.push_back(

.push_back()是一个在vector（向量）中添加元素的方法。它将一个元素添加到vector的末尾。可以将要添加的元素作为参数传递给.push_back()方法。例如，如果我们有一个int类型的vector，我们可以使用vec.push_back(10)将整数10添加到vector的末尾。同样，如果我们有一个string类型的变量str，我们可以使用str.push_back('d')将字符'd'添加到字符串的末尾。这个方法对于在vector或字符串的末尾添加元素非常有用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
