int m, n;
void w // function prototype
(float&,
float&,
int);
Is the function call w (z*2, y, m); correct? If not, state why not.
3.
B. input
C. intern
D. display E. get 4. What is printed by the program that follows?
#include
using namespace std;
int main ()
{
float bizarre;
float x;
x = 35.8;
cout << bizarre(x);
return 0;
}
float bizarre (float n)
{
cout << n;
return n;
} 5,Refer to the following declarations, how would one assign the value of num to the id component of variable emp2?
struct emprec
{
string name;
int id;
float salary;
};
emprec emp1, emp2;
char ch1;
int num;
bool flag;
A. emprec.id = num;
B. emp2.num = id;
C. emp2.id = num;
D. &emp2.id = num; E. emprec.emp1.id = num; 6.A(n) ____________ file consists of a stream of character codes.
A. binary
B. executable
C. object
D. pointer E. data 7. Processing array elements in order from first to last is called____processing. When the order in which array elements are accessed is not predictable, one is using access.
Explanation / Answer
Easy 1.open() 2 incorrect reason:- it is incorrect because we have only declared the variable x,y,z in the statment float x y z, and we have not defined or initialized these variables with legal values.if we don't intialize or defined a variable, the compiler will not create memory space for it. Since no memory has created for variable x,y,z so we cannnot pass the reference of these variable in function call w(z*2,y,m) 3. A 4. 35.835.8 5.c 6. E 7.sequential
