Question

#include <iostream>
using namespace std;
int main()
string add='+',sub='-',div='/',mul='*';
char +,-,/,*;
{{cin <<"fn"; <<"type"; <<"sn";
if (type=='+') {add=fn+sn;
cout <<add;}
if(type=='-'){sub=fn-sn;
cout <<sub;}
if(type=='*') {mul=fn*sn;
cout <<mul;}
if(type=='/'){
div=fn/sn;
cout <<div;}
else{cout<<"error";}}
return 0

Answer 1

// ffs

#include <iostream>
using namespace std;

int main()
{
int fn;
int sn;
char type;

cin >> fn;
cin >> type;
cin >> sn;

if (type=='+')
{
cout <<fn+sn;
}
else
if(type=='-')
{
cout <<fn-sn;
}
else
if(type=='*')
{
cout <<fn*sn;
}
else
if(type=='/' && sn != 0)
{
cout <<fn/sn;
}
else
{
cout<<"error";
}

return 0;
}

Answer 2

#include <iostream>
using namespace std;
int main()
{
float ans;
int fn,sn;
char type;
cin>>fn;
cin>>sn;
cin>>type;
if (type=='+') {ans=fn+sn;
cout <<ans;}
if(type=='-'){ans=fn-sn;
cout <<ans;}
if(type=='*') {ans=fn*sn;
cout <<ans;}
if(type=='/'){
ans=float(fn)/sn;
cout <<ans;}
return 0;
}
