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

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;
}
