How can we write a program which orders the elements of a board given there language of programming c plus plus?
In C++ you can use the standard library sort algorithm to sort any data sequence provided the elements support the appropriate comparison operator (std::less<T> for any given type T is used by default). For example: std::vector<int> v {5, 9, 7, 1, 3}; std::sort (v.begin(), v.end()); // v = {1, 3, 5, 7, 9} std::sort (v.begin(), v.end(), std::greater<int>); // v = {9, 7, 5, 3, 1}
How can write a c plus plus program to sort an integer array and name array using function overloading use dynamic memory allocation for both the array?

How much is a wind power generator?
The cost of installing a home wind power generator depends on the kilowatt it produces. A 1 kilowatt wind power generator usually costs $3000-$7000. A 7 kilowatt wind power generator costs $20,000-$40,000. The more kilowatt it produces, the more costly it is.
Can a5500 watt generator run a 1 horse power motor?
Yes, a 5500 watt generator should be able to run a 1 horsepower motor. A typical 1 horsepower motor requires around 750-1000 watts to operate, so the generator's output should be sufficient. Just make sure to check the starting wattage of the motor to ensure the generator can handle any initial surge in power.

How do you size a generator to operate a pump that draws 7 amps on each leg of a 240 Volt Circuit?
At 240 volts, and 7 amp current, you will have a load of 1680 watts (volts x amps = watts). A 2000 watt generator will sufice, however a 3500 watt generator, if within your budget, will power a few other necessities if required.
