Re: Calculator program in C

Hy, I begun studying c++ a few days ago and I came across this topic and decided to write a similar program in c++...

The code was a bit inspired from the original c calculator :)

Code:

```#include <cstdlib> #include <cstdio> #include <iostream> using namespace std; double x; double y; double multi(double x, double y); double divi(double x, double y); double sub (double x, double y); double add(double x, double y); int main(int argc, char *argv[]) {     char a, z;     for(;;) {     cin>> x; cin>> z; cin>>y; if (z=='*'){cout<<"=" <<multi (x,y)<< endl;} if (z=='/'){cout<<"=" <<divi (x,y)<< endl;} if (z=='-'){cout<<"=" <<sub (x,y)<< endl;} if (z=='+'){cout<<"=" <<add (x,y)<< endl;} cout<<"Would you like to do another operation? [y/n]"; cin>>a; if (a!='y') {break;} }     system("PAUSE");     return EXIT_SUCCESS; } double multi (double x, double y) {return x*y;} double divi (double x, double y) {return x/y;} double sub (double x, double y) {return x-y;} double add (double x, double y) {return x+y;}```
Cheers!

You are using a Cpp compiler and try a C compiler and it would work. For some old TC compiler just renaming the file to .c would compile it for you
