use C++ language

search substring in the str(string) and return the index from where it starts. DO NOT use any library functions. int search_substring(std::string& sub, std::string& str); package this above function in a separate file and call it from your main program and link it separately at compile time let us say you wrote your function search_substring() in ss.cpp g++ -C SS.cpp above call will create object file main.cpp is main program g++ -omain main.cpp ss.o Example: str = "This is my computer"; sstr = "my" int i = search_substring(sstr, str); i should 8 in this case. #include #include int seach_substring(std::string& sub, std::string& str) { } int main() { std::string sub = "my"; std::string str = "This is my computer"; int i = seach_substring(sub, str); std::cout
