Which statement about an interpreter is correct?

It translates and executes code statement by statement, so an error on a later line may not be reported until execution reaches it
It reports all syntax errors in the whole program before executing any line
It produces a standalone executable file that runs without the interpreter
Interpreted programs always run faster than compiled programs

It compiles the source to bytecode, which the Python virtual machine then executes
It compiles the source directly to native machine code
It interprets raw source text line by line with no compilation step
It converts the code to Java bytecode and runs it on the JVM

In standard C++, what happens when an integer is divided by zero (int x = 5 / y; with y == 0)?

The compiler always refuses to compile the program
A std::runtime_error exception is always thrown
The result is always 0
Undefined behavior: the standard does not guarantee any exception
