Question

Here is my code so far:

 #include "stdafx.h"
 #include <iostream>
 #include <string>
 using namespace std;

 int main()
 {
 string exp;
 cout << "Enter a number and raise it to a power" << endl;
 cin >> exp;
 int num = exp[0];
 int pow = exp[2];

 cin.get();
 cin.ignore(256,'\n');
 }

Basically, I’m trying to make a program where you can enter something like “2^5” and it will solve it for you. So far, I have taken the first and third values of the string and called them “num” and “pow”. (Number, Power) If you try something like “cout << num;” it will give you the decimal Ascii value. How do I convert it to a decimal?

Answer 1

    int num;
    char op;
    int pow;
    if ((std::cin >> num >> op >> pow) && op == '^') {
            // do anything with num and pow
    }
