(Solved) : Exercise 1 50 Points Write Versions Strlen Strncat Functions Described Text See Screenshot Q28594848 . . . .

Exercise 1 (50 points): Write your own versions of the strlenand strncat functions described in the text. (See the screenshot ofthe function descriptions given below.) Write a function namedremovechr that removes all occurrences of the specified characterfrom a string. All three of these functions will use pointers andpointer arithmetic. (You may not use array subscripts anywhere inyour functions.) Your removechr function will be prototyped asfollows:

char *removechr(char *string, const char ch);

The function removechr removes all occurrences of a characterfrom a string and returns a pointer to the modified string. Pleasenote it does modify the string that is its first argument and
