Hi mantastrike;

There is no need to thank me. I am here to help, you have asked so I will. Because you are a polite and obviously thoughtful person I am making an effort to change your mind.

Yeah I know, but there are a lot of thing going on so I was not able to do this.

You are placing minutiae ahead of your studies. Ahead of your future. Ahead of your potential. Whether it is a girl, partying or even a job, it takes second to your education. Believe me I know. I am going to do my best now to get you through but someday you will wish I did not.

A program is a series of instructions you give to a computer. Modern machines are basically sequential devices that means they do one thing at a time. Code runs line by line, one instruction at a time, from top to bottom.

Start:

a: = 3, b: = 3

These 2 instructions store the value of 3 into a and then b.

for c: = 1 to 4

This instruction is called a for next loop. It starts by initializing some variable with a beginning value (1) and an end value (4). This loop starts with c = 1.

b: = b ∙ c
a: = a + c

These 2 instructions are the body of the loop.

The first one says take what is in b (3) and multiply it by what is in c (1) and store it back into b

The second one says take what is in a (3) and add to it by what is in c (1) and store it back into a

next c

This last statement says add one to c and check whether is greater than 4. If it is not then it will go back to the for c = 1 to 4 statement (underlined ). If it is greater than 4 then the program ends.

What I have done above is called pseudocode. It is mixed english, programming and math.

If you run through the statements that I have given you above and write down the values for c, a, and b you will get the trace table.

THANK YOU THANK YOU VERY MUCH MAN!!

If possible can you please tell me how you got this? in detail please. THANKS!!

Hi mantastrike;

You will never learn how to program a computer if you have some one else do your work for you. This is a very easy problem. Never mind that this method of trace tables is a very poor method. You must do your own work. For the last week and a half all I have heard is "Oh, I am never going to use math in my job, so why do I have to learn it?" If that argument is spurious for mathematics it is doubly spurious for programming. You must make an effort!

Make a trace table to trace the action of the following loop?

a: = 3, b: = 3
for c: = 1 to 4
b: = b ∙ c
a: = a + c
next c
