ECE347_HW10_C_languageECE347 - Extra HW on C language  1.  Write a C language main function that multiplies two integers a and b, with the result being stored in a long integer.  Use some aitrary numbers for testing.           2.  Re-write the above problem such that the main function initializes a and b, then calls a function that uses a and b as input parameters, performs the multiplication, and returns the long esult.              3.  What is the Code Waior name used to identify the data direction register, bit 6, on port P?     4.  Write a simple C language function that initializes the GPIO bits on port B, such that bit 7 is an input with pullup enabled, bit 6 is an output, and no other bits are manipulated.

ECE347 - Extra HW on C language 
1. Write a C language main function that multiplies two integers a and b, with the result being stored in a long integer. Use some arbitrary numbers for testing. 
#include 
int main()
{
	int a,b;		// two integer numbers
	long int c;		// two long integer numbers
	// get two numbers from user
	printf("Enter two integer numbers:
");
	scanf("%d%d", &a, &b);
	// multiply two integers and store result into a long integer
	c = a * b;
	// show result
	printf("The result is: %li
", c);
	return 0;
}
2. Rewrite the above problem such that the main function initializes a and b, then calls a function that uses a and b as input parameters, performs the multiplication, and returns the long result. 
#include 
long int multiplication(int a, int b)
{
	long int c;		// two long integer numbers
	c = a * b;		// multiply two integers
	return c;		// returns long integer
}
int main()
{
	int a,b;		// two integer numbers
	// get two numbers from user
	printf("Enter two integer numbers:
");
	scanf("%d%d", &a, &b);
	// show result
	printf("The result is: %li
", multiplication(a, b));
	return 0;
}
