-1;
if(counter!=s.end()){
counter++;
}
while(counter!=s.end()){
n=n+((*counter-48)*pow(10,position));
position=position-1;
counter++;
}
cout<<n;
}
Explanation:
- Inside the while loop, push the push a number to the wholeNumbers stack by subtracting it with 48.
- Increment the counter and position variable by 1 inside the while loop.
- Count the number of digit, push each digit to top of stack and find the end of the number,
- Run a for loop up to the value of position variable and pop a value from the wholeNumbers stack.
Answer:
Mars loses its atmosphere faster, because there's less gravity to hold on to it. It goes through the loss of atmosphere faster than earth does
