Answer:
Jog
Explanation:
The variable options is a list containing 5 string values
options = ["ski", "surf", "jog", "bike", "hike"]
Indexing in python starts from 0 ; hence the index values of the list values are :
0 - ski
1 - surf
2 - jog
3 - bike
4 - hike
The statement ;
print(options[2]) means print the string at index 2 in the list named options
The string at index 2 is jog ;
Hence, the string jog is printed.
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:
i think digital signals
Explanation:
A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
