interfacing of 7 segment with 8051

C code for 0-9 display on 7 segment:

#include<reg51.h>

unsigned int i, j, k;

void delay( );

unsigned char arr[]=(0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x47,0x7f,0x6f);

 void main( )

 {

 for(i=0;i<=9;i++)

 {

 P1=arr[i];

delay();  

}

}

void delay( )

{

for(j=0;j<=60000;j++);

}
