Problem:

Write a C function that includes the following sequences of statements:

x = 21;
int x;
x =42;

Run program and explain the results. Rewrite the same code in C++ and Java.

I understand Java:
Looks like this;
Java:
public int myMethod(int x)
{
x = 21;
x = 42;
return x;
}

It will return a value of 42 at the point of call, because the first value of 21 in x gets overwritten by the new value 42
