How would you convert a string to a int?

Answer 1

// In C++

#include <iostream>
#include <string>
using namespace std;

int main()
{
string str = "12345"; // a string of numbers

for (const auto &i : str) cout << (i - '0') << endl;
}

Output:

Answer 2

java

Answer 3

For example:
int age;
double weight, height;

double weightin= weight/2.2;
double heightpo= height*0.39;
double BMR= 6.2*weight + 12.7*height - 6.76*age+66;

how would I convert this using the double.parsedouble() and integer.parseInteger (); ?
