(True or False) Determine whether each of the following is true or false. If false, explain why,
a) To refer to a particular location or element within an array, we specify the name of the array and the value of the particular element.
b) An array definition reserves space for an array.
c) To reserve 100 locations for integer array p, you write
p[100];
d) A for statement must be used to initialize the elements of a 15-element array to zero.
e) Nested for statements must be used to total the elements of a two-dimensional array.

(Duplicate Elimination with array) Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the array only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Provide for the 'worst case' in which all 20 numbers are different. Use the smallest possible array to solve this problem.

The program should verify that the user entered a number and that the high number is higher than the low number for a month. Function averageHigh: This function calculates and returns the aver- age high temperature for the year. Function averageLow: This function calculates and returns the average low temperature for the year. Function indexHighTemp: This function returns the index of the highest high temperature in the array. Function indexLowTemp: This function returns the index of the lowest low temperature in the array. These functions must all have the appropriate parameters. INPUT…arrow_forward
