This method takes two strings, then first compares the length and then uses memcmp to compare them if the length is identical. Code: int strcomp(char, char); int strcomp(char s1, char s2) { int l1 = strlen(s1); int l2 = strlen(s2); if (l1 == l2) { return memcmp(s1, s2, l1); } else { return 0; } } When ...
