coding
1) (2Points) Write all the code necessary to allow a person at the keyboard to enter a string and
then print that string.
2) (10Points) Write all the code necessary to allow a person to enter a number grade (from 0 to
100) on the keyboard and then print out the corresponding letter grade according to the
following grade guidelines.
90-100 A
80-89 B
70-79 C
60-69 D
otherwise F
3) (5Points) Write a for-loop that prints out all the numbers from 1 to 15 on separate lines,
printing one line per loop execution.
