1. How do convert strings inside a vector to integers and then find the average of set of their values
in C++?
Solution
Answer:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main(){
int n, i;
string input;
getline(cin, input);
stringstream stream(input);
float num[100], sum=0.0, average;
getline(cin,num);
stringstream stream1(num);
cout << "Enter the numbers of data: ";
cin >> n;
while (n>100 || n<=0)
{
stream >> n;
if(!stream)
break;
cout << "Integer Detected: " << n << " ";
}
for(i=0; i<n; ++i)
{
cout << i+1 << ". Enter number: ";
stream1>> num[i];
sum+=num[i];
}

2. average=sum/n;
cout << "Average of integers is :" << average;
return 0;
}
