7. (TCO 11) What type of error will this code produce?
int n[30], i;
for(i = 0; i <= 30; ++i)
n[i] = i; (Points : 3)
No compiler errors will be reported.
A compiler error is generated since there are no braces {} with the for loop.
A runtime error may occur because we are out of bounds on the array.
No compiler errors will be reported, but a runtime error may occur because we are out of bounds on the array.
8. (TCO 11) Is it possible to write code in this manner for a C++ program?
char auto;
cout << "what kind of automobile do you have?";
cin >> auto;
char cars[auto]; (Points : 3)
Yes, this is perfectly acceptable C++ code.
No, the array dimension cannot be a variable.
The compiler would report that there is an illegal use of a keyword.
Yes, this is perfectly acceptable C++ code, but the comopiler would report that there is an illegal use of a keyword.
9. (TCO 11) What is wrong with this code?
WriteGreeting(char greetings[ ]);
int main()
{
char greetings[3][10]= {"hello", "howdy', "hi"} ;
WriteGreeting(greetings);
return 0;
}
WriteGreeting(char greetings[ ] )
{
for(int I = 0; I < 3; ++I)
cout<<greeting[I];
} (Points : 3)
The function prototype has a number in the second array dimension brackets.
There are only three items in the array list.
The code is correct.
The function header needs the second array dimension size specified as in prototype.
10. (TCO 12) Assuming that t is an array and tPtr is a pointer to that array, which expression refers to the address of element 3 of the array? (Points : 3)
*( tPtr + 3 )
tPtr[ 3 ]
&t[ 3 ]
*( t + 3 )
