HOW TO BUILD A CALCULATOR USING XCODE COMAND LINE TOOL IN OBJECTIVE C?

This Objective C tutorial will hep you to build easy calculator in command line tool, its easy to understand

NOTE: You can change the variable names as you want. In this coding I have used number1, number2 and method as variables

        float number1, number2;

        int method;

        NSLog(@"Enter 1(addition) or 2(subtraction) or 3(division) or 4(multiplication)");

        scanf ("%i", &method);

        NSLog(@"enter two number with spaces between them");

        scanf("%f", &number1);

        scanf ("%f", &number2);

        switch (method) {

            case 1:

                NSLog(@"the sum of number %f and %f is %f", number1, number2, number1+number2);

                break;

            case 2:

                NSLog(@"the subtraction of number %f and %f is %f", number1, number2, number1-number2); 

                break;

            case 3:

                NSLog(@"the division of number %f and %f is %f", number1, number2, number1/number2);

                break;

            case 4:

                NSLog(@"the multiplication of number %f and %f is %f", number1, number2, number1*number2);

                break;

            default: NSLog(@"enter a specific number");

                break;
