Give an example of an operationin a programming languagethat is implemented.
i) directly
ii) as a subprogram
iii) as an inline code

(i) #include <iostream>  

using namespace std;  

int main() {  

int n1,n2,max;  

cin>>n1>>n2;  

if(n1>n2)//finding maximum between n1 and n2 in the program directly.  

max=n1;  

else  

max=n2;  

cout<<max;  

return 0;  

}  

(ii)  

#include <iostream>  

using namespace std;  

int maximum(int n1 ,int n2)  

{  

if(n1>n2)//finding maximum between n1 and n2 using function.  

return n1;  

else  

return n2;  

}  

int main() {  

int n1,n2,max;  

cin>>n1>>n2;  

max=maximum(n1,n2);  

cout<<max;  

return 0;  

}  

(iii)  

#include <iostream>  

using namespace std;  

inline int maximum(int n1 ,int n2)  

{  

return (n1>n2)? n1:n2;  

}  

int main() {  

int n1,n2,max;  

cin>>n1>>n2;  

max=maximum(n1,n2);//Finding maximum using inline function.  

cout<<max;  

return 0;  

}  

Output:-  

54 78  

78  

all three codes give the same output.  

Explanation:  

In part (i) I have done the operation in the main function directly.  

In part(ii) I have used function to calculate the maximum.  

In part(iii) I have used inline function to calculate maximum.
