Answer 1

Answer:

Below program is in C++ Programming Language

Explanation:

Code explanation is in comments, the line starts with // .

// Import all necessory files

#include<iostream>

#include<string>

#include<sstream>

using namespace std;

int main()

{

//Declaring input string to get data from user

string myinput="";

// getline will get input string from user through command prompt

getline(cin, myinput);

//stringstream will be used to get one by one inputed number //seperated by space

//stringS is the name we set for stringstream

stringstream stringS(myinput);

// num will be used to get space seperated number from stringstream

int num = 0;

int sum=0;

// we need to count total numbers enterd by user to get the average

int count=0;

// this if is to prevent any error if user does not provide any number

if(myinput == ""){

cout<< "Nothing entered";

return 0;

}

// while loop iterates up to total inputed numbers entered by user

while (stringS >> num) {

sum += num;

count++;

}

// Output the desired result

cout << "Sum :"<<sum << "\n";

cout << "Average :" << sum/count <<endl;

return 0;

}
