Find the Greatest Time in C or CPP from two different times.

Find the Greatest Time in C or CPP from two different times.
Example Code:
#include<iostream.h>
#include<conio.h>
class time
{
private:
int hh,mm,ss;
public:
void get()
{
cout<<"\n enter hh,mm,ss:";
cin>>hh>>mm>>ss;
}
void show()
{
cout<<"\n hour:"<<hh<<"\n minute:"<<mm<<"\n second:"<<ss;
}
time greatest(time x)
{
if (hh>x.ss)
return *this;
else
if(hh>x.hh)
return x;
else
if(mm>x.mm)
return *this;
else
if(mm<x.mm)
return x;
else
if(ss>x.ss)
return *this;
else
return x;
}
};
void main()
{
clrscr();
time t1,t2,t3;
cout<<"\n enter time1:";
t1.get();
cout<<"\n enter time2:";
t2.get();
t3=t1.greatest(t2);
cout<<"\n greatest time:";
t3.show();
getch();
}

C Code Shortening Techniques or My Logic for Reduced Source Code Writing in C Program Language

C Code Shortening Techniques or My Logic for Reduced Source Code Writing Tips and Tricks in C Program Language :- Role of Semi Colon(;) and Curly Braces({ }) in C Program Perhaps, you might have heard that the for() loop should not end with ";" like if(). But, in fact the ";" is using in C language as a Statement Terminator, so, if we want to terminate for() loop, then we should use ";" at the end of for() loop. [ Header files are to be included as usual, it is not written in the examples ] Question : write a C program to print 1 to 10 numbers using for() loop ? Example 1 : void main() { int i; for ( i = 1 ; i <= 10 ; i++ ) { printf("%d\n",i); } } /* above program, for() loop has one statement outside, so we do not use ";" at the end, because if we put ";" the for() will not take the continuing statement as its own. */ Example 2 : void main() { int i; for ( i = 1 ; i <= 10 ; printf( "%d \n" , i ...

How to create User Defined Functions in C, see example Perfect_Number() function used as UDF in C Program

How to create User Defined Functions in C, see example Perfect_Number() function used as UDF in C Program :- Example : This is a program to find Perfect Numbers upto a limit using User Defined Function(UDF) in C Program Language :- #include<stdio.h> #include<conio.h> int Perfect_Number(int); /* UDF function prototype declaration : int argument and int returns */ main() { int lmt,num; clrscr(); printf("Enter a Limit :"); scanf("%d",&lmt); for(num=5 ; num<=lmt ; num++) { /* function calls here with Actual Parameter num and returns either 1 or 0 and checks */ if(Perfect_Number(num)==1) { printf("\n%d",num); } } getch(); } /* Either the function should be defined out side the main() or it should be in one of the header files included. function definition with a Formal Parameter as n */ int Perfect_Number(int n) { int a,sm; sm=0; for(a=1 ; a<n ; a++) { if(n%a==0) { sm=sm+a; } } if(sm==n) return 1; else ...
