Question 5 What is the output of the following code snippet?
#include <iostream> using namespace std; int main()
{
int value = 3; value++; cout << value << endl; return 0;
}

Question 6 Which of the following options is valid with reference to the code snippet?
#include <iostream> using namespace std; int main()
{
double d = 45.326; double r = d % 9.0; cout << r; return 0;
}
Answer The value inside the variable r will be 0.326 The value inside the variable r will be 5.036 Variable r has to be defined as an integer as the % operator always returns an integer The assignment statement for variable r is wrong, as the % operator expects integer values as operands
