Note!

Only write the missing functions with C++

Below program asks user for three integers and prints the smallest and largest of those three on screen. Your task is to write the missing functions (largest() and smallest (), which receive the user input as parameters and return the largest and smallest integers, respectively. Incomplete program: #include using namespace std; int largest(int first, int second, int third); intsmallest(int first, int second, int third); int main() { int number1, number2, number3, largestnumber,smallestnumber; cout > numberl; cout > number2; cout > number3; largestnumber = largest(number1, number2, number3); smallestnumber =smallest(number1, number2, number3); cout
