Question

this is in C programming language

1. Write a printf or scanf statement for each of the following: a) Print unsigned integer 1001 right justified in a 10-digit field with 5 digits. b) Read a hexadecimal value into variable hex. c) Print 300 with and without a sign. .d) Print 200 in hexadecimal form preceded by Ox. e) Read characters into array m until the letter z is encountered. f) Print 7.350 in a 7-digit field with preceding zeros. B) Read a time of the form hh-mm-ss, storing the parts of the time in the integer variables hour, minute and second. Skip the dash (-) in the input stream. Use the assignment suppression character. h) Read a string of the form "characters from the standard input. Store the string in character array s. Eliminate the quotation marks from the input stream. i) Read a time of the form hh:mm:ss, storing the parts of the time in the integer variables hour, minute and second. Skip the colons (') in the input stream. Do not use the assignment suppression character.

Answer 1

$printf(hour: %d minute: %d second: %d\n, hour, min, sec);$

Since questions were all part of single question, I just wrote a single program for all the questions, please comment if you need separately. Also please comment if you have any doubts and do give a thumbs up if you liked the answer

Part A: Right Justified Output: 1001 Part B: Enter hexadecimal value: ffd Hexadecimal value is: ffd, in decimal: 4093 Part C: Signed: 300, Unsigned: 300, Part D: Hexadecimal: exc8 Part E: Enter character: a Enter character: s Enter character: Z asz Part F: 007.350 Part G: Enter value of date: 06:23:34 hour: 6 minute: 23 second: 34 Part H: "characters" characters Part I: Enter value of time: 06:23:34, hour: 6 minute: 23 second: 34
