help me with formatting please! been trying to do it for hours and I can't get it. lol SoS

[victryhard]

please help me with my homework, I am having trouble executing my code correctly . I managed to do everything properly except I'm not sure how to alternate between "*" and "-" as the sample output is asking its doing *'s and then -'s on every line. tried figuring this out for hours and still can't. probably simple. but I've been trying harder than needed. thanks in advance.

This should have been a separate program, to make sure you understood PrintLine.

void PrintLine(int howMany, char symbolToPrint) {
    for ( int i = 1 ; i <= howMany ; i++ ) {
        cout << symbolToPrint;
    }
    cout << endl;
}
int main ( ) {
    PrintLine(20,'*');
    PrintLine(30,'-');
    PrintLine(40,'=');
}

ok so I managed to make some progress with the coding after just checking back in. I found a way to make the * and - read but now im having trouble with writing the printline function definition as it keeps saying function void printline(int, char) already has a body. which I can see at the top but im trying to figure out why it asks for the pl function to be defined at the bottom when I already have at the beginning , I just tried anything / to change it hoping it would work in this example but it hasn't, please help me understand

void PrintLine(int howMany, char symbolToPrint)
{
	for (int i = 1; i <= howMany; i++)
	{
		cout << symbolToPrint;
	}
	cout << endl;

}

	PrintLine(45, '*');
	cout << " Simple C++ Integer Types" << endl;
