You get the error messages because you are trying to define functions inside the main function. Functions are not allowed to be defined inside other functions. You should put the function definitions outside of main.

Good day sir. Could you give an example of how it should be. So that i can get an clear idea on it .

[Peter87]

At the moment you have it like this.

int otherFunction(); // function declaration

int main()
{
	int otherFunction() // function definition
	{
		// ...
	}
}

You should do it like this instead.

int otherFunction(); // function declaration

int main()
{
	
}

int otherFunction() // function definition
{
	// ...
}

Sir, do you mean like this:

int addVehicle();

int main()

{

        // . . .

}

int addVehicles()

{
       // . . .
}

[Peter87]

Yes, but this is just so that you get the idea. The dots have to be replaced by code.

In your original post, maybe you just forgot to put an end to the main function using } before you defined addVehicle(). Also note that a function definition should not have a semicolon after the parentheses.

This is wrong

void addVehicle();
{
	// ...
}

This is right

void addVehicle()
{
	// ...
}

Thank you sir. Much appreciate it. :)
