Given x $<-$ c$(1,2,7,3,6,8,12,13,15,18),$ how do you count the number of even numbers in a vector x using a for loop in R$?$

Question $11$Answer

a$.$

count $<-$ sum$($x $\%\%2==0)$

b$.$

count $<-0$; while $($x $>0)\{$ if $($x $\%\%2==0)\{$ count $=$ count $+1\}$ x $=$ x $-1\}$

c$.$

count $<-0$; for $($val in x$)\{$ if $($val $\%\%2!=0)\{$ count $=$ count $+1\}\}$

d$.$

count $<-0$; for $($val in x$)\{$ if $($val $\%\%2==0)\{$ count $=$ count $+1\}\}$
