Time Sum Using Structure in C/C++ Language

Problem

Create a structure called time. Its three members, all type int, should be called hours, minutes, and seconds. Write a program that prompts the user to enter a time value in hours, minutes, and seconds. This can be in 12:59:59 format, or each number can be entered at a separate prompt (“Enter hours:”, and so forth). The program should then store the time in a variable of type struct time, and finally print out the total number of seconds represented by this time value:

long totalsecs = t1.hours*3600 + t1.minutes*60 + t1.seconds

Code

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#include<string.h>

struct time {
int hours;
int minutes;
int seconds;
};

//function prototype
void add (int,int,int,int,int,int);

int main()
{
    struct time t1,t2;
   
    //1st time
    printf ("Enter 1st time.");
   
printf ("\n\nEnter Hours: ");
scanf ("%d",&t1.hours);

printf ("\nEnter Minutes: ");
scanf ("%d",&t1.minutes);

printf ("\nEnter Seconds: ");
scanf ("%d",&t1.seconds);

    printf ("\n\nThe Time is %d:%d:%d",t1.hours,t1.minutes,t1.seconds);
   
    //Second time
    printf ("\n\n\nNow, please type the 2nd time.");
   
    printf ("\n\nEnter Hours: ");
scanf ("%d",&t2.hours);

printf ("\nEnter Minutes: ");
scanf ("%d",&t2.minutes);

printf ("\nEnter Seconds: ");
scanf ("%d",&t2.seconds);

    printf ("\n\nThe Time is %d:%d:%d",t2.hours,t2.minutes,t2.seconds);
   
    //function call
    add (t1.hours,t1.minutes,t1.seconds,t2.hours,t2.minutes,t2.seconds);
   
printf ("\n\nPress any key to exit.");
getch();
return 0;
}

//function definition
void add (int x,int y,int z,int a,int b,int c)
{
     int h,m,s;
   
     h = x + a;
     m = y + b;
     s = z + c;
   
     printf ("\n\n\nSum of the two time's is %d:%d:%d",h,m,s);
}
