Answer:
The answer to the given question is the option "(i)".
Explanation:
In this question, the correct option is the "(i)" because In this method definition we use the super keyword. It refers to the parent's class. In this method, we use the superclass to call the above (parent) class method. and if we choose the option (ii), It will not call the parent class. That's why we use the option (i) which is correct.
Answer:
#include <stack>
#include<iostream>
#include<fstream> // to read imformation from files
#include<string>
using namespace std;
int main() {
stack<string> data;
ifstream inFile("postfix.txt");
string content;
if (!inFile) {
cout << "Unable to open file" << endl;
exit(1); // terminate with error
}
while (getline(inFile, content)) {
data.push(content);
}
inFile.close();
return 0;
}
Explanation:
You were very close. Use the standard <stack> STL library, and make sure the stack elements are of the same type as what you're trying to add, i.e., std::string.
Closed the program? Or at least, started to close the program. Hopefully she'll get a prompt to save any unsaved work.
Answer:
A function is a pre-programmed calculation, whereas a formula is a user-defined calculation. A single function could be used in a formula.
Explanation:
if you add =AVERAGE(A1:A56), that is a formula, using the AVERAGE function. If you enter =SUM(G4+A5) - 25 * MIN(B3:B6), that is a formula which uses both the SUM function and the MIN function, as well as standard mathematical operators (-, +, *).
