1. When StructNameisalreadyinuse, StructName_ gives a different name (but you should really come up with a better name). 2. Identifiersinthe C standard library that arenotdefined by the standard shouldn't conflict with user code identifiers. Therefore, C library writers use the _ prefix in...

Now sStudentInformation is new types and whenever in the program we need the above structure variable then no need to write the struct. sStudentInformation aticleworld; Scope of typedef in C Good thing is that the typedef follows the scope rules. It means, it can have block scope, file sc...
in c there is a usage of the typedef as " typedef void number (int, int)". here the example provides the type number for a function returning no value and taking two int arguments. is there is any similar structure in system verilog. i am searching for a straight conversion or some ...
'typedef' is used to create an alias Person for a structure. Instead of writing ‘struct’ Person when declaring variables, you can simply write Person. The code becomes more concise and easier to read. Enum in C 'enum' (enumeration) is a user-defined data type in C that consists of ...

#define GPIOC ((GPIO_TypeDef*) GPIOC_BASE) #define GPIOD ((GPIO_TypeDef*) GPIOD_BASE) In the application code we can program the peripheral special function registers by accessing the structure elements. void LED_Init (void) { RCC->AHB1ENR |= ((1UL << 3) ); /* Enable GPIOD cl...
To create a variable for the above structure, the syntax would be like : struct student stud1; we can make the construct shorter with more meaningful name for types by using typedef. </> Copy typedef struct student { char name[20]; ...
Most C and C++ programmers know that it is bad style to assume that apointer is the same size as an int, although this may often be the case.What is less well known is that pointers of different types may not be thesame size as each other. For example, in 16-bit x86 programming ...
