Thread: How to use tolower command for a string??

How to use tolower command for a string??

for example:

printf("Please inout the word for convert:");


scanf("%s", result);

result[6]=tolower( result[6]);


ptr = strcmp(result, word );


how come the program can work, but it doesn't convert?

the variable result (a string), iz the 1 which i wan to convert.
the variable word (a string) is the 1 which i wan to compare with. So no matter the content of result iz a big letter, ir a small letter, the compare result will still be the same.

pls help mi..~~
thanx

You will probley need to convert each element seperatly in a character array. But I wounder how it would handle a string type.

Code:

cout << "\nEnter string: ";
	cin >> userInput;

		for (int i = 0; i < strlen(userInput); i++)
	{
		userInput[i] = tolower(userInput[i]);
	}

thanx guys
especially RoD,

it really help mi alot, i'v finish my project

example below:


printf("How many chances you wish to have?? (MAXIMUM is 20)\n");
scanf("%d", &chance);


If the user ACCIDENTALLY hit a alphabet on the keyboard, the program will have error, as the input must be an integer...

How can i prevent the error even the user click in an alphabet, and also it need to be a %d at the same time?

iz there a way to prompt the user to enter again as the input muz be an integer???
