Answer:
Clara should use computer lenses and artifical tears.
The computer lenses help block blue light from entering your eyes which would help with the headaches and help you focus on something further away. The artificial tears help lubricate dry eyes which prevents or in Clara's case, reduces/relieves eye strain.
Answer:
In C++:
#include<iostream>
#include<vector>
using namespace std;
int main() {
int len;
cout<<"Length: "; cin>>len;
string inpt;
vector<string> vect;
for(int i =0;i<len;i++){
cin>>inpt;
vect.push_back(inpt); }
char ch;
cout<<"Input char: "; cin>>ch;
for(int i =0;i<len;i++){
size_t found = vect.at(i).find(ch);
if (found != string::npos){
cout<<vect.at(i)<<" ";
i++;
}
}
return 0;
}
Explanation:
This declares the length of vector as integer
int len;
This prompts the user for length
cout<<"Length: "; cin>>len;
This declares input as string
string inpt;
This declares string vector
vector<string> vect;
The following iteration gets input into the vector
for(int i =0;i<len;i++){
cin>>inpt;
vect.push_back(inpt); }
This declares ch as character
char ch;
This prompts the user for character
cout<<"Input char: "; cin>>ch;
The following iterates through the vector
for(int i =0;i<len;i++){
This checks if vector element contains the character
size_t found = vect.at(i).find(ch);
If found:
if (found != string::npos){
Print out the vector element
cout<<vect.at(i)<<" ";
And move to the next vector element
i++;
}
}
How efficient well if we are transmitting 6bits and we need 10 to transmit the 6 bits that would be 6/10 = .6 = 60% efficient.
