<DIV></DIV>&gt; 
<DIV></DIV>&gt;signed integer variables can store both positive and negative variables, 
<DIV></DIV>&gt;unsigned only positive. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;e.g. 
<DIV></DIV>&gt;int x; 
<DIV></DIV>&gt;signed int x; // They are both the same 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;unsigned int x; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;long y; 
<DIV></DIV>&gt;signed long y; // They are both the same 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;unsigned long y; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;In the case of int the "int" can be avoided: 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;int x; 
<DIV></DIV>&gt;signed x; // They are both the same 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;unsigned x; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Also normally we do not use signed but only unsigned when we need so: 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;int x; // signed 
<DIV></DIV>&gt;long y; //signed 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;unsigned z; // unsigned int 
<DIV></DIV>&gt;unsigned long y; 
<DIV></DIV>&gt;unsigned char c; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;But a char it can be signed or unsigned. It depends from the system. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;E.g. char c; // it can be signed or unsigned 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;signed char c; // signed 
<DIV></DIV>&gt;unsigned char c; // unsigned 
<DIV></DIV>&gt;

<DIV></DIV>&gt; &gt; What do unsigned and signed do to variables?
