In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. An inverter circuit outputs a voltage representing the opposite logic-level to its input.

There is no automatic conversion from array of primitive type to array of their boxed reference types or vise versa. You have to iterate for each data. Converting List<Long> to long output = new long; int index = 0; for(Long val : input) { indexess = val; index++; } Converting long input = getSomeLongs(); // Assume some [...]

In C and C++, enum types can be used to set up collections of named integer constants. Consider a set of all days. #define Sunday 0 #define Monday 1 #define Tuesday 2 #define Wednesday 3 #define Thursday 4 #define Friday 5 #define Saturday 6 The above lines can be replaced by: enum AllDays{Sunday, Monday, Tuesday, [...]

There is no bool data type in C. In C99 standerd version, the boolean variable has been added as _Bool. Additionally, a new header stdbool.h has been added for compatibility reasons. This header allows programmers to use boolean types in the same way, as in C++ language. To use bool in C, we can use [...]

void main()
{
int const * p=5;
printf(“%d”,++(*p));
}

1. calloc allocates a block of memory for an array of elements of a certain size. By default the block is initialized to 0. The total number of memory allocated will be (number_of_elements * size). malloc takes in only a single argument which is the memory required in bytes. malloc allocated bytes of memory and not blocks of memory [...]

A function pointer is a variable which is used to hold the starting address of a functions and the same can be used to invoke a function. It is also possible to pass address of different functions at different times thus making the function more flexible and abstract. So the function pointers can be used [...]
