The answer is D) Projector because with a projector, its in the name project so it can anything u put on their, and put it on a virtual screen that can be put on a wall, so everyone can see.
Answer:
for (scores.Entry<String, Integer> entry : scores.entrySet()) {
int value=0; String key="Rambo";
String k = entry.getKey();
int v = entry.getValue();
if (v>value)
{
value =v;
}
else
{
value=value;
}
}
for( scores.Entry<String, Integer> entry : scores.entrySet())
{
if( entry.getValue()==value)
System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}
Explanation:
The above scores are an object of Map type. And this is a parameter of findUopStudent function. So scores is a Map, and entry is an item. And we get its key and value. Now we compare each value using senteniel method and find the maximum value. Now we iterate through the scores using for the look and check the value of each entry against the maximum value found, and we print out the entry with maximum value. And that is the top student, which is required.
Answer:
B. 1 6 3
Explanation:
Given function definition for calc:
void calc (int a, int& b)
{
int c;
c = a + 2;
a = a * 3;
b = c + a;
}
Function invocation:
x = 1;
y = 2;
z = 3;
calc(x, y);
cout << x << " " << y << " " << z << endl;
- Since x is passed by value, its value remains 1.
- y is passed by reference to the function calc(x,y);
Tracing the function execution:
c=3
a=3
b=c+a = 6;
But b actually corresponds to y. So y=6 after function call.
- Since z is not involved in function call, its value remain 3.
So output: 1 6 3
Answer:
Option D. float is the correct answer.
Explanation:
Decimal number contains decimal point. Out of all the given data types, float data type store the number with decimal point.
As the number has to be further used for calculations float ahs to be used. Because the numbers can also be stored in string but cannot be used for further calculations.
Hence,
Option D. float is the correct answer.
