Revision _1
Lets have a quick revision of previous concepts by practicing same question using different methods.
Write a Program to add the number .
Method :1
#include<iostream.h>
#include<conio.h>
void main( ) {
clrscr( ) ;
int numb1 , numb2 , answer ;
cout<<”\n Enter the first number = ” ;
cin>>numb1 ;
cout<<”\n Enter the first number = ” ;
cin>>numb1 ;
answer = numb1 + numb2 ;
cout<<”\n The Result is = ”<<answer ;
getch() ;
}
Method :2
#include<iostream.h>
#include<conio.h>
void main() {
clrscr() ;
int numb[2] , answer ;
cout<<”\n Enter the first number = ” ;
cin>>numb[0] ;
cout<<”\n Enter the first number = ” ;
cin>>numb[1] ;
answer = numb[0] + numb[1] ;
cout<<”\n The Result is = ”<<answer ;
getch() ;
}
Method :3
#include<iostream.h>
#include<conio.h>
void main() {
clrscr() ;
int numb[2] ;
cout<<”\n Enter the first number = ” ;
cin>>numb[0] ;
cout<<”\n Enter the first number = ” ;
cin>>numb[1] ;
numb[0] = numb[0] + numb[1] ;
/* here, first the addition will be performed and then the output
of addition will be stored in numb[0] */
/* Storing the output in numb[0] which will reduce the number
of variable requirement which reduce the memory used . */
cout<<”\n The Result is = ”<<numb[0] ;
getch() ;
}
Method : 4
#include<iostream.h>
#include<conio.h>
void ourfunction ( int a[] ) {
int sum ;
sum = a[0] + a[1] ;
cout<<"\n The result is = "<<
sum ;
}
void main () {
clrscr() ;
int num[2] ;
cout<<"\n Enter the number = " ;
cin>>num[0] ;
cout<<"\n Enter the number = " ;
cin>>num[1] ;
ourfunction ( num )
;
getch() ;
}
Method : 5
#include<iostream.h>
#include<conio.h>
int ourfunction ( int a[] ) {
int sum ;
sum = a[0] + a[1] ;
return sum ;
}
void main () {
clrscr() ;
int num[2] , result ;
cout<<"\n Enter the number = " ;
cin>>num[0] ;
cout<<"\n Enter the number = " ;
cin>>num[1] ;
result = ourfunction( num ) ;
cout<<"\n The result is = "<<result ;
getch() ;
}
Method : 6
#include<iostream.h>
#include<conio.h>
void ourfunction ( ) {
int num[2] , result ;
cout<<"\n Enter the number = " ;
cin>>num[0] ;
cout<<"\n Enter the number = " ;
cin>>num[1] ;
result = num[0] +
num[1] ;
cout<<”\n The
result is = ”<<result ;
}
void main () {
clrscr() ;
ourfunction( ) ;
getch() ;
}
Method : 7
#include<iostream.h>
#include<conio.h>
int ourfunction ( ) {
int num[2] , result ;
cout<<"\n Enter the number = " ;
cin>>num[0] ;
cout<<"\n Enter the number = " ;
cin>>num[1] ;
result = num[0] +
num[1] ;
return result ;
}
void main () {
clrscr() ;
int value ;
value = ourfunction( ) ;
cout<<”\n
The result is = ”<< value ;
getch() ;
}
