This assignment gives an opportunity to practice pointer and string manipulation. You should not call any existing string function from C++ string library. You need to implement three function defined as I do in copy function. 

//compare string s1 and s2, return 1 if s1>s2, return –1 if s1<s2,  //return 0 if s1 equal to s2 int strcmp(const char* s1,const char* s2); 

//return the string length of string s int length(const char* s); 

//return the number of times character “c” in string “s” int countChar(const char* s,const char c); 

The main function is provided as:
