Make a function called findOldest. To this function, you will pass either the male or female array. This function will find the oldest employee in the array and return the whole struct to the caller. Assume there is only one employee with that oldest age. Call findOldest with the male array in the main and display only the first name of the oldest employee (use cout in the main). Make a function called giveRaise. A raise percentage is passed to this function as one of the parameters and give the raise to everybody in the array. You will be passing either the male or female array to this function. Call giveRaise in the main with the female array and 5.5 (5.5% raise) and then call printAllEmp to make sure all the female employees received a 5.5 raise. int main () {giveRaise (5.5, ?????????????);}
