Hi I need some help doing this, I have no idea how to do it, can someone please write the code using C++

56. void total(int value1, value2, value3) { return value1 + value 2+ value 3; \} 57. double average(int value1, int value2, int value3) \{ double average; average=value1+value2+value3/3; \} 58. void area(int length =30, int width ) { return length * width; \} 59. void getValue(int value\&) f cout "Enter a value: "; cin value\&; \} 60. (Overloaded functions) int getValue() { int inputValue; cout "Enter an integer: "; cin inputValue; return inputValue; \} double getValue() { double inputValue; cout "Enter a floating-point number: "; cin inputValue; return inputValue; 2. Examine the following function header, then write an example call to the function: void showValue(int quantity) 3. The following statement calls a function named half. The half function returns a value that is half that of the argument. Write the function. result = half ( number)
