problem in string display

#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...

  • The problem wasn't that he missed an important issue with the line. The problem was that he came back again, a second time claiming that a call was made

    On that we obviously disagree. Yes, he missed an important issue at first. But he also raised a perfectly valid (and arguably equally important) issue. He also added:

    (Rakesh mate. look at the void.)

    Not a bad clue.

    I just hope that the negative responses he received do not deter him from attempting to be helpful in the future.
