Stick with it! you will soon be rewarded with satisfaction of seeing your ideas realised, and your skills will grow quickly, i would recommend declaring all the variables you plan to use at top of main for now, to avoid the confusion explained earlier

Arcantos247: the 'd' has to be outside the {}'s because a variable doesn't exist after the curly-bracket that closes the scope it is in. E.g. Code: { int d; // d exists here { int e; // e exists here, and so does d } // e does not exist here, but d still does { int f; // f exists here, and so does d } // neither e nor f exist here, but d still does } // all of the above variables no longer exist here

I think these operations don't modify the left-hand argument.

Ah, right. I was thinking of something else. My mistake.

Well since you seem to understand how to get the hours, you just need to know how many minutes are left over. There is a "mod" (modulo/modulus) operator that gives you the remainder after a division. So the remainder after dividing 90/60 is 30, which is exactly what you want. So just look up an example of how to use it. The actual operator is "%", and is used just as any other binary operator (+, -, /,...

No, I am not talking about parsing C++ code. I am talking about linking to precompiled source code during runtime. The interpreted language thing was kind of a side question, I was wondering if it would be a better alternative for my project than linking at runtime. This project is a little experimental GUI toolkit using Xlib, and I thought that linking to a seperate piece of code that draws the widgets during runtime would be a good way to...
