Hello People,
I need help because i just need to figure out whats wrong with the code i wrote for my program.. i tried to figure it out but i'm stuck. So here it is and i would appreciate it if someone can set me strait. Thanx alot.
Well here it is..
I am writing a program that computes the number of days between two dates.
It gives me a couple of error messages.
I don't know what i'm not using write or what i'm doing wrong!!
Please help me... Thanx again.

Use code tags.

split it up into smaller, easier to comprehend chunks (iow, use what you learned about methods, classes, etc.).

That should unstick you probably.

If not think of how you'd do it without a computer. Write that down, then translate it into computer code one bit at a time (again, taking care to split it up into small chunks you can comprehend as a single entity).

Okay so i should shorten my code? Well i did as best as i could on it and i only get three errors that say something about the std::basisstring thingy. i am using atoi to do the numbering and i'm not sure if i need to change that particular thing.. But i'll see if i can shorten it ..Thanx..

atoi requires const char*as an argument. string is a specialization of basic_string and is not a const char*. Call method c_str() on the string to get const char*. string owns the memory for the char buffer, so make sure your string goes out of scope after you have finished with the cons char*. The lines

inDay1Int=atoi(inDay1);
inYear1Int=atoi(inYear1);
inDay2Int=atoi(inDay2);
inYear2Int=atoi(inYear2);

should be

inDay1Int=atoi(inDay1.c_str());
inYear1Int=atoi(inYear1.c_Str());
inDay2Int=atoi(inDay2.c_str());
inYear2Int=atoi(inYear2.c_str());

Also, variable inMonth2Char is used bit not set anywhere.
