In this program we will see how to check a number is prime or not using 8085.Problem StatementWrite 8085 Assembly language program to check whether a given number is prime or not.DiscussionHere the approach is little bit different. We are actually counting the number of unique factors. For prime numbers the factors are only two. The 1 and the number itself. So if the result is 02H, then it is prime, otherwise not a prime number. As there is no division operation, we have to perform division by subtracting repeatedly.InputAddressDataF10007 AddressDataF100FF AddressDataF1002F Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, F1 LXI H, F100Point to F100 to take ...

There are a couple of ways to empty an array in javascript.Let's suppose take an arrayvar array1 = [1, 2, 3, 4, 5, 6, 7];Method 1var array1 = [];The code above will set the number array to a new empty array. This is recommended when you don't have any references to the original array 'array1'. You should be careful with this way of empty the array, because if you have referenced this array from another variable, then the original reference array will remain unchanged.Example var array1 = [1, 2, 3, 4, 5, 6, 7]; // ...

The circle inscribed in a regular hexagon has 6 points touching the six sides of the regular hexagon.To find the area of inscribed circle we need to find the radius first. For the regular hexagon the radius is found using the formula, a(√3)/2.Now area of the circle inscribed is 3πa*a/4SampleSide of hexagon − 4Area = 37.68Example Code Live Demo#include int main(void) { int a = 14; float pie = 3.14; float area = (float)(3*a*a*pie/4); printf("The area of circle inscribed in the hexagon of side %d is %f", a, area); return 0; }OutputThe area of circle ...
