management colleges and int universities. Calculate total

colleges and display the state, which is having highest number

of colleges.

ANS)
#include<stdio.h>
#include<conio.h>

7) Define a structure by name time with members seconds,

minutes and hours of int type. A variable of the structure

would thus represent time. If time1 and time2 are two

variables of the structure type, write a program to find the

difference of two times using a function.

    dispay(t2);
    printf("\n answer = ");
    dispay(ans);
    }
    getch();
}
void dispay(struct tm tmp)
{
    printf("\n %d:%d:%d",tmp.hh,tmp.mm,tmp.ss);
}
void sub(struct tm t1,struct tm t2,struct tm *p )
{


if(t1.ss>=t2.ss)
{
p->ss=t1.ss-t2.ss;
