| strcat | Concatenates two string |
| strncat | Appends not more than n characters of a string into another string |
| strcpy | Copies one string into another string |
| strncpy | Copies n characters of a string into another string |
| strcmp | Compares two string. If the first string is lexographically less than the second, a value less than zero is returned. If the first is lexographically greater than the second, a value greater than zero is returned. And zero if the two strings are equal. |

| strchr | Returns a pointer to the first occurrence of a character in a string |
| strrchr | Returns a pointer to the last occurrence of a character in a string |
