Write a function that print the factorial of a given integer number: #! /bin/bash factorial(){ if [ $1 -le 0 ] then echo "please enter a positive integer" else let factorial=1; for ((let i=2; i<$1; i++)) do factorial=$factorial*i done echo $factorial } read -p "enter...

These actually specify the sequence of the instructions to be executed in a program. Also, these control structures help in decision-making and operating with jumping statements. Here is a list of control statements in SHELL scripts: The while loop The for loop The until loop...

The interactive command line program can be used to quickly test some statements, or conduct simple programming to obtain results. 另外,可以用-version参数查看当前谢语言的版本号: In addition, you can use the - version parameter to view the version number of the current Xielang: D:\tmpx>...
Informally, an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output....
