Answer:
The main difference between second generation (2G) and third generation (3G) technology is data. 2G services were developed with mostly voice services in mind, but are capable of providing relatively slow (14.4kbps) speed data services.
Answer:
The function in Python is as follows:
def MaxValue(userNum1, userNum2):
if userNum2>userNum1:
return userNum2
else:
return userNum1
Explanation:
This defines the function
def MaxValue(userNum1, userNum2):
This returns userNum2 if userNum2 is greater than userNum1
<em> if userNum2>userNum1:</em>
<em> return userNum2</em>
If otherwise, this returns userNum1
<em> else:</em>
<em> return userNum1</em>

Answer:
True
Explanation:
I took the test a little while ago
In C, you deal with a string always via a pointer. The pointer by itself will not allocate memory for you, so you'll have to take care of that.
When you write char* s = "Hello world"; s will point to a "Hello world" buffer compiled into your code, called a string literal.
If you want to make a copy of that string, you'll have to provide a buffer, either through a char array or a malloc'ed bit of memory:
char myCopy[100];
strcpy(myCopy, s);
or
char *myCopy;
myCopy = (char*)malloc( strlen(s) + 1 );
strcpy(myCopy, s);
The malloc'ed memory will have to be returned to the runtime at some point, otherwise you have a memory leak. The char array will live on the stack, and will be automatically discarded.
Not sure what else to write here to help you...
