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
<em>for(int i =0;i<len;i++){
</em>
<em> cin>>inpt;
</em>
<em> vect.push_back(inpt);
}
</em>
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++;
}
}
cartesian coordinates for both the carries waves of the same wavelengths and represents the result in total.
