dealing math in string with C.
firstly so thankful for the prior replys for my last post.
I have done all the code with this programme.
yet my code still seem too heavy and mess much.Code:the program is about /* dealing a string in a way like " A + B = ? ",till the result equals to zero. it requires: A and B are all below 100 number; A or B should be used in " zero " to " nine " english word. using blank space to make sure which one is A or B; readin string ,but not output the result until result equals to zero; output all the result at one time,except the result-zero; here is a example one + two = seven + ten = zero + five = two two + three four = zero + zero = three one seven five five six */
how to make it brief and clean?
appreciate anyone can edit my code.thx!!!!!!!!
