write a scripting to return values in functions
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.
int 2n(int n){return n << 1;)
Sure: int main (void) { puts ("Hello, world"); return 0; }
If you write out the functions before you write main, you will probably have to return to the functions after outlining main and correct them so that they interact with main as they should. In the long run, it is far better to write main first, so that you understand exactly what you want each function to do before you write the function, so that you don't have to go back and correct them.
It returns the value to the operating system or whatever process launched it. If you launched your program from a batch file then the batch file can detect this return value. If your program is spawned or launched by another program then the return value goes to that parent prgoram or process. One more thing is that you can write main() without the return type and it will be absolutely correct

You can write a program without specifying its prototype when the function returns an integer.If the prototype is not mentioned the compiler thinks that the return type of the function used is integer.When making program which return integer you can ignore writing the protoype.

To write an exponent on a laptop you would use the "^" key. For example, "3^2" would be "three squared."
9 cubes in exponent form = 93
1) Write a loop to multiply "x" by itself, "n" times. 2) Use recursion. If your function is called "myPower", then if the exponent is 1, return "x". Otherwise return myPower(x, n - 1). 3) But in general, and especially if you want to calculate non-integral powers, it's best to use the functions already included in the C language.
