Homework

Question

The picture link is my homework from my professor at the university and I do not know how to solve the duty. All that is required is the work of the text to be answered, such as in the picture, and it must be solved because it has 5 marks

Answer 1

It's not that difficult. No one here will write the complete code for you, we all have real lives and duties :P
But this will help you to get started:
First, how to create a matrix...
Second, how to create random int values...
Then you need to modify the values on certain conditions, that should be easy when you mastered the first two tasks.
Fourth, easy if you managed the third task, two simple nested for loops will do the trick.
Just post your code when you're stuck at any point and someone will help you.

Okay, fair enough :)

Answer 4

Keep in mind plagarism is academic dishonesty, and could get you a failing grade or kicked out of university. You should not copy the solution Andrea gave.

Answer 5

I'm not good in C++ but I'll try to find examples on the playground which you can use to get started.

Answer 6

Rrestoring faith he should try to understand it...but if he is going to CTRLC CTRLV he won't go far away in life...programming is not copy & paste

Answer 7

The instructions basically say to just iterate over each element. If an element is even, multiply it by 2. If an element is odd, multiply it by -1 (change its sign). After that, sum up each row for the answer.
For example, let's say one of your rows is [4, -1, 3]. 4 is even, so you multiply it by 2. That gives you 8. -1 is odd, so you multiply it by -1. That gives you 1. 3 is odd, so you multiply it by -1. That gives you -3. If you sum up "8 + 1 - 3", you will get 6.
You do that for each row. You can achieve this easily with a nested for-loop.

Answer 8

You may want to look into using arrays and a few if statements here a link I just pulled from google on arrays also see the other stuff like working with for loops.
