in c programing Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 The program must define and call the following two functions. Define a function named IntToReverseBinary that takes an int named integerValue as the first parameter and assigns the second parameter, binaryValue, with a string of 1's and 0's representing the integerValue in binary (in reverse order). Define a function named StringReverse that takes an input string as the first parameter and assigns the second parameter, reversedString, with the reverse of inputString. void IntToReverseBinary(int integerValue, char binaryValue[])void StringReverse(char…
I am attempting to remake a diagram that shows the process of my color mixer program in C++. I have learned a new method of calling functions in a certain order to make the code nicer. I am still having some trouble learning how to make a flow-chart that uses proper shapes and symbols to diagram the program in a flow chart. What are the best practices for the most professional flow-chart? My program is: #include <iostream> #include <fstream> #include <string> #include <limits> using namespace std; string mixColors(int color1, int color2) { string mixedColor; if ((color1 == 0 && color2 == 1) || (color1 == 1 && color2 == 0)) { mixedColor = "purple"; } else if ((color1 == 0 && color2 == 2) || (color1 == 2 && color2 == 0)) { mixedColor = "orange"; } else if ((color1 == 1 && color2 == 2) || (color1 == 2 && color2 == 1)) { mixedColor = "green";…
