What is an opportunity problem and directive in system analysis?
1) A problem a. Problems are undesirable situations that prevent an organization from achieving its goals. Problems can be current or anticipated. b. Example: users of an information system may be having trouble logging into a system or getting information in a timely manner because the system has reached its capacity. In response, the company could initiate a project to enhance the current system by adding more access lines or upgrading the hardware with a faster processor, more memory, or storage space. 2) An opportunity a. Opportunities are chances to improve the organization. b. Example: A company might believe it could enhance sales by selling products directly to customers over the Internet. The company could initiate a project to provide direct sales of products through the website. 3) A directive a. Directives are new requirements imposed by management, government, or some external influence. b. Example: An important customer might require that all of its vendors use a certain form of electronic data interchange (EDI) in order to do business with them. Management would then initiate a project to implement this form of EDI to maintain business with that customer.
What kind of job can you get with a BSIT degree?
You mean a BS in Information Technology? (It's usually not very artistic ;) My BS degree in Computer Information Systems included a lot of IT stuff. IT is very generalized. Most IT people I know wear many hats: setting up new computers; installing software; occasionally, some programming; administrative ("admin") tasks, like assigning and maintaining user permissions; coordinating system functions, such as EDI communications with the business systems. It can be very stressful, but, if you like holding a company's heart in your hand, it can be very rewarding.
Assembly language for sudoku puzzle?
TITLE sudoku ; Program Description: ; This program is a sudoku game generator and sudoku puzzle solver. ; According to the choices on the program you will chose if you want to produce a new puzzle, or to make the computer solve a puzzle given by you. ; When you chose to make the computer solve the puzzle for you, you will have to enter the number of values that the puzzle contains, and then, you will enter the non-zero ; values by firsly entering their coordinates (i and j). Attention! Enter the coordinate considering the puzzle a 2-dimensional array, which starts from index 0. ; so give the i and j values inside the range : [0, 8] .386 .model flat ; there are the prototypes of the procedures used in this program. They will be explained by adding comments in the beggining of each procedure inside dhe program code. Also there will be comments inside the procedures. public _solver public _generate public _hideCells public check_initial_puzzle public solve public check public checkColumn public checkColumn public getValue public checkGroup public check_coordinate public backtracking public inc_current_value public make0_current_value grid EQU [ebp+8] used_i EQU [ebp+12] used_j EQU [ebp+16] n EQU [ebp + 20] seed EQU [ebp + 24] .data value DWORD ? counter DWORD 0 ; group_i and group_j are the initial coordinates for a group. There are totally 9 groups. for example the first group's coordinate is 0, 0. The group found right to this has the coordinate 0, 3. and so on. group_i DWORD ? group_j DWORD ? ; current_i and current_j are very used in this program code, because almost all procedures need these two variables which are global. ; they express the current i and current j coordinates being currently used. So for example, when e procedure modifies them , there may be another procedure which takes the data stored in these 2 variables and manipulates it. current_i DWORD 0 current_j DWORD 0 ; this is a boolean which is 1 in case that the cell can be filled ;and it is 0 when the cell cannot be filled because it is the constant value comming in the sudoku puzzle. not_constant DWORD ? ; index is used to move inside an array index DWORD 0 ; this is a string containin the 1-9 values which will be put randomly on an empty grid, after that the solve procedure is called in order to solve this grid ; and as a result a new solved random puzzle will be generated one_to_nine DWORD 1,2,3,4,5,6,7,8,9 ; the seed is taken from the main.cpp and it is stored in seed_value. after that the program changes it addind values of the adresses of the esi where currently ; the esi points. It is done in order to generate random values and in each program start these random values will be different, because seed takes the value from the function GetTickCount() seed_value DWORD 0 no_solution DWORD 0 .code ; The solve procedure is the place where other procedures are called in order to make this program work correctly. The algorithm to solve the sudoku puzzle consists on ; the bactracking rules. So it is something like brute-force but it has a better efficciency because when trying the new value it firstly checks the column, row and group. ; All the entered value's coordinates are stored in the used_i and used_j, which using the same index respectively, they express a value found in the grid (which is our puzzle) ; For example, let's assume that the value X has the coordinate i=4, j=6 and using the same index the coordinates are stored in used_i and used_j. for example used_i[index] and used_j[index] solve PROC NEAR mov esi, grid ;esi points to the start of the grid adress mov current_i, 0 mov current_j, 0 loop_i: loop_j: cmp current_i, 8 jg out_i cmp current_j, 8 jg out_j call check_coordinate cmp not_constant, 0 je next_cell next_value: cmp no_solution, 1 je there_is_no_solution call inc_current_value call getValue cmp value, 9 jg backtrack call check cmp eax, 0 jne next_value jmp next_cell ;call inc_current_value backtrack: call make0_current_value call backtracking jmp next_value next_cell: inc current_j jmp loop_j out_j: inc current_i mov current_j, 0 jmp loop_i there_is_no_solution: mov eax, 0 jmp end_solving out_i: mov eax, 1 end_solving: ret solve ENDP _solver PROC NEAR push ebp mov ebp, esp push esi call check_initial_puzzle cmp no_solution, 1 je wrong_puzzle call solve jmp ok wrong_puzzle: mov eax, 0 ok: pop esi pop ebp ret _solver ENDP ; here is the procedure which will generate current_i and current_j randomly.

How do you make binary to decimal converter in G W BASIC?
First of all we will talk about how binary number are converted back into decimal representation and later we will have program.Here is the formula of this transformation:Binary number: a3a2a1a0Decimal number a x 23 + a x 22 + a x 21 + a x 20Example:Binary: 1101Decimal: 1 x 23 + 1 x 22 + 0 x 21 + 1 x 20 = 8 + 4 + 0 + 1 = 13And here we have our program:#include #include #include int main() {char str[100];int ind;int sum = 0;printf("Please enter binary number: ");scanf("%s", str);for(ind = 0; ind < strlen(str); ind++) {sum += (str[ind] - 0x30) * pow(2, strlen(str) - ind - 1);}printf("Number in decimal would be %d\n", sum);return 0;}Testing:Please enter binary number: 1101Number in decimal would be 13Please enter binary number: 10000001Number in decimal would be 129Please enter binary number: 11111111Number in decimal would be 255Please enter binary number: 0Number in decimal would be 0
