Data types specify how we enter data into our programs and what type of data we enter. C language has some predefined set of data types to handle various kinds of data that we can use in our program. These data types have different storage capacities. C language supports 2 different types of data types: […]

Volatile is a qualifier that is applied to a variable when it is declared. It tells the compiler that the value of the variable may change any time. The implications of this are quite serious. It is required when you experience the following in C/C++ code: Syntax: For declaration of volatile variable, make use of

At present cars and other private vehicles are used daily by many peoples. The biggest problem regarding the increased use of private transport is the increasing number of fatalities that occur due to accidents on the roads; the expense and related dangers have been recognized as a serious problem being confronted by modern society. VANET

The variable-length argument is a feature that allows a function to receive any number of arguments. These are situations where we want a function to handle the variable number of arguments according to requirements. Variable number of arguments are represented by three dotes ( . . . ) int Fun(int num, . . .) {

Advanced driver assistance systems require higher accuracy at similar, or in some cases larger, air gap distances between the sensor and the sensed target. Giant magneto-resistance (GMR) is a strong candidate to meet these enhanced requirements. Front-biased magnetic encoder rings are the most common target type in today’s light vehicle applications and the most common

A structure is a user defined data types, it is used to group a different type into a single type. It allocates contiguous memory locations, we can access the structure elements through structure variable along with dot operator or arrow operator depends upon the structure variable, if structure variable is pointer will use arrow operator

Like embedded hardware, embedded software architecture is highly flexible. Simple embedded software (such as electronic toys, calculators, and so on) may be only a few thousand lines of code and perform simple input and output functions. On the other hand, complex embedded systems (such as smartphones, robots, and so on) need more complex software architecture,

Sensors:   The intrinsic part of the embedded system is the sensors. Right from simple tv remote to security systems installed at home. They are also becoming important for weather stations to forecast weather parameters(temperature, wind speed, wind direction, solar radiation, and many more) and in IoT(to gather data, sharing data etc). Definition and Working of

There are two ways to pass arguments to a function — Pass by Value and Pass by Address. The major difference between Pass by Value and Pass by Address is in the pass by value copy of actual arguments is passed to respective formal arguments. While, in the call by reference, the location (address) of

Macros are preprocessed, meaning that all the macros would be executed before the compilation stage. However, functions are not preprocessed but compiled. Example of Macro: #include<stdio.h> #define  A 10 int main() {      printf(“%d”,A);      return 0; }  OUTPUT=10; Example of Function: #include<stdio.h> int A() {     return 10; } int main() {     printf(“%d”, A());     return 0; }
