My C Programs Begin to Work!

Hello all, something really astounding happened!

My C program worked!

It was an exercise question in a C book. To make a calculator that works wit these:

<number><space><sign>

The signs can do these:
S: set the value of the accumulator
/: divide accumulator by number specified
x: multiply accumulator by number
+: you know what
-: //ditto

0 E would end the program:

#include <stdio.h>

int main () {
	float value, number;
	char sign;
	int tmp;

	printf("Begin Calculations\n");
	for ( tmp = 0; ++tmp; tmp > 0 ) {
		scanf("%f %c", &number, &sign);

		switch ( sign ) {
		case 'S': {
			value = number;
			printf("= %f\n", value);
			break;
		}

		case '+': {
			value += number;
			printf("= %f\n", value);
			break;
		}

		case '-': {
			value -= number;
			printf("= %f\n", value);
			break;
		}

		case 'x': {
			value *= number;
			printf("= %f\n", value);
			break;
		}

		case '/': {
			value /= number;
			printf("= %f\n", value);
			break;
		}

		case 'E': {
			printf("= %f\n", value);
			printf("End of Calculations\n");
			return 0;
		}
		}
	}
	return 0;
}

Now is the return statement correct in last case i.e. E? How to use break there?

Break is optional... in this case is not necessary because of return statement.

Congrats... I remembered my first C program too... oh old good times hehehe...

It's not just a C thing. The first program I ever wrote was in basic; it converted centigrade to fahrenheit and backwards. And when I ran it and it actually worked, I knew how God felt on the seventh day. It was that sense of omnipotence: I had told a computer what to do and the computer had actually done it!
