Hey i have a mickro c code to measure voltage and current ... i want to run this code on ccs compiler.... please help

Code: 
// LCD module connections
sbit LCD_RS at RB5_bit;
sbit LCD_EN at RB7_bit;
sbit LCD_D4 at RC4_bit;
sbit LCD_D5 at RC5_bit;
sbit LCD_D6 at RC6_bit;
sbit LCD_D7 at RC7_bit;

sbit LCD_RS_Direction at TRISB5_bit;
sbit LCD_EN_Direction at TRISB7_bit;
sbit LCD_D4_Direction at TRISC4_bit;
sbit LCD_D5_Direction at TRISC5_bit;
sbit LCD_D6_Direction at TRISC6_bit;
sbit LCD_D7_Direction at TRISC7_bit;
// End LCD module connections



char look(int a)
{
   switch(a)
   {
       case 0:
              return '0';

Thanksss so much

- - - Updated - - -

when i run this command... i got an error printf format type is invalid

Code: 
printf(lcd_putc,"Voltage = %LuV",volt);
 

Sorry volt and current are string so use %s instead of %Lu

printf(lcd_putc,"Voltage = %sV",volt);

Similarly

printf(LCD_PUTC, "Current = %sA",current);
 

Please recommend me some books to understand CCS

Thanks it worked
 

The Compiler was giving no error but proteus simulation was not displaying anything... here are the changes that i made... now its working Alhamdulillah

Code: 
#include <16F877a.H> 
#device adc=10 
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)

#include <lcd2.c>

char look(int a)
{
switch(a)
{
case 0:
return '0';
case 1:
return '1';
case 2:
return '2';
case 3:
return '3';
case 4:
return '4';
case 5:
return '5';
case 6:
return '6';
case 7:
return '7';
case 8:
return '8';
case 9:
return '9';
default:
return '.';
}
}


void main()
{

lcd_init();
unsigned int16 v,vp,ip,i;
Char *volt = "00.0";
Char *current = "0.00";
set_tris_a (0xFF);
do
{
setup_adc_ports(AN0);

vp = v;
ip = i;
volt[0] = look(v/10000);
volt[1] = look((v/1000)%10);

lcd_gotoxy(1,1);

When i am compiled get 3 errors as "A numeric expression must here"
