I am having trouble on my mbed (c++) with getting a program to work properly.

How would I take 1000 samples from a temperature sensor and have it display the highest temperature when it finds one? I will press a button and after i press it, I need it to display a high temperature on a serial display on my computer (i know how to get it to the display, but am not sure how to get the high out of 1000 samples).

Here is what I have so far and it keeps giving the high temperature as 0:

float temp[]; float highTemp = 0; void record(void) { // displays the record high temperature for (int i = 0; i < 1000; i++) { temp[i] = ((sensor*3.3)-0.500)*100.0; if (temp[i] > highTemp) { temp[i] = highTemp; } } pc.printf("Highest Temperature = %5.2f C ", highTemp); wait(0.5);

}

sensor is the data coming from the temperature sensor, i am displaying it to Tera Term on my computer to see the high when i click the button. I cannot figure out how to click the button once and have it continue to display instead of me clicking it and only displaying while the button is pressed down. I also need to know how to set up the array correctly so it does not display 0.
