Download ZIP /.repository-sidebar Raw problem.md Waring’s prime number conjecture states that every odd integer is either prime or the sum of three primes. Goldbach’s conjecture is that every even integer is the sum of two primes. Both problems have been open for over 200 years. In this problem you have a slightly less demanding task. Find a way to express a given integer as the sum of exactly four primes. Each in...

Next: Preprocessor Options , Previous: Debugging Options , Up: Invoking GCC These options control various sorts of optimizations. Without any optimization option, the compiler's goal is to reduce the cost of compilation and to make debugging produce the expected results. Statements are independent: if you stop the program with a breakpoint between statements, you can then assign a new value to any variable or change the program counter to any other statement in the function and get exactly the results you expect from the source code. Turning on optimization flags makes the compiler attempt to improve the performance and/or code size at the expense of compilation time and possibly the ability to debug the program. The compiler performs optimization based on the knowledge it has of the program. Compiling multiple files at once to a single output file mode allows the compiler to...
