Discuss operator precedence in C programming with examples
Answers
Answer:
See picture for the operator precedence.
A very common pitfall is the << (shift) operator.
It has lower precedence than, for instance, the + operator, so a statement like:
int a = 3;
int c = a << 2 + 1;
will produce a different result than:
int c = (a << 2) + 1;
The first will evaluate to c = a<<3.

What is randint method?The randint() method is a method or function in the random python module. It is used to get or return an integer number within a specified range.
To use the method, the module must be imported into the python file with the "import random" statement, then the method is referenced using dot notation and specifying the range of integer numbers. Syntax: random. randint first_number, last_number note that the last number in the range is inclusive in the selection.

The one that is software threat is an overflow attack. The correct option is b.
What is a software threat?Software threats are harmful programs and pieces of code that can harm your computer and steal your personal or financial data. Because of this, these harmful programs are frequently referred to as malware (short for "malicious software").
Nowadays, many software vulnerabilities explicitly target smartphones, making cybersecurity strategies based on desktop PCs ineffective in some cases.
Apps, and smartphone viruses, are merely mobile versions of viruses that target your desktop or laptop computer. Blue jacking is the practice of sending unwanted or unsolicited Bluetooth messages to complete strangers.

A game is played by moving a game piece left or right along a horizontal game board. The board consists of spaces of various colors, as shown. The circle represents the initial location of the game piece.
Yellow Black Green Green Red Yellow Black Black Yellow Black
The following algorithm indicates how the game is played. The game continues until the game is either won by landing on the red space or lost when the piece moves off either end of the board.
Step 1: Place a game piece on a space that is not red and set a counter to 0.
Step 2: If the game piece is on a yellow space, move the game piece 3 positions to the left and go to step 3. Otherwise, if the game piece is on a black space, move the game piece 1 position to the left and go to step 3. Otherwise, if the game piece is on a green space, move the game piece 2 positions to the right and go to step 3.
Step 3: Increase the value of the counter by 1.
Step 4: If game piece is on the red space or moved off the end of the game board, the game is complete. Otherwise, go back to step 2. If a game is begun by placing the game piece on the rightmost black space for step 1, what will be the value of the counter at the end of the game
Required:
If game piece is on the red space or moved off the end of the game board, the game is complete. Otherwise, go back to step 2. If a game is begun by placing the game piece on the rightmost black space for step 1, what will be the value of the counter at the end of the game?
Answers
The value of the counter of the given algorithm at the end of the game is; 4
How to solve Algorithms?
From the attached table, we see the algorithm of the given game.
Now, the black circle is initially under the column black.
From the given conditions, step 1 says since the space is not red we should set a counter to 0. Thus, the counter will be set to 0.
Since the game piece is under the black column, according to step 2, we will move the game piece 1 position to the left and go to step 3.
By moving one position to the left, the game piece will be under the yellow column. We now increase the counter by 1 to 1.
According to step 2, at yellow, we move the game piece 3 places to the left and it will land on yellow and we increase the counter to 2 and move 3 places to the left again to stop at green.
At green we increase the counter to 3 and then move two spaces to the left which is the left end of the board and we will increase the counter to 4 and the game will be complete according to step 4.

Identify science and technology policies that could be adapted or implemented in the Philippines?
Answers
Answer:
In the Philippines, universities dominate the research arena. So you have scientists who make research for the sake of research.
The private sector may or may not adopt the research. If a research in UP finds a molecule that may kill cancer, we are not sure whether that research will be adopted or not.
We are not sure if that research will be continued to actual creation of a medicine of cancer. This is because our scientists are working in universities and not in actual pharma companies.
In other countries, the scientists build their own companies. So their research go from drug development to actual manufacturing and marketing of medicines.
So when they start a research, you know that in the next 5 to 10 years, these scientists will produce drugs which the public can benefit from.
This is why the Philippine research is not thriving as it should. Our government should support our start ups.
When scientists are given grants for research, they should also be given grants to start their company. Unfortunately, start up grant is not a function of the DOST. It is of the DTI.
