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 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.
