Second, my program has problems. I've discovered a horrible way (for me anyway) to design and my attempts to fix it aren't getting any where. I have to design a roman numeral calculator (input romans, output romans) with at least two functions (decimal->roman, roman->decimal). I started by designing … Re: roman numeral calculator problems 16 Years Ago by robotnixon My output being in the right format means it looks like this after running it: Enter a roman expression X + X = Enter a roman expression. Post #3 has the old output. I had changed all of the romanNums to roman and sum is initialized as 0 in convertToDecimal. I did what you suggested with cout statement, and my output was 50 lines, with… Re: roman numeral calculator problems 16 Years Ago by robotnixon [QUOTE=Salem;476612]# int convertToDecimal(string&) # { # char roman[20]; Try int convertToDecimal(char roman[20]) Or better yet, make roman your std::string variable.

Re: roman numeral calculator problems 16 Years Ago by Lerner Intinalize sum to zero in convertToDecimal() before you try to add something to it. You never use the values passed to convertToDecimal() in the form of roman. Instead, you ask for additional input in the form of romanNum.

Instead, you ask for additional input in the form of romanNum.[/QUOTE] I'm not sure I understand this part.

I used the length member function to read … Re: roman numeral calculator problems 16 Years Ago by robotnixon I changed this: [inlinecode] int convertToDecimal(string&) { char roman[20]; int length = strlen(roman); [/inlinecode] My output is in the correct format but there's no answer. Re: roman numeral calculator problems 16 Years Ago by Lerner >>My output is in the correct format but there's no answer. I'm not sure what this means.
