why does the execution of a c++ program start with main()???

Answer Posted / sujith

Typically all programs that is written using C or C++ have
a global header called C Runtime headers. This is inserted
to the beginning of programs. So when you start the program
the function that is called always is, _CRTMain(). This
function will call the main function. Why every function to
start with main? Well, it is not true that all functions
should start with main. There are ways to call a user
defined function before main using #pragma starup etc.
Still mostly the entry point for all functions are main.
The reason why it is given like that is, it is essential
that _CRTMain has to give control to the user defined
functions through some way. Main is that function, and why
it is named as main is because that is the "main" function
which _CRTMain calls.

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
