What programming language is GOOGLE developed in?

C++ and Java are the main languages for production. Search is mostly written in C++, while a lot of the ads infrastructure is written in Java. Python is used as glue, for things like development tools and administration tools. There's a lot of other random languages here and there though - there are projects that use everything from Haskell to perl.

Google also has some of their own languages that exist only within Google, such as sawzall.

How do you convert bcd to ascii hex code?

Multiply by 16.

ANSWER: The answer is bcd 11 = 3 111 = 7 1111 i= F

01111 =E and so foirth

How can a value from the derived class be assigned to a variable in base class?

Remember that derived classes can access the public and protected members of their base class, but none of the private members. If the member variable in the base class is protected (rather than private), then the derived class can assign it directly. However, this is bad style in OOP as it undermines data-hiding. A protected mutator (set accessor) would be a better option.

Which industries is COBOL still commonly used?

Banks & Credit Card, Insurance, Airlines, Federal, State and local Govenments. Over 80 percent of all code being used in the US is written in COBOL.

Program to find factorial of a number using recursion?

#include<conio.h>

#include<stdio.h>

void main()

{

clrscr();

int i=1,fact=1,n;

printf("enter a no.");

scanf("%d"n);

while(i<=n)

{

fact=i*fact;

i++;

}

printf("factorial=%d",fact);

getch();

}

How do you write a c program using functions and array?

Eg:

int main (int argc, char **argv)

{

int i;

printf ("array argv has %d elements:\n", argc);

for (i=0; i

return 0;

}

Indentation is used to make programming code easier to read?

To make the code easier to read for you and other programmers that might view your work.

What is 7-bit code?

7-bit code is an encoding scheme that uses just 7 bits. 7-bit encoding allows positive values in the range 0 through 127. ANSI is a 7-bit encoding scheme. When used on an 8-bit system, bit 7 is always zero (where bit 0 is always the least significant bit). Bit 7 is used by the ASCII extended character set, where the first 127 characters are the same as those defined by the ANSI character set.

7-bit encoding was often used in early tele-printing where bit 7 was not needed. In this way, they could encode eight 7-bit characters into a 56-bit package which could be transmitted and decoded by the 7-bit teleprinter -- the idea being that the fewer bits you transmit, the quicker it will be to send the data across a telephone line.

What is workflow software?

Workflowsoftware (business process management) is an integrated collection of critical software technologies that enables the control and management of business processes.

Workflow software emphasizes business user involvement in the entire business process improvement life cycle, from design through implementation, deployment, monitoring and ongoing optimization. Instead of reducing relience on employees, BPM - Business Process Management software emphasizes the added value of employee activity coordidantion and making their business activities tranparent and auditable

Business Process Management Suites enable business stakeholders to monitor all interactions between human, system and information resources and optimise behavior to get the most out of dynamic market events and improve business performance outcomes.

Workflowsoftware is a model-driven workflow environment that makes the model executable, while keeping the model as the central focus for future process changes. The graphical model is actually metadata that is translated by software into the executed process dynamically.

Workflowsoftware supports the complete business process improvement cycle, from definition to implementation, monitoring and analysis, and through ongoing optimization.

Computer programming vs algorithm?

An algorithm describes the finite procedural steps required to solve a problem. Algorithms are typically written so humans can easily understand those steps. Computer programming is the means by which a computational problem is converted into executable code. This often entails the development of algorithms which must be converted from the human-readable form into native machine code, typically using high-level programming languages to produce the abstract, human-readable source code, and compilers or interpreters to produce the machine-readable code.

Is Assembly-language programs are written using binary codes?

Assembly language allows the developer to have almost total control over what the sequence of instructions will be when a program executes. A compiler tries to translate a high level language such as C++ into a series of instructions, but a good assembly language programmer may be able to optimize the sequence when a compiler cannot.

Primarily assembly language is used for speed and optimal machine code.

What is the furlough program?

a layoff, especially a temporary one, from a place of employment.

What are the differences between QBasic and FORTRAN Programming language?

PROGRAMMING is a process of developing computer program.While FOTRAN means formula translation which translate math formula into code in high level programming language.

What is the definition of circular queue?

A queue is simply a FIFO i.e first in first out. In queue we've front and rear. Front is the initial or first location of the queue whereas rear indicates the last entry location in the queue. In the circular queue the location of front and rear will be the same IF the total space of the circular queue is utilized. Each element has its position no. for insertion , if we set the 5th element as the front element then after every insertion the ptr indicates the 5th element as front. in deletion, the fifth element is deleted every time it is the rear position. after deletion of an element the queue rotates and every time the rear indicates the 5th element of the circular queue. and every time the 5th location element is deleted.

What are the application of mathematics in international relations?

In business mathematics are applied in various instances. To start, Accounting, which provides basic needs of profit, payroll, and logistics. Secondly, engineering and statistics. They aid in providing company with a dissected approach to information.

Can an for loop be terminated with a semicolon in c language?

Sure.

for (i=0; i;

or

i=0; do printf ("%d %s\n", i, argv[i]); while (i++;

What two programming language deficiencies were discovered as a result of the research in software development in the 1970s?

There were far more than 2 deficiencies found during the 1970s so its hard to identify which two you are specifically referring to. Every language was and still is deficient in some way, otherwise there would be no need to evolve the existing languages never mind invent new languages and new development techniques.

What is difference between uni-programming and multiprogramming?

multiprogramming or multitasking means more than one program can execute at the same time. It is the allocation of a computer system and its resources to more than one application at the same time. However in uni-programming you can have only one program running at any point in time.

What are the two types of programming language?

2 types of java programs are application and applet application program is the one which run on ur computer under the O.S of ur computer. applet is an application designed to be transmitted over the Internet and executed java compatible web browser.

What is the difference between a constructor and its corresponding overloaded assignment operator?

The copy constructor is used to initialize a new instance from an old

instance, and is called when passing variables by value into functions

or as return values out of functions.

The assignment operator is used to change an existing instance to have

the same values as the rvalue, which means that the instance has to be

destroyed and re-initialized if it has internal dynamic memory.

What is memory leak?

When a piece of software running for an extended time uses more and more memory. The software is not releasing its resources correctly! And so the machine cannot recoup memory.

It is possible that eventually the machine will crash, or the offending software will need restarted.

What is the difference between imperative and non-imperative programming languages?

Imperative languages focus on how the program should follow it's tasks, while non-imperative languages, functional or logical, tell the program what it needs to do, as opposed on how to do it.
Imperative programming is programming which changes the computer's state and focuses on how a program is to perform. Non-imperative languages are predominantly declarative languages, where the programmer states what is to be performed without specifying how to achieve it.
