Calculate int and sent result to Array but it Error
PostPosted: Tue Jul 16, 2013 11:25 pm     Reply with quote
I calculate time like this
Code:

int next_time(int16 hr, int16 min, int pos){

lcd_gotoxy(1,2);
DS1307_ReadTime();

int16 minimVal;
int i=0,count = 0,check;
int16 hrk[],mnk[],all[];
int16 now_all;
int16 now_hr,now_min;
int16 a1,a2,a3;

now_hr = bcd2bin(RTC.hr);
now_min = bcd2bin(RTC.min);
   
hrk[pos] = hr;
mnk[pos] = min;
all[pos] =(hrk[pos]*60) ;

minimVal = (hrk[0]*60) + mnk[0];
now_all = (now_hr*60)+now_min;

printf("\r\n\n\n a=%ld, n=%ld",all[pos],hrk[pos]);

when I run this code and send value to function it show like this
Quote:

a=180, n=3
a=735, n=4

if n=4 it should be 240 but why it is 735.
when I comment //now_all = (now_hr*60)+now_min; it show correct result. How to calculate it ? Please help me.

Which size do you expect for the [] arrays? Do you understand what happens for pos > 0?
