8085 program to find the factorial of a number
In this program we will see how to find the factorial of a number.Problem StatementWrite 8085 Assembly language program to find the factorial of an 8-bit number.DiscussionIn 8085, there is no direct instruction to perform multiplication. We need to perform repetitive addition to get the result of the multiplication. In each step we are decreasing the value of B and multiply with the previous value of B. We are repeating these steps until B reaches 1. and B – 1 to 0. Thus the factorial is generated.InputAddressData800005Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80 LXI H, 8000HLoad the numberF00346 MOV B, MTake number from memory ...
Read MoreHow to fasten MySQL inserts?
You can speed the MySQL insert when you are inserting multiple records at the same time with the help of the following syntaxSTART TRANSACTION insert into insertDemo(yourColumnName1, yourColumnName2, ...N) values(yourValue1, yourValue2, ....N), (yourValue1, yourValue2, ....N), .......N commitLet us first create a demo tablemysql> create table insertDemo -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20), -> StudentAge int -> ); Query OK, 0 rows affected (0.72 sec)Insert multiple records at the same time. The query is as follows −mysql> START TRANSACTION; Query OK, 0 rows affected (0.00 sec) mysql> insert into ...
Read MoreC++ Program to Perform Searching Using Self-Organizing Lists
Self-Organizing list basically updates the list of given range of items on the basis of last searched item. In this method, the sequential searching approach is used. This algorithm shifts the more important data to the beginning of the list. The time complexity of this search technique is O(n).AlgorithmBegin Function FibonacciSearch(). Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with the left sub-array. If it is more ...
Read More8085 program to find minimum value of digit in the 8 bit number
In this program we will see how to find the minimum digit from a two-digit number.Problem StatementWrite 8085 Assembly language program to find the minimum digit from a two-digit number. The number is stored at location 8000H, store the result at 8050H.DiscussionHere we are performing this task by using masking operation. Each digit takes one nibbles. We are masking the upper nibble by ANDing with 0FH (0000 1111). Store the lower nibble into another register. After that, we are taking the upper nibble. To get it, we are shifting the number to the right four times to convert lower nibble ...
Read MoreHow do I stop a MySQL decimal field from being rounded?
You can stop rounding decimal field with the help of DECIMAL() function. Here is the demo of a rounded decimal field. For our example, let us first create a demo tablemysql> create table stopRoundingDemo -> ( -> Amount DECIMAL(7) -> ); Query OK, 0 rows affected (0.67 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into stopRoundingDemo values(7836.783); Query OK, 1 row affected, 1 warning (0.43 sec) mysql> insert into stopRoundingDemo values(1737.67); Query OK, 1 row affected, 1 warning (0.23 sec) mysql> insert into stopRoundingDemo values(110.50); Query OK, 1 ...
Read More8085 Program to simulate decimal up counter
Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to simulate the decimal up counter.Problem Statement:Write 8085 Assembly language program to simulate decimal up counter.Discussion:In this section we are simulating the decimal up counter. Here the counter will count 100 decimal numbers from 0 to 99. All values will be updated in each 0.5 seconds. For decimal count we are using the DAA instruction.Note: Here for simplicity we are storing the numbers into memory. To simulate it like a counter we can use 7-segment display to show the numbersInput:Here we are not ...
Read MoreC++ Program to Search Sorted Sequence Using Divide and Conquer with the Aid of Fibonacci Numbers
In this C++ program we implement a Divide and Conquer approach using Fibonacci numbers. Using Fibonacci numbers, we calculate mid of data array to search the data item. The time complexity of this approach is O(log(n)).AlgorithmBegin Assign the data to the array in a sorted manner. Take input of the element to be searched. Call FibonacciSearch() function. Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with ...
