1. Write a program that prompts the user to enter a number n, then prints all even squares between 1 and n. For example, if the user enters 100, the program should print the following:

4

16

36

64

100

1. Write your program here:

#include

int main(){

return 0;

}

2. Write a program that prints a one-month calendar. The user specifies the number of days in the month and the day of the week on which the month begins:

Enter number of days in month: 31

Enter starting day of the week (l=Sun, 7=Sat): 3

		1	2	3	4	5
6	7	8	9	10	11	12
13	14	15	16	17	18	19
20	21	22	23	24	25	26
27	28	29	30	31

Hint: This program isnt as hard as it looks. The most important part is a for statement that uses a variable i to count from i to n, where n is the number of days in the month, printing each value of i. Inside the loop, an if statement tests whether i is the last day in a week; if so, it prints a new-line character.

2. Write your program here:

#include

int main(){

return 0;

}
