I'm not sure if this is the right place to post this but anyway. If u compare c and java which would use less memory, cpu, and take less space??

C

java code is copiled into bytecode. then the java vertiual machine interpets it.

Yeah, C is one of the more fast and efficient languages, especially against Java.

Regarding the size of the program itself, in many cases, the Java program will be smaller, especially if the C program is statically linked.

If you're asking about run-time memory consumption, the C program will probably be smaller by this standard, as it will not require that an associated virtual machine be loaded as well, in order to process the bytecode.

As to performance, the C program will be more efficient, given that all other factors are equal. However, this may or may not have any real-world impact on performance. For example, if the program is input-driven, as it will spend most if its time waiting for the user, and if the Java version supports threads while the C version does not (as will be the case without platform-specific code for the C version), it will be able to suspend threads rather than burn CPU cycles in tight loops while waiting for events, I/O completion, etc.

the above point alludes to the fact that a faster development time (time * paying people to code = cost) may outweigh the performance advantage, particularly if it (cpu usage, etc.) is relatively small. you just have to look at the big picture in the commercial sense.

Thanks thats just wat I wanted to know
@bl00dninja I understand that in the comertial sense a slight performence increas might not be beneficial but the Q was more out of curiosity
