multi_var.tcl for {set i 1; set j 10} {$i <= 5} {incr i; incr j -2} { puts "i=$i, j=$j, sum=[expr {$i + $j}]" } This example manages two variables in the loop. i counts up while j counts down. The initialization and increment sections use semicolons to separate...
在Tcl(Tool Command Language)中,for循环是一种常用的控制结构,用于遍历列表(list)中的元素。下面我将详细介绍for循环在Tcl中的基本概念、优势、类型、应用场景,以及如何解决常见问题。 基本概念 Tcl的for循环语法如下: 代码语言:txt 复制 for {init} {test} {incr} {body} { # 循环体 } init:初始化表达式,...
