Thread: Function retrun type and param list

1.​​​It seems like at least for writting code for microcontroller eval boards that unlike assembler C does not do well with just listing rows and rows of code in "main.c" Seems like functions are the way to go which actually is better and makes a program way esier to read. So if i have a function that calls other functions that do a task like output to a port and they are not returning any results to the calling function for that calling function ,probably a while , do i just put void calling function <void> or do i need a return type calling function <parameter list> ?

2.I have another question, if i create a while and it is while(1) will the while keep executing ? so the code would stop, forever executing the while(1) any statements or functions below the {} of the while(1) would not be executed?

1. If the function is not meant to return a value then declare it to have void return type.

2. Yes.
