hello, I made a circuit 7segment display, and I want to display a rotation time (seconds) from 0 seconds to 60 seconds but I found a calculation problem, I have 01 seconds between each display, and when the the display shows the number 9 after it displays the number 0, not 10, 11, 13 ..... so help me

char display_digit[10]= {0xbF,0x6,0x5b,0x4f,0x66,0x6D,0x7D,0x7,0x7f,0x6F};
while (1)
{
OUTPUT_B(0x00);
OUTPUT_A(0xFF);
for (Dec=0;Dec<=5;++Dec)
{
for (unit=0;unit<=9;++unit)
{
OUTPUT_A(0x01);
OUTPUT_B(display_digit[unit]);
delay_ms( 100 );
if (Dec==0) output_high(PIN_A1);
else OUTPUT_A(0x02);
OUTPUT_B(display_digit[dec]);
}
}
