C++ Program to do Addition,subtraction and multiplication of two numbers using function

#include<iostream.h> #include<conio.h> int res; void main() { clrscr(); int sum(int,int); int sub(int,int); int mul(int,int); int a,b,m,su,s; cout<<“Enter two numbers:”; cin>>a>>b; s=sum(a,b); su=sub(a,b); m=mul(a,b); cout<<“Sum:”<<s<<“nSubtraction:”<<su<<“nMultiplication:”<<m; getch(); } sum(int a,int b) { res=a+b; return(res); } sub(int a,int b) { res=a-b; return(res); } mul(int a,int b) { res=a*b; return(res); }
