The Terminal on Mac: Coding
So found this C code online and need to compile it in Terminal on Mac.
Here is the code:
Code:
#include <stdio.h>
#include <math.h>
 
int option;
char q;
int number;
int currentsum;
int value;
 
void calc()
{
     printf("\t\t\t\t\tBegin\n"); // says begin in top middle of screen
     option = 0; number = 0; currentsum = 0; value = 0;
     while(1){
              value = getchar(); // gets user input and sets equal to value
              if (value >= '0' && value <= '9')
              {
                 number = number*10 + (value - '0'); /* a way of reading the "values" left to right. If someone puts in 729 as their first number then it will go across
              and do number = 0*10 (because number was set equal to 0) + 7. then it goes through again. number is now 7 so it goes through and does 7*10 + 2 thus making
              72. Number is now 72 which means it goes 72*10 + 9 making number 729. It will follow this process if the input is a number 1-9*/
              }
              if (value == '+' || value == '-' || value == '*' || value == '/' || value == '^' || value == '=' || value == '\n')
              {
                   if(value == '+') currentsum = currentsum + number; // if I come across one of these symbols then it performs the operation described
                   if(value == '-') currentsum = currentsum - number;
                   if(value == '*') currentsum = currentsum * number;
                   if(value == '/') currentsum = currentsum / number;
                   if(value == '^') currentsum = pow(currentsum, number);
                   if(value == '=') printf(currentsum);  // when it reads an equal sign or a new line it displays the result of the equation.
                   if(value == '\n') printf(currentsum);
              }
              else break; // come across any other symbols or characters break the loop     
             }
}
int main()
{
    system("title Calculator"); // titles windo "Calculator
    system("color 1A"); // makes background blue
    calc(); // goes to void calc
    system("pause");
    scanf("%c",&q);
    if( q == 'q')exit(0);
}

Now just to let you know i do not want to use anything else to compile it except for the Terminal.

PERLMACOS(1)						 Perl Programmers Reference Guide					      PERLMACOS(1)

NAME

       README.macos - Perl under Mac OS (Classic)

SYNOPSIS

       This document briefly describes perl under Mac OS (Classic).  If you are running perl under Mac OS X, you don't want to be here (unless you
       are in the Classic environment under Mac OS X).

       When we say "Mac OS" below, we mean Mac OS 7, 8, and 9, and not Mac OS X.

DESCRIPTION

       The latest perl source itself builds on Mac OS, with some additional pieces. Support for Mac OS is now in the perl core, and MacPerl is
       kept in close sync with regular perl releases.

       To build perl for Mac OS (as an MPW tool), you will need the addition of the macos subdirectory, distributed separately.  It includes extra
       source files, config files, and make files.  It also includes extra Mac-specific modules.

       To build the MacPerl application, you will also need the macperl directory, which includes the source files for creating the application
       itself.

       All of this is available from the development site, via HTTP (in the MacPerl Installer, which includes all the source and binaries) and
       anonymous CVS.

	       http://dev.macperl.org/

       The source is also in the main perl repository in the macperl branch (the 5.6 source is in the maint-5.6/macperl branch).

       You will also need compilers and libraries, all of them freely available.  These are linked to from the SourceForge site. Go that site for
       all things having to do with MacPerl development.

       MacPerl 5.6.1 and later are supported on Mac OS 8.1 and later, for 68040 and PowerPC architectures.  The MPW tool may be used on Mac OS
       7.5.5 and 68030 computers.

       MacPerl 5.2.0r4 is also available, on the CPAN and on SourceForge.  It is based on perl 5.004, and works with Mac OS 7.5.5 and 68030 com-
       puters.

AUTHOR

       perl was ported to Mac OS by Matthias Neeracher <neeracher@mac.com>.  It is currently maintained by Chris Nandor <pudge@pobox.com>.
