整型变量数值范围练习

<p> <span style="font-family:SimSun;">请按以下要求编程，体会整型变量能存放数据的大小范围</span> </p> <table style="width:300px;" border="1" cellspacing="0" bordercolor="#000000" cellpadding="2"> <tbody> <tr> <td> <p> <span style="font-family:SimSun;">&nbsp;定义a b c d e f g 七个整形变量。（int类型）</span> </p> <p> <span style="font-family:SimSun;">将常数1234567890保存到变量a</span> </p> <p> <span style="font-family:SimSun;">将常数2147483646保存到变量b</span> </p> <p> <span style="font-family:SimSun;">计算b+1并将结果保存到变量c</span> </p> <p> <span style="font-family:SimSun;">计算c+1并将结果保存到变量d</span> </p> <p> <span style="font-family:SimSun;">将常数-2147483647保存到变量e</span> </p> <p> <span style="font-family:SimSun;">计算e-1并将结果保存到变量f</span> </p> <p> <span style="font-family:SimSun;">计算f-1并将结果保存到变量g</span> </p> <p> <span style="font-family:SimSun;">输出"a="以及变量a的值</span> </p> <p> <span style="font-family:SimSun;">输出"b="以及变量b的值</span> </p> <p> <span style="font-family:SimSun;">输出"c="以及变量c的值</span> </p> <p> <span style="font-family:SimSun;">输出"d="以及变量d的值</span> </p> <p> <span style="font-family:SimSun;">输出"e="以及变量e的值</span> </p> <p> <span style="font-family:SimSun;">输出"f="以及变量f的值</span> </p> <p> <span style="font-family:SimSun;">输出"g="以及变量g的值</span> </p> </td> </tr> </tbody> </table> <p> <span style="font-family:SimSun;">&nbsp;</span> </p> <p> <span style="font-family:SimSun;">提示：</span><span style="font-family:SimSun;">部分样例输出</span><br /> <span style="font-family:SimSun;">a=1234567890</span><br /> <span style="font-family:SimSun;">b=2147483646</span> </p> <p> &nbsp; </p> <p> <span style="font-family:SimSun;">命令 </span><span style="background-color:#cccccc;font-family:SimSun;"><strong>k=5+j</strong></span><span style="background-color:#cccccc;font-family:SimSun;"><strong>;&nbsp;</strong></span><span style="font-family:SimSun;"> 表示计算5+变量j的值，并将计算结果保存到变量k</span> </p> <p> <span style="font-family:SimSun;">命令 </span><span style="background-color:#cccccc;font-family:SimSun;"><strong>cout&lt;&lt;"k="&lt;&lt;k&lt;&lt;endl;</strong></span><span style="font-family:SimSun;"> 将输出 k=以及变量k的值</span> </p> <p> <span style="font-family:SimSun;">int类型的变量只能存放-2147483648到2147483647之间的整数，</span> </p> <p> <span style="font-family:SimSun;">大于2147483647的数存入int类型变量将出现溢出</span> </p> <p> <span style="font-family:SimSun;">小于--2147483648的数存入int类型变量将出现溢出</span> </p> <p> <span style="font-family:SimSun;">请观察数据溢出后的数值大小（变量d，变量g的值）</span> </p> <p> <span style="font-family:SimSun;">&nbsp;</span> </p>
