Here we will see how to divide two 16 bit numbers using 8085.Problem StatementWrite 8085 Assembly language program to divide two 16-bit numbers.Discussion8085 has no division operation. To perform division, we have to use repetitive subtraction. To perform 16-bit division, we have to do the same but for the register pairs. As the register pairs are used to hold 16-bit data.The Divisor is stored at location FC00 and FC01, the dividend is stored at FC02 and FC03. After division, the quotient will be stored at FC04 and FC05, and the remainder will be stored at FC06 and FC07.InputAddressDataFC008AFC015CFC025AFC031D Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00001, ...

In this program we will see how to find a number who appears only once in an array of elements.Problem StatementWrite 8085 Assembly language program to find a number who appears only once in an array of elements. The size of the array is stored at location F100; the numbers are stored from memory location F101 onwards. The result will be stored at F150.DiscussionThe logic behind this problem is simple. Though it may find some wrong results in some cases. It can find the number if there is only one number which is appeared once, and rest of the numbers ... Read More
The shadowOffsetY property of the HTML canvas is used to set the vertical distance of the shadow from the shape. The element allows you to draw graphics on a web page using JavaScript. Every canvas has two elements that describes the height and width of the canvas i.e. height and width respectively.Following is the syntax −context.shadowOffsetY=num;Here, num represents the vertical distance in pixels. Let us now see an example to implement the shadowOffsetY property of canvas −Example Live Demo var c = document.getElementById("newCanvas"); var ctx = c.getContext("2d"); ctx.shadowBlur = 30; ctx.shadowOffsetX = ...
