Recursion
Write the recursive function print_multiples(int max) that prints the multiples of 7 between 7 and max, in descending order. Assume that max is a multiple of 7.
The function call:
print_multiples(98);Would produce the output:
98
91
84
77
70
63
56
49
42
35
28
21
14
7Write the recursive function print_powers(int max) that prints the powers of 2, in ascending order, that are less than or equal to max. Assume that max is a power of 2.
The function call:
print_powers(64);Would produce the output:
1
2
4
8
16
32
64The function call:
print_powers(1024);Would produce the output:
1
2
4
8
16
32
64
128
256
512
1024Write the recursive function prompt(int min, int max) that repeatedly prompts the user to enter an integer until the user enters an integer in the range [min,max].
The function call:
prompt(0, 100);Might produce the output:
Enter an integer in the range [0, 100]: -1
Enter an integer in the range [0, 100]: 101
Enter an integer in the range [0, 100]: 0The function call:
prompt(0, 10);Might produce the output:
Enter an integer in the range [0, 10]: -1
Enter an integer in the range [0, 10]: 11
Enter an integer in the range [0, 10]: 5What does your implementation of prompt do when min is equal to max?
How about when min is greater than max?
Write the recursive function print(int array[], int n) that prints the first n numbers in the array. Assume that
n is at least 0 and less than the size of the array.
The function call:
Let a be the array {8,12,13,4} of size 4.
print(a, 2);Would produce the output:
8 12
print(a, 4);Would produce the output:
8 12 13 4
print(a, 0);Would output nothing.
