 Hi larnkoders in this post you are going to learn  about, How to make pass to new activity with information or simply go to new activity on android studio. This is code is written in Kotlin Programming language.

Let suppose there will be MainActivity.kt and to you want to go to AnotherActivity.kt then\

do this like 

if there is button clicklistener like

button.setOnClickListener{

val intent  = Intent(this,AnotherActivity::class.java)

startActivity(intent)

Calculator Program using Switch statement in C

Q.Basic Calculator Program Using C Language ?

Ans:

#include <stdio.h>
#include <conio.h>
int main() {
int n,num1,num2,total;
printf("Basic Calculator Program Using C\n\a");
printf("Enter the number 1 for Addition \n");
printf("Enter the number 2 for Subtraction \n");
printf("Enter the number 3 for Multiplication \n");
printf("Enter the number 4 for Division \n");
printf("Please Enter the Number:\n");
scanf("%d",&n);
printf("Enter the First Number:\n");
scanf("%d",&num1);
printf("Enter the Second Number:\n");
scanf("%d",&num2);
switch (n){
case 1:
total=num1+num2;
printf("%d is your value",total);
break;
case 2:
total=num1-num2;
printf("%d is your value",total);
break;
case 3:
total=num1*num2;
printf("%d is your value",total);
break;
case 4:
total=num1/num2;
printf("%d is your value",total);
break;
}

return 0;
}
Result :-

Basic Calculator Program Using 
Enter the number 1 for Addition
Enter the number 2 for Subtraction
Enter the number 3 for Multiplication
Enter the number 4 for Division
Please Enter the Number:
1
Enter the First Number:
140

Bubble Sorting Explanation and Simple Program

Q. Write a program to accept 10 numbers from user and sort list using Bubble sorting method.

Ans.

Logic of bubble sorting as follows:

In bubble sorting steps:

1. Start from left hand side

2. Compare first two numbers

3. If first_number > second_number than swap both number position. And if first_number < second_number than these compare next two numbers i.e. second_number and third_number.

4. Step-3 process repeat until there are no more numbers left to compared.

5. Bubble sorting completed.

An example on bubble sort.

To understand logic of Bubble Sorting, lets take random numbers:

6  3  7  1  4  5  2

First iteration

6  3  7  1  4  5  2

3  6  7  1  4  5  2

3  6  7  1  4  5  2

3  6  1  7  4  5  2

3  6  1  4  7  5  2

3  6  1  4  5  7  2

3  6  1  4  5  2  7

Second iteration

3  6  1  4  5  2  7

3  6  1  4  5  2  7

3  1  6  4  5  2  7

3  1  4  6  5  2  7

3  1  4  5  6  2  7

3  1  4  5  2  6  7

Third iteration

3  1  4  5  2  6  7

1  3  4  5  2  6  7

1  3  4  5  2  6  7

1  3  4  5  2  6  7

1  3  4  2  5  6  7

Four iteration

1  3  4  2  5  6  7

1  3  4  2  5  6  7

1  3  4  2  5  6  7

1  3  2  4  5  6  7

Five iteration

1  3  2  4  5  6  7

1  3  2  4  5  6  7

1  2  3  4  5  6  7

Six iteration

1  2  3  4  5  6  7

1  2  3  4  5  6  7

Seven iteration

1  2  3  4  5  6  7

/*A Simple example program to Explain bubble sorting*/

#include<stdio.h>

#include<conio.h>

#define SIZE 7

int main()

{

 int i,j,temp;

 int arr[ SIZE ];

 for(i=0; i<SIZE; i++)

 {

  printf("Enter Number : ");

  scanf("%d",&arr[i]);

 }

 for(i=0; i<SIZE ; i++)

 {

   for(j=0; j<(SIZE-1)-i; j++)

   {

     if( arr[j] < arr[j+1] )

     {

        temp=arr[j];

        arr[j]=arr[j+1];

        arr[j+1]=temp;

     }

   }

   printf("%d\t",arr[j]);

 }
 getch();

 return 0;

}

Output:-

Enter number : 6
Enter number : 3
Enter number : 7
Enter number : 1
Enter number : 4
Enter number : 5
Enter number :  2
1  2  3  4  5  6  7

Program for Selection Sorting

Q. Write a C program to to sort a list of elements using selection sort method.

Ans.

/*program to demonstration of selection method*/

#include<stdio.h>

#include<conio.h>

#define SIZE 10

int main()

{

 int i,j,min,temp;

 int arr[SIZE];

 for(i=0; i<SIZE; i++)

 {

  printf("Enter element : ");

  scanf("%d",&arr[i]);

 }

 for(i=0; i<SIZE; i++)

 {

   min=i;

   for(j=i+1; j<SIZE; j++)

     if(arr[j]<arr[min])

        min=j;

     temp=arr[i];

     arr[i]=arr[min];

     arr[min]=temp;

 }

 printf("After selection sort the elements:\n");

 for(i=0; i<SIZE; i++)

    printf("%d\t",arr[i]);

 getch();

 return 0;

}

Output:-

Enter element : 21

Enter element : 3

Enter element : 45

Enter element : 87

Enter element : 72

Enter element : 14

Enter element : 54

Enter element : 75

Enter element : 44

Enter element : 5

After selection sort the elements :

3  5  14  21  44  45  54  72  75  87
