Write four functions using the struct type that you declared. 1.An input function: This function takes a pointer to the struct type that you declared. The function prompts the user for two integers and puts them into the struct. 2.An output function: This function takes a pointer to the struct type that you declared. The function prints the number as: numerator / denominator. 3.An add function: This function takes three pointers to the struct type that you declared. Two pointers are to the operands and the third function is for the result. 4.A multiply function: This function takes three pointers to the struct type that you declared. Two pointers are to the operands and the third function is for the result. 5.Write a main function with a loop to test your functions.
