[...]	Read a character string. The characters inside the brackets indicate the allow-able characters that are to be contained in the string. If any other character is typed, the string is terminated. If the first characteris a ^, the remaining characters inside the brackets indicate that typing them will terminate the string.
*	this is used to skip input fields


	int number;
	char text1[30], text2[30];

	scanf("%s %d %*f %s", text1, &number, text2);

If the user response is,

	Hello 14 736.55 uncle sam

then

	 text1 = hello, number = 14, text2 = uncle

and the next call to the scanf function will continue from where the last one left off, so if

	scanf("%s ", text2);

was the next call, then

	 text2 = sam
