Linux bash shell script

I would like a linux bash shell script (no Perl or any other) to print user information: This shell script has the following specifications: - It must be named: "printpasswd." - It must take one argument from the command line. The argument will point to a file that follows the /etc/passwd format. - It will parse the file and output each user's information in the following format: user-name, uid, gid, home, shell and notes. For example, if the file contains the following information, root:FP3mDXRh.KTMQ:0:0:root:/root:/bin/sh, then the output should be "user-name uid gid home shell notes root 0 0 /root /bin/sh root"

Assignment statement

I need a simple assignment statement with one arithmetic operator in some language you know. For each component of the statement, list the various bindings that are required to determine the semantics when the statement is executed. For each binding, indicate the binding time used for the language.

Comparison of C++ pointers and Java reference

Analyze and write a comparison of C++ pointers and Java reference variables. Use safety and convenience as the primary considerations in the comparison and also consider fixed heap-dynamics variables.

Given a C function show how to derive variable values if expressions are evaluation from left to right or from right to left.

Let the function fun be defined as int fun(int *k) { *k += 4; return 3 * (*k) - 1; } Suppose fun is used in a program as follows void main() { int I = 10, j = 10, sum1, sum2; sum1 = (I / 2) + fun(&i); sum2 - fun(&j) + (j / 2); } What are the values of sum1 and sum2 a. if the operands in the expressions are evaluated left to right? b. If the operands in the expressions are evaluated right to left?
