The following program generates an error. Why?

const int NUM$\_$ELEMENTS $=5$;

int userVals$[$NUM$\_$ELEMENTS$]$;

unsigned int $i$;

userVals $[0]=1$;

userVals $[1]=7$;

userVals $[2]=4$;

for NUM$\_$ELEMENTS; $++i)\{$

$\}$

cout $$ userVals $[$i$]$ endl;

The for loop tries to access an index that is out of the array's valid range.

Variable $i$ is declared as an unsigned integer.

The integer NUM$\_$ELEMENTS is declared as a constant.

The array userVals has $5$ elements, but only $3$ have values assigned.
