Question

I want to handle some char variables and would like to get a list of some functions that can do these tasks when it comes to handling chars.

• Getting first characters of a char (var_name[1] doesnt seem to work)
• Getting last characters of a char
• Checking for char1 matches with char2 ( eg if “unicorn” matches words with “bicycle”

I am pretty sure some of these methods exist in libraries such as stdio.h or so but google isnt my friend.

EDIT:My 3rd question means not direct match with strcmp but single character match(eg if “hey” and “hello”) have e as common letter.

Answer 1

• Use var_name[0] to get first character (array indexes run from 0 to N - 1, where N is the number of elements in the array).
• Use var_name[strlen(var_name) - 1] to get the last character.
• Use strcmp() to compare two char strings.

EDIT:

To search for character in a string you can use strchr():

if (strchr("hello", 'e') && strchr("hey", 'e'))
{
}

There is also strpbrk() function that would indicate if two strings have any common characters:

if (strpbrk("hello", "hey"))
{
}

_{Assuming you mean a char[], and not a char which is a single character.}
