If statement in C

If statement

The keyword "if" tells the compiler that what follows is decision control statement.

"If" statement is a conditional branching statement. In conditional branching statement a condition is evaluated,if it is evaluate true a group of statement is executed,or if it is evaluate false then statement are skipped.

What are the instruction set in C Language ?

To understand and for clear idea of question What are the instructions set in C Language ? we need clear idea on what is an instruction and instruction set ?

Instruction Set- An instruction set is a set of instruction in program that execute and compile  by compiler

Instruction is an order that writes in program for specific purpose. Each instruction is a sequence of  0s and 1s that describes a physical operation the computer is to perform (such as \”Add\”) and, depending on the particular instruction type.

What is C language and how it relate with human language?

This is very good question to clear your concept on C that What is C language and how it relate with human language?

      C language is general purpose language developed by Dennis Ritchie at Bell Laboratory in 1972 from a language names B. B was also developed at Bell laboratory.

The first major program written in c was UNIX operating system and for many years, c considered to be inextricably linked with UNIX  , C is an important language independent of UNIX.

What is a constant,variable and keyword in C?

To learn C Language at first we need clear idea on What is a constant,variable and keyword in C?
Constant:

Constant refers to the fixed value that do not change during the execution of program. A constant may be number , character or character string that can be used as a value in a program. To use constant to reprent integer,floating point or charcter value that can not be modified.

       Constant divided into two major categories

Short note on BASIC CONCEPT OF WELDING

In today's world the importance of welding spread over a range,in most of the modern fabrication works welding science has numerous applications in different forms, covering a fairly wide range of such work.

Welding is an alternative method for casting or forging and as a replacement for bolted and riveted

Short note on Transmission Control Protocol/Internet Protocol or TCP/IP

The full name of TCP/IP is Transmission Control Protocol/Internet Protocol. And as name suggest it is responsible for transmission and internet protocol controlling.

TCP/IP is generally described as having four abstraction layers. The top most layers near the top are logically closer to the user application, while same thing true for those layers which near the bottom are logically closer to the physical transmission of the data.

In bellow I discussed on each layer in the TCP/IP networking model starting from the lowest level.

Why we do machining ? What are the basic machining process ?

Machining is very important process in manufacturing. It is used due to following res ion :

• to make surface finishing
• to bring correct shape and size
• to provide threads and whole
• to cut the materials
• to produce seamless tube

What are the difference between Hot Working and cold working?

Please find bellow the defferane between Hot Working and cold working of Manufacturing

SL	HOT WORKING	COLD WORKING
1	Working temperature is above the re crystallization temperature. Therefore, it can be regarded as a simultaneous process of deformation and recovery.	Cold working temperature is below the crystallization temperature.So no appreciable recovery can take place during deformation.

Is investment casting economical than other casting process?

The investment casting is economical than other casting processes due to the following reasons

– Parts of great complexity and intricacy can be cast

– Close dimensional control and good surface finish

What does you mean by casting process? and why we use casting?

Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

Short note on Modularity of design

MODULARITY

It is architecture of product which gives different model of product on different cost. Means customer can buys the product as per his budget and need. It can defined as 

”the property of functional flexibility built into the product by assembling discrete unites which can be joined to or arranged with other parts or modules”.

What does you mean for design for safety and what are the necessary step you take for that?

To provide safety of user while using the product is responsibility of designer. If any accident has occurred while using the product the user may demand the compensation, because it is also mention our constitution. Compensation varies country to country. Many times we have seen about compensation which is announced by railway administration for injured person in trains accident. Because responsibility to safety in train journey is of railway railway administration and this accident occurs due to failure railway system. This is also valid for products or building etc. It means designer will stop to design the product or any other? NO. They will design but with considering design for safety which will reduce the responsibility. Thus we can say that design for safety is tool of reducing the responsibility of designer. Following points should always be kept in mind at the time of designing or manufacturing.

What is a significance of feasibility study and Write 5 differences between Evolution and innovative design ?

A design projects begins with the feasibility study. The purpose of this phase is to achieve a set of useful solutions to the design problem. Sometimes, a design group is assigned to a project for which a design concept has already been fixed. In this case, the first step in the study process is to demonstrate whether there is an original need, which was presumed to be valid, thus indeed have current existence, or strong evidence of latest existence.  The next step is to explore the design problem and to identify its elements such as, parameters, constraints and major design criteria. In the next step, an effort is made to conceive a number of possible solutions.

How does need analysis help to build a good product design? Explain with example

Suppose we have to manufacture a mobile and following are the customer needs, we have got after primary identification of need :- 

• seamless communication 
• sms 
• videos 
• recording videos as well voice

How to define or initialized the stack in program?

It is very good question that How to define or initialized the stack in program? And before

starting the answer i should mention please see my previous post regarding 

Video Tutorial: What is a stack and use of it ?

 Now getting the answer of How to define or initialized the stack in program? The most important thing which we have to remember when we are using stack in program that the stack should be initialized at the high end of the memory map. Now question is why stack should be initialized at the high end of the memory map? See the block diagram first
