C++ program to add two numbers.

C++ programming code#include

intmain()

{

inta, b, c;

couta >>b;

c =a +b;

cout

#include

/* Function arguments are of different data type */

longadd(long, long);

loatadd(loat, loat);

intmain()

longa, b, %;

loatc, d, &;

couta >>b;

% =add(a, b);

cout

code of functions is same ecept data type, C++ provides a solution to this problem we can

create a single function for different data types which reduces code si!e which is via templates.

C++ programming code for function overloading

#include

usingnamespacestd;

/* Number of arguments are different */

oiddispla&(c$ar/0); print t$e string passed as argument

oiddispla&(c$ar/0, c$ar/0);

intmain()

{

c$arirst/0=" programming";

c$arsecond/0="++ programming";

displa&(irst);

displa&(irst, second);

return!;

oiddispla&(c$ars/0)

{

cout

;our main)is pretty messy and very hard to read+++ &on"t comment on the while'oop

since someone e'se a'ready did -and a%ree &ith him. but sty'istica''y to make your

code more readab'e you &ant to have proper indentation:intmain)

is a mess+ ,he 3 'ines on'y %et e4ecuted i* ch;;ith a goto you have to ana'yCe

the code to determine that you &ant 'oopin% behavior+ >hen someone %'ances at a while

they automatica''y kno& it &i'' 'oop based on the condition inside the while+
