Question

In C Programming Language

In this lab you will implement 4 string functions, two using array notation and two using pointers. The functions must have the signatures given below. You may not use any C library string functions. The functions are 1. int my strlen (char s ) - This function returns the number of characters in a string. You should use array notation for this function. 2. int my strcpy (char s [], char t I)- This function overwrites string s by a copy of the characters in string t. The copy should succeed only if the length of s is greater than or equal to the length of t. If the copy succeeds, the function returns 1. If the copy cannot be done, the function should return -1. You should use for this function. array notation 3. charmy strcat (char s.char t -this function dynamically allocates enough memory to hold a new string which will be the concatenation of string s followed by string t. The new string is returned. Strings s and t are not changed. Use pointers for this function. 4. void my strreverse (char s-this function overwrites the contents of string s with the reverse of string s. Use pointers to do the reversing Write a tester function (main) to test all of the above functions. The file with your functions and main should be called lab9.c
