Thread: C Programming Question

Uh, that's nat that simple!

You have to write a parser on your own. In the book "C++ Complete Reference", Herbert Schildt discribes how to write such a parser...

Are you the same one who's posted this question 3 times already? Do something like the following to parse the string entered by the user then use your favorite switch statement to do the calculation.

Code:

int main(){
	char array[] = "x+x*3", *p = &array[0];
	char y = '5';

	while(*p != '\0'){
		if(*p == 'x')
			*p = y;
		p++;
	}

	puts(array);

	return 0;
}
