/prog/ - Starting C++, calculator

Name: Anonymous 2007-04-18 5:18 ID:cwaeIkIV

In c++. Every calculator I have seen is just like "enter two numbers to have them added" I want it to just keep giving me the option to keep adding (or whatever operation i choose) numbers until i want it to stop.

fail, do you realize this is EXPERT PROGRAMMERS AREA and you are asking for a calculator?
Plus, if one wants to write a calculator, one must first know the basics of the language he uses.
I bet you don't even know half of the basics of C++

int calc(char *math) {

    char *p;

    int a, b;

    if((p=index(math,'+'))==NULL) exit(-1) // fag

    a = atoi(math);

    b = atoi(p+1);

    return a + b;

}

    

int main() {

    

    char shiz[40];

    int lolwut = 0;

    while(1) {

        cout << "Enter your shiz: ";

        cin >> shiz;

        lolwut += calc(shiz);

        cout << "Answer iz " << lolwut += calc(shiz) << endl;

    }

    

    

}
