While loop in Arduino.ino

Question

Why while loops have problem running in arduino programs ?

Answer 1

I dunno what kind of problem you faced....
The Problem that I can guess....
1.Arduino has the slow spec but cheap that can make many robots(Ok nope That's impossible)
2.You didn't make kind of stop statement for while loop at all

Answer 2

Actually the assumed c code for an arduino IDE blank sketch

void setup(){}
void loop(){}

looks like this:
void setup(void); //function prototypes
void loop(void);

int main(void) {
setup();
while(1) {
loop(); // repeat this over and over again
}
return 0; // this never happens
}

therefore there can't be problems with while loops
