SECTION V:

We have a C program with the following declarations:

int a$=10,$ b$=5,$ c$=1,$ d$=2$;

double w$=3\mathrm{.}5,$ x$=-5\mathrm{.}0,$ y$=2\mathrm{.}5,$ z$=1\mathrm{.}0$;

What will be the exact output on the screen of the

following statements? A space is indicated with the

character #$.$ For example for the statement printf

$("\%5$d$",$a$)$;$,$ the answer will be ###$10.$ If a result or

expression is invalid, select "none of these".

$14.$ printf $("\%3\mathrm{.}2$lf$",-$a$+$x$)$;

a$)$ ###$-5$ b$)-5\mathrm{.}00$ c$)-5\mathrm{.}0$ d$)-5.$

e$)$ none of these

$15.$ printf $("\%5\mathrm{.}2$lf$",$ y$/$z$)$;

a$)$ ##$2\mathrm{.}5$ b$)2\mathrm{.}50000$ c$)$ #$2\mathrm{.}50$ d$)2\mathrm{.}5$

e$)$ none of these

$16.$ printf $("\%-4$d$",5-$c$/$d$)$;

a$)2$### b$)4\mathrm{.}5$ c$)4$ d$)5$###

e$)$ none of these

$4$

$17.$ printf $("\%4\mathrm{.}2$lf$/",$ z$+$a$*2+$z$-$c$)$;

a$)21\mathrm{.}00/$ b$)22\mathrm{.}00/$ c$)21\mathrm{.}0/$ d$)22\mathrm{.}0/$

e$)$ none of these

$18.$ printf $("3$d$",$ b$+$a$*$a$)$;

a$)150$ b$)$ #$10$ c$)105$ d$)101$

e$)$ none of these

SECTION VI:

Identify the correct C statement to solve the following

problems:

$19.$ Check for a number that is between $1$ and $6$ inclusively.

a$)$ if $(1$ x $6)$ b$)$ if $(1<=$ x $<=6)$

c$)$ if $($x $>=1||$ x $<=6)$ d$)$ if $(1<=$ x && x $<=6)$

e$)$ none of these

$20.$ Check for an even number less than $100.$

a$)$ if $($x $<100||$ x $\%2)$ b$)$ if $($x $/2$ && x $<100)$

c$)$ if $($x $\%2<100)$ d$)$ if $(!($x $\%2)$ && x $<100)$

e$)$ none of these

$21.$ Divide a floating point $($double$)$ number by $10.$

a$)$ x $=$ x $\%10$; b$)$ x $=$ x $/2*5$;

c$)$ x $=$ x $/2/5$; d$)$ x $=$ x $*10/2$;

e$)$ none of these

$22.$ Identify the condition that will always be false.

a$)$ if $(3<$ x $<2)$ b$)$ if $($x $<3||$ x $>=2)$

c$)$ if $($x $<3$ && x $<2)$ d$)$ if $($x $>3$ && x $<2)$

e$)$ none of these

$5$

$23.$ Check for a real number that is a whole number $($for

example, $14\mathrm{.}0$ is a whole number, $3\mathrm{.}57$ is not$).$

a$)$ if $($whole $($x$))$ b$)$ if $($x $==$ ceil$($x$))$

c$)$ if $($floor$($x$)=$ x$)$ d$)$ if $($x $==$ x$)$

e$)$ none of these

$24.$ Ask the user for a whole number followed by a real

number $($with decimal digits$).$

a$)$ scanf $("\%$d $\%$lf$",$ a$,$ b$)$; b$)$ scanf $("\%$lf $\%$d$",$ &a$,$ &b$)$;

c$)$ printf $("\%$d $\%$lf$",$ a$,$ b$)$; d$)$ scanf $("\%$d $\%$lf$",$ &a$,$ &b$)$;

e$)$ none of these
