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.

One should also check for display size, so as to adjust further displaying on it. Macro Definition Documentation #define BRLAPI_MAXNAMELENGTH 31 Maximum name length for names embeded in BrlAPI packets, not counting any termination character Function Documentation int BRLAPI_STDCALL brlapi__getDisplaySize (brlapi_handle_t *handle, unsigned int *x, unsigned int *y) int BRLAPI_STDCALL brlapi__getDriverName (brlapi_handle_t *handle, char *buffer, size_tsize) int BRLAPI_STDCALL brlapi_getDisplaySize (unsigned int *x, unsigned int *y) Return the size of the braille display int BRLAPI_STDCALL brlapi_getDriverName (char *buffer, size_tsize) Return the complete name of the driver used by brltty This function fills its argument with the whole name of the braille terminal if available, terminated with a ''. Parameters: buffer is the buffer given by the application; size is the maximum size for the name buffer. Returns: -1 on error, or a positive value giving the size of the needed buffer, if the supplied one is to small (same as snprintf()).
