| <H2>22.5 Computed Assignment Operators</H2> |
| <A NAME="idx470"><!></A> |
| <P>Class <B><I><A HREF="../stdlibref/valarray.html">valarray</A></I></B> offers two different versions of the following operators: <SAMP>operator*=()</SAMP>, <SAMP>operator/=()</SAMP>, <SAMP>operator%=()</SAMP>, <SAMP>operator+=()</SAMP>, <SAMP>operator-=()</SAMP>, <SAMP>operator^=()</SAMP>, <SAMP>operator&=()</SAMP>, <SAMP>operator|=()</SAMP>, <SAMP>operator<<=()</SAMP>, and <SAMP>operator>>=()</SAMP>. In each case, one version takes a <B><I>valarray</I></B> reference and the second takes a <SAMP>T&</SAMP>. The first version of each operation applies its operation to the corresponding elements of self and the <B><I>valarray</I></B> argument. The second version applies the operation to all elements of self using the <SAMP>T&</SAMP> argument. For example:</P> |
| |
| <UL><PRE> |
| |
| std::valarray<long> v1(1,3); // v1 = {1,1,1} |
| std::valarray<long> v2(2,3); // v2 = {2,2,2} |
| v1 += v2; // v1 = {3,3,3} |
| v2 += 2; // v2 = {4,4,4} |
| </PRE></UL> |
