Re: How to Compute Time in C language using time.h?

strncpy(sm,stb+3,2); is because of this time format:
HH:MM
, so if we count from 0, MM begins from 3-rd symbol.
sm[2]='\0'; is because functions like atoi(...) work with null-terminated strings.

For example, this way:

#include <time.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
void main()
{
char stb[1025];
char ste[1025];
char sh[3],sm[3];
tm rtb,rte;
time_t ttb,tte,ttr;
long qh,qm;

printf("Enter Time-in: ");scanf("%s",stb);
printf("Enter Time-out: ");scanf("%s",ste);

rtb.tm_year=111;rtb.tm_mon=0;rtb.tm_mday=1;rtb.tm_sec=0;
strncpy(sh,stb,2);sh[2]='\0';
strncpy(sm,stb+3,2);sm[2]='\0';
rtb.tm_hour=atoi(sh);
rtb.tm_min=atoi(sm);

rte.tm_year=111;rte.tm_mon=0;rte.tm_mday=1;rte.tm_sec=0;
strncpy(sh,ste,2);sh[2]='\0';
strncpy(sm,ste+3,2);sm[2]='\0';
rte.tm_hour=atoi(sh);
rte.tm_min=atoi(sm);

ttb=mktime(&rtb);
tte=mktime(&rte);

ttr=difftime(tte,ttb);
qm=ttr/60;
qh=qm/60;
if(qh)
qm=qm%(qh*60);
printf("Total No. of Working Hours: %02d:%02d\n",qh,qm);
}

I use this way:

package ptCCV;

public class cmain
{
public static void main(String[] args)
{
b ob=new b();
}
}

Maybe I did not understand what you need? Let me know if you have questions!

For example this way:

a.java
package ptCCV;

public class a
{
public String s="abcd";
}

b.java
package ptCCV;

public class b
{
public b()
{
a oa=new a();
System.out.println("e:["+oa.s+"]");
}
}
