problem in string display

rak men

#include<reg51.h>
#include<string.h>
#include<stdio.h>
#define lcd_data P1
sbit rs=P2^0;
sbit rw=P2^1;
sbit en=P2^2;
unsigned char n[5]="hello";
unsigned char m[]="welcome rakesh";
void cmd_lcd(unsigned char);
void write_lcd(char);
void delay(unsigned int);
void lcd_int()
{ cmd_lcd(0x38); cmd_lcd(0x0c); cmd_lcd(0x01); cmd_lcd(0x80);
} void cmd_lcd(unsigned char x)
{ x=lcd_data;
rs=0;
rw=0;
en=1;
delay(50);
en=0;
}

void write_lcd(char s)
{

s=lcd_data;
rs=1;
rw=0;
en=1;
delay(500);
en=0;
} void delay(unsigned int temp)
{ unsigned int i,j;
for(i=0;i<255;i++);
for(j=0;j<temp;j++);
}

void main()
{ void lcd_int(); void write_lcd(n); void delay(500); void cmd_lcd(0x01); void delay(100); void write_lcd(m); void delay(100);
}

this code shows following error:
Build target 'Target 1'
compiling lcdc04.c...
LCDC04.C(50): error C161: 'n': formal parameter ignored
Target not created

please help me in clearing this...

    He also added:

    (Rakesh mate. look at the void.)

    Not a bad clue.

    That he did. After twice claiming the opposite. And when he finally admitted his mistake, he made every effort to avoid it being noticed: an extremely vague hint, in parentheses, in the middle of an unrelated argument.

    That's not a clue: it's somebody doing his best to avoid the notion that he proclaimed nonsense twice in a row, now hedging his bets by dropping a vague hint pointing in the direction of where he's now beginning to see his mistake must have lain.
