I need to know how to display all the results from the if(unit==1) section of the code in a table format ?

You haven't really given the format of the table you want but just output each value with a tab '\t' character between each one or alternitively print each value with a fixed width specifier and a following space

         printf("The escape velocity of Mars is: %8.1f km/s\n", ev);
 

Printing a table is just a matter of outputing tabs an spaces so that your columns of figures line up on the screen. No special functions required.
