Why is c considered as a high level language and a low level language?
Satt Crypt
- Oct 16th, 2013
Here the 1st answer is 22 and second is 15 because in case of ++a + ++a + ++a then 1st increment then addition let temp=(++a + ++a)==7+7=14 and then ++a =14+8=22
and for 2nd case 5+5+5=15.jbode

C is a high-level language because it abstracts away a large part of the underlying machine; instead of dealing with registers and opcodes, youre dealing with objects and expressions. Streams are abs...

Create a struct and set two values inside and return the struct variable. You have to allocate space for the char * in your program. Use pointers as your function parameters. Then use them to return multiple value

What is the benefit of using #define to declare a constant?
Using the #define method of declaring a constant enables you to declare a constant in one place and use it throughout your program. This helps make your programs more maintainable, because you need to maintain only the #define statement and not several instances of individual constants throughout your program. For instance, if your program used the value of pi (approximately 3.14159) several...

I see examples such as #define PI 3.1415, which show _how_ you can use a define to declare a constant, but don't exactly explain _why_ you'd want to do this, rather than, say, const double PI ...

When you define constant variable there is possiblity that it's value may get changed in the program accidently by use of say pointer, but if you define constant by #define it's value can't be changed. This is also one of the benifit of using #define.

How can I convert a number to a string?
The standard C library provides several functions for converting numbers of all formats (integers, longs, floats, and so on) to strings and vice versa The following functions can be used to convert integers to strings: Function Name Purpose itoa() Converts an integer value to a string. ltoa() Converts a long integer value to a string. ultoa() Converts an unsigned long integer value to a string....

Which expression always return true? Which always return false?
expression if (a=0) always return false expression if (a=1) always return true

Here the question exactly means the statement which will always irrespective of any condition and the statement which will never execute, so here if we useif (1) it will always execute or will return true andthe statement if (0) will never execute or will always return false.

Ya answer is FREE() bczmalloc() is used to allocate single block of memorycalloc() is used to allocate multible blocks of memoryrealloc() is used to reallocate the allocated memorybut free()is used to deallocate the memory
Nishi Rathore

Free() is odd because rest functions are used to allocate memory and free is used to deallocate the memory

What is the draw back in using friend function in c++
kbjarnason
- Jul 2nd, 2010
The basic problem is that it blows away your encapsulation. Friend functions see right through "protected" and "private" and can see blinkin' everything.Or, in other words, "your friends get to play with your private parts." :)

the memcpy function will copy n bytes from the object pointed by strB into strA. If the copying takes places between objects that overlap, the behaviour will be undefined. If these to char pointer is assigned an address which don't overflow, this would work.Thanks,mani

Answer is A. This is how I reason it outmBit contains the inverse of bit. All the 1's in bit become 0 and all the 0's in bit become 1. 512 is positive so the result of this inverse has to be a -ve num...
