 FIND THE AVG & SUM

 CODE:

#include<iostream>

using namespace std;

int main()

{

int c,a,b;//variables with type int

float d;//variable  with type float

cout<<"program of sum & avg"<<endl;

cout<<"enter the 2 number";

cin>>a>>b;

c=a+b;

d=a+b/2;

cout<<a<<"+"<<b<<"="<<c<<endl;

cout<<"avg"<<"="<<d<<endl;

return 0;

}

    OUTPUT:

2]COVERSION FROM CM TO METER INCHS &FEET”

  

CODE:

#include<iostream>

using namespace std;

int main()

{

float a,b,c,d;

cout<<"program of converssion"<<endl;

cout<<"enter the value in cm";

cin>>a;

b=a*0.01;

c=a*0.0328;

d=a*0.393;

cout<<"in meter"<<b<<"in feet"<<c<<"in inch"<<d;

}

OUTPUT:
