battery %

[kmtompkins]

i can tget this to work i dont know how to make it be if between two numbers ex. if answer between 10 and 20 than true

#include <Windows.h>
#include <iostream>

using namespace std;

int main()
{
	while (true)
	{
		SYSTEM_POWER_STATUS status;
		GetSystemPowerStatus(&status);

		int life = status.BatteryLifePercent;

		cout << "Battery staus is:";

		if (life <= 20) // i want this if % is less than or equal to 20
		{
			cout << " low, your should consider charging your battery" << endl;
			Sleep(10000);
			continue;
		}
		else if (life >= 50 <= 79) // i want this if % is greater than or equal to 50 and less than or equal to 79
		{
			cout << " ok, should still consider charging your battery" << endl;
			Sleep(10000);
			continue;
		}
		else if (life >= 80 <= 99) // i want this if % is greater than or equal to 80 and less than or equal to 99
		{
			cout << " average, shouldnt need to charge your battery" << endl;
			Sleep(10000);
			continue;
		}
		else if (life == 100); // i want this if % is egual to 100
		{
			cout << " great, battery is full" << endl;
			Sleep(10000);
			continue;
		}
	}
}

[long double main]

You have to split it up into two separate comparisons:

if (life <= 20)
    // ...
else if (life >= 50 && life <= 79)
    // ...
else if (life >= 80 && life <= 99)
    // ...
else if (life == 100) // No semicolon here
    // ...
