$2.$ Exploring envp: a$.$ Modify showEnvp.c so it reports envp addresses in the same style as showArgs$2$ displays argv addresses. Save a copy of the output in a file $$ you$$ll need to refer to it in part b$.$ Provide a program listing, a status statement and $6-8$ lines of output, but not all the output. $(2)$ b$.$ Inside your program use putenv to define one environment variable and setenv to redefine another. Do these values appear in the array envp or $\_\_$environ or both? $(2)$ c$.$ Based on the program output sketch a data structure diagram for envp. You only need to include the first $3$ environment variable values $(2)$ Hand in a commented listing of your program, proof of testing and a status report. On your cover page, aside from your name, the course code, lab section and the assignment #$.$ Make sure you include your student number. If I have to look it up to verify that you are doing the correct exercise $-2$ marks off. If you do the wrong exercise $2$ more marks will be deducted showEnvp.c #include #include #include #include int main$($int argc, char $*$ argv$[],$char $*$ envp$[])$ int i; fprintf$($stdout$,"$My name is
