Answer 1

KrOW, hope you may assit me with this one?

Answer 2

Ok, i am here... Anyway, can you explain better what do you want get? what you mean for "variable diagram"?

Answer 3

LOL, I am still a noob, so bear with me.
the Question states the following:
"Draw variable diagrams for the following program with input values 2 (for variable "first") and 3 (for variable "second").

Figure out how the execution flows in a program like this where the main() calls other functions.

For instance :
1. A ? shows an uninitialized value for variable.
2. The notation 25 -> 5 means that excecution jumps from line 25 to line 5.
3. We use square brackets [] around the name of a variable to show that it is inaccessable while the current function is being executed.

then there is the code that I linked in the description.

Does this make any sence? or am I totally sounding like a retarded noob?

Answer 4

Then you have to trace variable states right? But can you give me your wanted output in this code?

#include <iostream>

int main(){
int first
int second;
cin>>first;
cin>>second;
return 0;
}

Answer 5

Ok, so variable states is the same as a variable diagram? :D
Sorry, I am learning as we speak.
Should you not put in the variables 2 and 3 in the program and then get your output? If that is the case, the output is 6 and 9.

Answer 6

Ruben Oberholzer Dont worry because i dont know this variable diagram (i have not learn coding at school then i lack some concepts)... Anyway do you cannot a example with input and output?

Answer 7

Enter the first number:
2
Enter the second number:
3
The first number is 6now.
The second number is 9now.

Process returned 0 (0x0) execution time : 4.215 s
Press any key to continue.

Answer 8

that is what I got if I run the program with variables 2 and 3

Answer 9

Ruben Oberholzer This is the output of your current code BUT i want know your wanted output for same input...

Answer 10

hmm...I am not sure I understand?

Answer 11

See this code output please and tell me if you want this

Answer 12

You mean if I need these results?

/*

first ?
second ?
19->21
first 2
second ?
21->23
first 2
second 3
23->6
[first]
[second]

*/

Yes, That is what I need, but I need all the diagrams/states for the entire code. :D

Answer 13

I think what they basically want from me is to show exactly what the program does when it executes.

Answer 14

Try to do it, i cannot do it for you... After your try we see
