So only if clause will execute and it will print: David Beckham on console. But it is bad programming practice to write constant as a condition in if clause. Program control cannot reach at else part.
So compiler will show another warning message: Unreachable code 9. What is meaning of following declaration?
B ptr is array of pointer to function. C ptr is pointer to such function which return type is array. D ptr is pointer to array of function. What will be output of following c code?
So it will search the definition of variable x. AS we know do-while executes at least one time even that condition is false. So program control will reach at printf statement at it will print octal number 10 which is equal to decimal number 8.
It is cause of compilation error. Hence compiler will show an error message: Misplaced else Explanation: As we know in c zero represents false and any non-zero number represents true.
So in the above code: So only if clause will execute and it will print: David Beckham on console.
But it is bad programming practice to write constant as a condition in if clause. Hence compiler will show a warning message: Condition is always true.
Since condition is always true, so else clause will never execute. Program control cannot reach at else part. So compiler will show another warning message: Unreachable code 9.
What is meaning of following declaration?
B ptr is array of pointer to function. C ptr is pointer to such function which return type is array. D ptr is pointer to array of function. E None of these Answer: B Explanation: Here ptr is array not pointer.
Copyright ritesh kumar: Case expression cannot be constant variable. A Kevin Spacey Copyright ritesh kumar: Case expression can be enum constant.
What will be output of following c code? Here variable x is extern type. So it will search the definition of variable x. AS we know do-while executes at least one time even that condition is false. So program control will reach at printf statement at it will print octal number 10 which is equal to decimal number 8. In inner do- while loop while condition is!
Hence program control will come out of the inner do-while loop.
In outer do-while loop while condition is 0. That is again false. So program control will also come out of the outer dowhile loop. A stack is one form of a data structure.
At any particular instance, only the top of the stack is accessible, which means that in order to retrieve data that is stored inside the stack, those on the upper part should be extracted first. When writing programs that will store and retrieve data in a file, it is possible to designate that file into different forms. A sequential access file is such that data are saved in sequential order: one data is placed into the file after another. To access a particular data within the sequential access file, data has to be read one data at a time, until the right one is reached.
This refers to the process wherein a variable is assigned an initial value before it is used in the program. Without initialization, a variable would have an unknown value, which can lead to unpredictable outputs when used in computations or other operations. Spaghetti programming refers to codes that tend to get tangled and overlapped throughout the program.
This unstructured approach to coding is usually attributed to lack of experience on the part of the programmer.

Spaghetti programing makes a program complex and analyzing the codes difficult, and so must be avoided as much as possible. It is made up of the commands and other English-like keywords that are supposed to instruct the computer what to do. However, computers would not be able to understand source codes.
Therefore, source codes are compiled using a compiler. The resulting outputs are object codes, which are in a format that can be understood by the computer processor. In C programming, source codes are saved with the file extension.

C, while object codes are saved with the file extension. This is a common problem for beginners because quotes are normally part of a printf statement. It is referred to as a terminating null character, and is used primarily to show the end of a string value. It is used to assign a value to a given variable.
The modulus operator outputs the remainder of a division.By Abhimanyu Chhabra. On the other hand, C can directly access memory structures similar to assembly language routines. What will be output if you will execute following c code?
C advanced interview questions and answers 1 What will be output if you will compile and execute the following c code? Constants are given values at one time only, placed at the beginning of a program.
C Programming Questions and Answers
Question 03 Why is indentation important? These 2 functions basically perform the same action, which is to get the absolute value of the given value.
Pointers contain the address of a variable, which in turn may contain a value or even an address to another memory.
