Answer:
The program is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
int n;
cout<<"Elements: ";
cin>>n;
vector <int>vectnum;
int numInp;
for (int i = 1; i <= n; i++){ cin>>numInp; vectnum.push_back(numInp); }
int big, secbig;
big = vectnum.at(0); secbig = vectnum.at(1);
if(vectnum.at(0)<vectnum.at(1)){ big = vectnum.at(1); secbig = vectnum.at(0); }
for (int i = 2; i< n ; i ++) {
if (vectnum.at(i) > big) {
secbig = big;;
big = vectnum.at(i);
}
else if (vectnum.at(i) > secbig && vectnum.at(i) != big) {
secbig = vectnum.at(i);
}
}
cout<<"Second Largest: "<<secbig<<endl;
int small, secsmall;
small = vectnum.at(1); secsmall = vectnum.at(0);
if(vectnum.at(0)<vectnum.at(1)){ small = vectnum.at(0); secsmall = vectnum.at(1); }
for(int i=0; i<n; i++) {
if(small>vectnum.at(i)) {
secsmall = small;
small = vectnum.at(i); }
else if(vectnum.at(i) < secsmall){
secsmall = vectnum.at(i); } }
cout<<"Second Smallest: "<<secsmall;
return 0;
}

Metals are the greatest conductors of electricity. metalloids are fair conductors because they have features of both nonmetals and metals. Nonmetals are poor conductors.
I believe this is an example of a Wireless Personal Area Network (WPAN). This type of network provides a low range wireless network that can interconnect devices near each other. So, Bluetooth devices such as a Bluetooth headset would be an example of WPAN.

<u>Answer:</u>
I am writing <em>partial code in</em> <em>c++ to calculate weighted average</em>. The weighted average should be calculated based on multiplying the test score and its <em>respective weight and finally add all the test score.</em>
<u>Explanation:</u>
<em>int arrtestscore[100];</em>
<em>int arrweight[100];</em>
<em>int n;</em>
<em>double weightedavg;</em>
<em>cout<<”Enter the number of test score for which weighted average needs to be calculated”;</em>
<em>cin>>n;</em>
<em>for(int x = 0; x <n;x++)</em>
<em>{</em>
<em> cout<<”Enter test score :” + (x+1) ;</em>
<em> cin>>arrtestscore[x];</em>
<em> count<<”Enter the respective weight:”;</em>
<em> cin>>arrweight[x];</em>
<em>}</em>
<em>for (int i=0; i<n;i++)</em>
<em>{</em>
<em> weightedavg = weightedavg + (arrtestscore[i] * arrweight[i])</em>
<em>}</em>
<em>cout<<”weighted average = “ <<weightedavg; </em>
