1. Find the solution to the following
a. (110 110 000)2 = ( ? )8
b. (1000 1100 0000 1100)2 = ( ? )16
c. (0011.10111)2 = ( ? )10
d. (123)8 = (? )10
e. (ABCD)16 = ( ? )10
f. (12.3)8 = ( ? )10
g. (ABCD)16 = ( ? )8
h. (98.7)8 = ( ? )16
i. (12.45)10 = ( ? )2
j. (0 10001001 1100000000000000000000) in FP = ( ? )10
k. (134.50)10 = ( ? ) in FP using 32 bit
2. Write a C program that accepts a character input and an integer value as the key.
Add the key to the ASCII value of the character and print the equivalent character.
3. Write a C program to determine the sum of the following sequences
a. Arithmetic sequence
๐๐= ๐
2[2๐1+(๐ โ 1)๐] where n is the number of terms, ๐1 is the first term and
d is common difference.
b. Geometric sequence
๐๐= ๐1(1โ๐ ๐)
1โ๐ where n is the number of terms, ๐1 is the first term and r is
common ratio.
Solve the following problems using formatted input and/or formatted output only.
4. A C program contains the following statements
#include <stdio.h>
char text[] = โThis is C Programmingโ;
Write a printf() function that will allow the contents of text to be displayed in the
following ways.
a. Entirely on one line.
b. Only the first eight characters.
c. Only the first eight characters, preceded by five blanks.
d. Only the first eight characters, followed by five blanks.
