//I am writing a program that converts from one unit like mm to another e.g cm. The program should prompt invalid unit when something other than mm, cm, m or km is entered as the unit to be converted from or unit to be converted to. The problem is how I initialize the units. When debugging, input ends the program. What do I do? //Program to shows conversion of units #include <iostream> // for cin, cout #include <string> #include <cmath> using namespace std; int main() { char init_unit[2], sec_unit[2]; //declaration of the conversion units double conv_val; //declaration of the number …

Hi. I am interested in converting an amount of pixels into a real cencimenter or inch value. I´ve read some articles which confused me more that they informed me, so hope you can guide me in the right direction :) Lets say I have a user input his monitor size (in inches) and his current resolution. Would I then be able to calculate how many inches/cencimeters, lets say a 1000 pixels, would be? Thanks alot for your time :)
