    compare two strings

    whats the best way for comparing 2 string to check if they are equal
    i know that 1 ways is with strcmp(string1,string2) but i want to compare them, first with upper and lower letters make them different and second without upper and lower sensitivity
    1st: "test Test" == the same
    2st:"test Test"== different
    strcmp always check the upper and lower option

    Write your own function in which you will test each pair of characters in both strings. You can use one of these functions from ctype.h :

    You can also compare each character with ASCII values to determine upper and lower.

    You could also look into using
    strcasecmp, strncasecmp - case-insensitive string comparisons
