Read MoreDifference between while(1) and while(0) in C/C++
Here we will see what are the differences between while(1) and while(0) in C or C++. The while is a loop of C or C++. Using this loop we can check one condition, and the statements inside the loop will be executed while the condition is true.The while(1) or while(any non-zero value) is used for infinite loop. There is no condition for while. As 1 or any non-zero value is present, then the condition is always true. So what are present inside the loop that will be executed forever. To come out from this infinite loop, we have to use ...
Read More8085 Program to perform sorting using selection sort
Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to sort a sequence of numbers using selection sort.Problem Statement:Write 8085 Assembly language program to sort a given sequence using selection sort in ascending order. The numbers are stored at 8001H onwards. 8000H is holding the block size.Discussion:In the selection sorting technique, we will choose the minimum or the maximum term from a set of numbers. In this case we are considering the sorting in ascending order, so we are choosing the minimum number. By taking the minimum number, we are swapping it ...
