C code for rational numbers

[sekitoleko]

Thanks for the reply,however,i need to develop a c code that can do both addition and multiplication of rational numbers

[dtimes6]

struct rational {
        int numerator;
        int denominator;
};

struct rational sum( struct rational a, struct rational b) {
	rational c;
	c.numerator = a.numerator * b.denominator + b.numerator * a.denominator;
	c.denominator = a.denominator * b.denominator;
	return c;
}

struct rational multi( struct rational a, struct rational b) {
	rational c;
	c.numerator = a.numerator * b.numerator;
	c.denominator = a.denominator * b.denominator;
	return c;
}
