我需要使用ofstream打开未定义数量的文件才能写入。文件名的格式应为plot1.xpm,plot2.xpm,plot3.xpm,.... 该程序如下所示: 我不知道我应该在星星中放置什么。
for(m = 0; m < spf; m++){
//some calculations on arr[]
ofstream output(???);
for(x = 0; x < n; x++){
for(y = 0; y < n; y++){
if (arr[x*n + y] == 0)
output<<0;
else output<<1;
}
output<<'\n';
output.close();
}
答案 0 :(得分:1)
使用to_string
:
<body>
<div id="case">
<div id="0" class="box">
<input> </input>
<p class="id">0</p>
<p class="id"></p>
</div>
<div id="1" class="box">
<input></input>
<p class="id">1</p>
</div>
<div id="2" class="box">
<input></input>
<p class="id">2</p>
</div>
<div id="3" class="box">
<input></input>
<p class="id">3</p>
</div>
<div id="4" class="box">
<input></input>
<p class="id">4</p>
</div>
<div id="5" class="box">
<input></input>
<p class="id">5</p>
</div>
<div id="6" class="box">
<input></input>
<p class="id">6</p>
</div>
<div id="7" class="box">
<input></input>
<p class="id">7</p>
</div>
<div id="8" class="box">
<input></input>
<p class="id">8</p>
</div>
<div id="9" class="box">
<input></input>
<p class="id">9</p>
</div>
<div id="10" class="box">
<input></input>
<p class="id">10</p>
</div>
<div id="11" class="box">
<input></input>
<p class="id">11</p>
</div>
<div id="12" class="box">
<input></input>
<p class="id">12</p>
</div>
<div id="13" class="box">
<input></input>
<p class="id">13</p>
</div>
<div id="14" class="box">
<input></input>
<p class="id">14</p>
</div>
<div id="15" class="box">
<input></input>
<p class="id">15</p>
<input></input>
</div>
</div>
如果模式更复杂,您还可以使用std::stringstream
:
input{
outline: none;
border: none;
background-color: transparent;
text-align: center;
font-size: 40px;
width: 80px;
height: 80px;
font-family: Verdana, Geneva, sans-serif;
margin: 0;
}
