Property Value

Description
html markup
shown to student

In the example below a divide-by-0 will cause the program to crash if the user enters the value of <tt>2</tt>

In subsequent exercises we will see how to fix this problem.

Template / Reference solution

#include <iostream>
#include <stdexcept>
using namespace std;
int divide(int num, int denom)
{
if(denom == 0)
{
cout << "Denom is 0" << endl;
}
return(num/denom);
}
int f1(int x)
{
return divide(x, x-2);
}

int main()
{
int res = -1, a;
cout << "Enter: " << endl;
cin >> a;
res = f1(a);
cout << res << endl;
return 0;
}

Java test suite
See manual

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]

[{"stdin":"2"}]
C++ test suite
See manual

Forbidden substrings
json list of strings
e.g. ["for","while"]

remove
Solution visibility remove
Java imports
json list of importables
e.g. ["java.util.*"]

remove
Override Java classname
else defaults to
websheet name
remove
Dependent on other websheets?
json list of websheet names in this folder
e.g. ["DataStructure"]

remove
Is example?
i.e., just a demo
remove
Add compiler flag(s)
json list of flags
e.g. ["-Wno-unused-variable"]

remove
Remove default compiler flag(s)
json list of flags
see default_cppflags
e.g. ["-Wno-write-strings"]
