Question
Use the following code to answer the question:
#include <iostream>
using namespace std;
void foo(int[], int, int&);
void boo(int[], int[], int);
int main()
{
const int SIZE = 5;
int dataArray[SIZE] = { 1,2,6,3,10 };
int x = 0;
int resultArray[SIZE] = {};
foo(dataArray, SIZE, x); //--------1
cout << x; //--------2
boo(dataArray, resultArray, SIZE); //---------3
system("pause");
return 0;
}
void foo(int a[], int length, int& y)
{
y = a[0];
for (int i = 1; i < length; i++)
{
if (y < a[i])
y = a[i];
}
}
void boo(int a[], int b[], int length)
{
for (int i = 0; i < length; i++)
b[i] = a[i] * a[i];
}
Question:
Given the above code which of the following parameters are passed as value parameters in the statement labeled //----3 above
a) dataArray
b) resultArray
c) SIZE
d) All of the above
e) None of the above
Explanation / Answer
Ans:
E)None of the above
Explanation:
value parameters is a formal parameter.Value parameters are parameters as they appear in function declarations.
A parameter declared with no modifiers is a value parameter. A value parameter corresponds to a local variable that gets its initial value from the corresponding argument supplied in the method invocation.
void foo(int[], int, int&);(this is value parameter)
void boo(int[], int[], int);(this is value parameter)
