Display a pseudocode for a calculator programme?

It displays the power to which '10' would have to be raised in order to get the number you entered. That's the definition of the 'logarithm' or 'log' of a number. Examples: Enter 100. Hit 'log x'....

import java.io.*;public class calculator{ public static void main(String[] args) throws Exception{ int x, y; BufferedReader b = new BufferedReader(new InputStreamReader(System.in)) ; ...

The data is held in a register. There may be many registers holding data. When new data is entered the old data in the register(s) is overwritten.

include<stdio.h> int main (void) { printf("hallo world\n"); return 0; }

Enter 1000 - 710 = Or 140 + 150 = Or 58 * 5 = or many many more possibilities.
