Microprocessor 8085 Architecture which is shown in the below figure consists of various units and each unit has its respective functionality.Fig: 8085 Microprocessor ArchitectureThese units are listed below-AccumulatorIn Intel 8085microprocessor, accumulator acts an 8-bit register to store 8-bit data to perform arithmetic and logical operation on them. The final result stored in the accumulator. It is also called A register.Arithmetic Logic Unit (ALU)It basically performs 8-bit arithmetic operations like +, -, *, / and to perform logical operations like AND, OR, NOT etc. ALU gets inputs from the accumulator and temporary register on which it performs such operations. After processing ... Read More
This example demonstrate about How to get default Sim Operator id in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken a text view to show device sim operator id.Step 3 − Add the following code to java/MainActivity.xmlpackage com.example.myapplication; import android.Manifest; import android.content.Context; import android.content.pm.PackageManager; import android.os.Build; import android.os.Bundle; import android.support.annotation.NonNull; import android.support.annotation.RequiresApi; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; import android.telephony.TelephonyManager; import android.widget.TextView; import static ...

A 2-D array can be easily passed as a parameter to a function in C. A program that demonstrates this when both the array dimensions are specified globally is given as follows.Example Live Demo#include const int R = 4; const int C = 3; void func(int a[R][C]) { int i, j; for (i = 0; i < R; i++) for (j = 0; j < C; j++) a[i][j] += 5; ; } int main() { int a[R][C]; int i, j; for (i = 0; i < R; i++) for (j = 0; ...

A local array cannot be directly returned from a C++ function as it may not exist in memory after the function call. A way to resolve this is to use a static array in the function. As the lifetime of the static array is the whole program, it can easily be returned from a C++ function without the above problem.A program that demonstrates this is given as follows.Example Live Demo#include using namespace std; int *retArray() { static int arr[10]; for(int i = 0; i
This example demonstrate about How to get default phone Network Specifier in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken a text view to show phone network specifier.Step 3 − Add the following code to java/MainActivity.xmlpackage com.example.myapplication; import android.Manifest; import android.content.Context; import android.content.pm.PackageManager; import android.os.Build; import android.os.Bundle; import android.support.annotation.NonNull; import android.support.annotation.RequiresApi; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; import android.telephony.TelephonyManager; import android.widget.TextView; import static android.Manifest.permission.READ_PHONE_NUMBERS; import ...

An array is a collection of same type of elements at contiguous memory location. The lowest address in the array corresponds to the first element while highest address corresponds to the last element. The array index starts with zero(0) and ends with the size of array minus one(array size - 1).An array can be initialized with variables as well as real numbers. A program that demonstrates this is given as follows.Example Live Demo#include using namespace std; int main() { int a = 5; int b = 3; int arr[4]; arr[0] = a; arr[1] = 8; arr[2] = b; arr[3] = 2; cout
An array can be created using all data types such as int, char, float, double etc. But creating an array by using the void data type is not possible. An error will be displayed if that is done.A program that demonstrates this is given as follows.Example Live Demo#include #include int main() { void arr1[4]; printf("A void array"); return 0; }OutputThe above program returns the following error.error: declaration of ‘arr1’ as array of voids void arr1[4];Now let us understand the above program.An array arr1 of void data type is created in the above program. Since this is ... Read More
This example demonstrate about how to using string writer append in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml In the above code, we have taken editext, button and textview. When user click on button after inserting value in edittext, it will append the data using string writer.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Build; import android.os.Bundle; import android.support.annotation.RequiresApi; import android.support.v7.app.AppCompatActivity; import android.view.View; ...
