Go to phpmyadmin then edit your ID table to "auto increment" and click the check box and make it "primary". No need to code it

Happy easter to you all.

I have beeen cracking my brain for hours to solve this logic in php but with no succes in site and tried googling it was not clear. Here it goes.

I have this serial values 1,2,3,4,5,6,7,8,9,10 as id in my database. Using SELECT statement to call the values was ok. But here is my problem, I want 1 to be added to 1 from the database, 1 subtracted from 2 from the database, 1 added to 3 from the database, 1 subtracted from 4 from the database etc. Each operation should be added to an array which will be called later using for loop.

I thought of using array, if then else, i just cant rap my fingers around it, can someone help

ijeezlux:
can you please name some of the complex data types that may vary with version

ijeezlux:
hello gurus i have a little issue i need you guys to help me clarify ...... it goes like this.. when writing or reading data into qdatastream object, is it a must that i set the version of the Qt am using e.g (Qdatastream stream; stream.setVersion(...); ). i also have another question. i always see a certain quint32 magic_number variable when doing data serialization with Qdatastream object. but i dont really know whats the main function of this magic_number variable. is it a must to use it? it making me confused...... thanks in advance for ur answer

Consider the following pseudocode.

program main ()
begin
integer p, q, r, s
p = 6
q = 7
r = 8
s = fxn (p, q, r)
print s, p, q, r
end

integer fxn (integer a, integer b, integer c)
begin
if (a > 6) then b = 25
c = a + b
return b + c
end

If fxn uses call-by-reference, what values would be printed as a result of executing the pseudocode?

Sorry that's a typo. My brain meant to type q++ while my hand typed k++. My apologies

1st comparison, q = 0 ----- 0%3 =====> 0, output = 0 + 1 = 1-----------1
2nd                 q = 1------1%3=====>  0. output = 1 + 1 = 2------------2
3rd                  q = 2------2%3=====> 0, output = 2 + 1----------------3
4th                  q = 3------3%3=====> 0, output =  3 + 1---------------4
5th                  q = 4------4%3=====> 1, output =  4 + q = 4 + 4-------8

Here we go guys

Consider the following function
int t ()
{
int q, output;
output = 0;
for ( q = 0; q < 5; k++ )
{
if ( ( q % 3 ) == 1 )
output = output + q;
else
output = output + 1;
}
return output;
}
What value is returned as a result of the call t () ?

Math Tutor

Purpose
This assignment is designed to help students in using C++ to perform basic calculations. Students will also gain experience with generating randon numbers.

Problem Statement
Write a program that can be used as a math tutor for a young student. The program should display two random numbers between 1 and 9 to be added, subtracted, multimplied, and divided, such as 3 * 9 =

After the student has entered an answer and pressed the [Enter] key, the program should display the correct answer so the student can see if his or her answer is correct.

Sample Output
3 + 9 = 12
That's Correct
3 - 9 = 6
Sorry, That's not correct, the correct answer is -6
3 X 9 = 27
That's Correct
3 / 9 = 0.333
Sorry, That's not correct, the correct answer is 0.

My Ogas I need some ideas on how to write the syntax

<?php
$fam = array("Steve", "John", "Madu", "Cynthia" );

?>

That is all I got

<?php
$arrayOfNames = array("Emmanuel", "Osas Omon", "Victor ekon", "Abu aliyu" ); // Creates an array of names
array_push($arrayOfNames, "grace owoh" ); // adds "grace owoh" to the end of the array
sort($arrayOfNames); // sort the array
$randomName = $arrayOfNames[rand(0, count($arrayOfNames)-1)]; // rand takes lower and upper limits
echo strtoupper($randomName); // output in uppercase

So I have been using codecademy lately to study programming. And things have been going fine but now I am stucked.

TO THE GEEKS HERE:

Sorry for asking this, but is it possible to learn programming ordinarily by online turorials and e-books alone?

I mean without an instructor.

nembudziya:
yeah, i guess so...... I am afraid i am going to spend the better part of my time trying to grasp c++, and by the time i reach......yrs i def must an expert. I tried reading the deitel and harvey text book, but man, i could not understand the jargon, but at least it got me thinking otherwise, anyways thanks bros.

nembudziya:
hmmmmmm..........i am astounded. Whats a console, though. Guy, i think you also have to help me on friendship and inheritance cos its one area i'd to master, plus pointers, wow, especially the *this pointer. Hope to hear from you concerning this one matter. Thanks in advance.
