A couple of C programs that I wrote that do the exact same thing, but are coded a bit different. They both calculate the energy of a bullet. You have to input the weight in grains and the velocity in feet per second. I am learning how to program in C and wanted to try new things.<\/p>\n\n\n\n
The first one uses a struct and has some functions. The second one is much simpler and just has one main function. They both should compile with any C compiler.<\/p>\n\n\n\n
