In C++<\/a>, the resize function is used to change the size of a container. It can take one or two parameters. When only one parameter is passed, resize will change the size of the container to the specified size. If the new size is larger than the current size of the container, default-constructed elements will be added to the end of the container. If the new size is smaller than the current size of the container, elements will be removed from the end. When two parameters are passed, the first parameter specifies the new size, and the second parameter specifies the initial value of the new elements.<\/p>\n
