Tcl introduction and features, Tcl introduction features 【Introduction | features] LIntroduction Tcl was a language developed from the end of 1980s. Like Python, it was developed from c. If C/Java/C ++/C # Is a compiled language, python, Perl, and Tcl are an explanatory language. That is to say, the program can run dir

I. OverviewThe Shell, like other programming languages, supports a variety of operators, including: Arithmetic operators Relational operators Boolean operator String operators File Test Operators Second, arithmetic operatorsNative bash does not

Automated Testing-TCL scripting language, automated-tcl scripting language TCL is a scripting language. It was first called "Tool Command Language" "Tool Command Language", but it does not mean it now, but we still call it TCL. Created by John Ousterhout. TCL is very studiou

Reprinted: http://www.cnblogs.com/chengmo/archive/2010/10/11/1847515.html As one of the excellent tools for text processing, awk has its own rich operators. The following is a summary of all operators. Can be divided into: Arithmetic Operators, value assignment operators, Relational

First, practice1. Binary Turn Decimalproc b2d {b} { set0; Set len [string length $b] for {set0} {$i $len} { incr i} { int([string index $b $i]*pow (2, $len-$i-1)] } return $sum}2. Decimal Turn binaryproc D2B {d} { set"" while {$d! =0} {set " [expr $d%2] $b " set d [Expr $d/2] } return $b}3. Convert from length to subnet maskproc Len2mask {len} {SetMask"" for{SetI0} {$i 4} {incr i} {if{$len >=8} {lappend mask [b2d [FORMATB8 8] ] incr len-8

First, the practice of random numbers1. Randomly generate an integer between the maximum and the minimum valueproc Random {min max} { return [expr round (($max-$min) *rand () +$min)] }2. Generate a random integer that is not duplicated between Num min to maxProc randomunique {min Max num} {Array set arr {}#如果要求生成的数量超过max和min相减的个数 +1If {$num >[expr $max-$min +1]} {Return ""}#当生成的随机数量没有达到要求的数量, call a function that generates a random integerWhile {[Array size arr]Set x [Random $min $max]Set

1, Android smart phone brush machine We usually use the tool, here we recommend the use of "Brush Master" bar, first installed in a computer brush machine master 2, the installation of the TCL no 3S mobile phone and computer connected, and then open the computer in the "Brush Master" as shown in the figure we click on "More Tools" 3, in order to prevent data loss we can backup the mobile phone data, click more tools = = Backup Master

Assignment operatorsThe PHP assignment operator is used to write values to variables. The base assignment operator in PHP is "=".This means that the right-hand copy expression sets the value for the left-hand operand.___________________________________________________________________________________________________Arithmetic character (+-*/%)There are 4 mathematical operations symbols for arithmetic and mathematical operators, including: "+" (plus), "

First, Introductionstring is TCL There are a number of string manipulation commands in the base data type. A more important problem is pattern matching, which matches strings to the specified pattern (format) by pattern matching for string comparisons, searches, and so on. Ii. List of STRING commands Command Description string ByteLength Str Returns the number of bytes used to store the string. strin

1 we found in Tcl s720t "Settings" click to enter, as shown in the figure, and then in the settings list to find "about the phone" below the "version number" We use our fingers to connect click 4 times, as shown in the picture 2 waiting for the prompt to open the USB success, we go back to the phone's "settings", you will find a miracle happened, see the "Developer option", into the "developer option" can be opened, then you want to do what you do.

1. Arithmetic operators Common arithmetic operators Type of operation Operator Example Results Take inverse operation - -$a Returns a negative value of $ A Addition operation + $a + $b Returns $ A with $b and Subtraction operations - $a-$b Returns the difference between $ A and $b Multiplication opera

Precautions: Constants are assigned at compile time, and variables are allocated in memory when they are run. Assignment operator + =-+ *+%= \= The Java compiler enforces type conversions Residual:In Java, it is time to take the remainder operation, and the sign of the result is determined by the divisor.logical operators | or!
