W.A.P to read array of integers and print it in reverse order.

Practical Set-4
W.A.P to read array of integers and print it in reverse order.

#include<stdio.h>
#include<conio.h>

void main()
{
   int n, i, j, a[100], b[100];

   printf("Enter the number of elements in array:\n");
   scanf("%d", &n);

   printf("Enter the array elements:\n");

   for (i = 0; i < n ; i++)
      scanf("%d", &a[i]);

   for (i = n - 1, j = 0; i >= 0; i--, j++)
      b[j] = a[i];

   for (i = 0; i < n; i++)
      a[i] = b[i];

   printf("Reverse array is:\n");

   for (i = 0; i < n; i++)
      printf("%d\n", a[i]);

   getch();
}

OUTPUT:
Enter the number of elements in array: 3
Enter the array elements:
3
1
2
Reverse array is:
2
1
3

Write a C Program to given no in ascending order.

Practical Set - 4
5. Write a program to given no in ascending order.

#include<stdio.h>
#include<conio.h>

void main()
{
    int i, j, temp, n, number[30];
    clrscr();
    printf("\n How Many Numbers: \n");
    scanf("%d", &n);
    printf("Enter the numbers: \n");
    for (i = 0; i < n; ++i)
        scanf("%d", &number[i]);
    for (i = 0; i < n; ++i)
    {
        for (j = i + 1; j < n; ++j)
        {
            if (number[i] > number[j])
            {
                temp =  number[i];
                number[i] = number[j];
                number[j] = temp;
            }
        }
    }
    printf("Ascending order: \n");
    for (i = 0; i < n; ++i)
printf("%d\n", number[i]);

    getch();

}
OUTPUT:
How Many Numbers: 3
Enter the numbers: 
30
20
10
Ascending order:
10
20
30

Write a C Program to Add, subtract and multiply two nos. using switch statement.

PRACTICAL-SET-4

3.  Add, subtract and multiply two nos. using switch statement.

#include<stdio.h>
#include<stdio.h>

void main()
{
int num1,num2, choice;
clrscr();

printf("Enter the value of number1 : ");
scanf("%d",&num1);

printf("Enter the value of number2 : ");
scanf("%d",&num2);


printf("\n 1. Addition, ");
printf("\n 2. Substraction,");
printf("\n 3. Multiplication,  ");
printf("\n 4. Division.");

printf("\n Enter Your Choice:");
scanf("%d",&choice);

switch(choice)
{
case 1:
printf("%d + %d = %d",num1, num2, num1+num2);
break;

case 2:
printf("%d - %d = %d",num1, num2, num1-num2);
break;

case 3:
printf("%d * %d = %d",num1, num2, num1*num2);
break;
case 4:
printf("%d / %d = %d",num1, num2, num1/num2);
break;

default:
printf("Please enter the correct choise!!");
}
getch();

}

OUTPUT:
Enter the value of number1 : 10
Enter the value of number2 : 10
 1. Addition,
 2. Substraction,
 3. Multiplication,
 4. Division.

Enter Your Choice:1
10 + 10 = 20

Write a c program to reverse the digit.

PRACTICAL-SET-4 
2.  Write a program to reverse the digit.


#include<stdio.h>
#include<conio.h>

void main()
{
    int num,r,reverse=0;
    clrscr();

    printf("Enter the number: ");
    scanf("%d",&num);

    while(num)
{
         r=num%10;
         reverse=reverse*10+r;
         num=num/10;
    }

    printf("Reverse of a given number is = %d",reverse);
getch();
}

OUTPUT:
Enter the number:  1234
Reverse of a given number is = 4321
