What type can be used to replace templates from this function?

template<class T, class U>
T func(T a, T b, U c)
{
	if(c == '+' || c){
		return a+b;
	}
	else if(c == '-' || !c){
		return a-b;
	}
}

A. Size of a data type in bits B. Size of a data type in bytes C. Size of a variable in bytes D. Size of a variable in bits

A. Char B. Float C. String D. Double

A. To declare a variable with dynamic storage duration B. To declare a constant C. To declare a variable with external linkage D. To declare a variable with static storage duration

A. None of the above B. They both have the same effect C. '++i' increments the value of 'i' before returning it, while 'i++' increments the value of 'i' after returning it D. '++i' increments the value of 'i' after returning it, while 'i++' increments the value of 'i' before returning it
