/* This function finds the first occurence of a character 'int c'

in the string pointed to by 'str'.*/
/* The null terminator character is considered part of the string*/
/*	Removed the condition 'while (str[i])'  and introduced a new variable 
int len that was used to contain the loop within ithe lenght of str	*/
/* The return value is a pointer to the located character or 
Null if the character does not appear in the string*/
/* The return value is the first occurence of the character 
and every other character afterwards */
/* This function imitates the behaviour of the standard Clibrary
