Question: Write a single statement to accomplish each of the following. Assume that variables c (which stores a character), x, y and z are of type int, variables d, e and f are of type double, variable ptr is of type char * and arrays s1[100] and s2[100] are of type char.
a) Convert the character stored in variable c to an uppercase letter. Assign the result to variable c.
b) Determine whether the value of variable c is a digit. Use the conditional operator as shown in Figs. 8.2-8.4 to print " is a " or " is not a " when the result is displayed.
c) Determine whether the value of variable c is a control character. Use the conditional operator to print " is a " or " is not a " when the result is displayed.
d) Read a line of text into array s1 from the keyboard. Do not use scanf.
e) Print the line of text stored in array s1. Do not use printf.
f) Assign ptr the location of the last occurrence of c in s1.
g) Print the value of variable c. Do not use printf.
h) Determine whether the value of c is a letter. Use the conditional operator to print " is a " or " is not a " when the result is displayed.
i) Read a character from the keyboard and store the character in variable c. j) Assign ptr the location of the first occurrence of s2 in s1.
k) Determine whether the value of variable c is a printing character. Use the conditional operator to print " is a " or " is not a " when the result is displayed.
l) Read three double values into variables d, e and f from the string "1.27 10.3 9.432".
m) Copy the string stored in array s2 into array s1.
n) Assign ptr the location of the first occurrence in s1 of any character from s2.
o) Compare the string in s1 with the string in s2. Print the result.
p) Assign ptr the location of the first occurrence of c in s1.
q) Use sprintf to print the values of integer variables x, y and z into array s1. Each value should be printed with a field width of 7.
r) Append 10 characters from the string in s2 to the string in s1.
s) Determine the length of the string in s1. Print the result.
t) Assign ptr to the location of the first token in s2. Tokens in the string s2 are separated by commas (,).
