C String Functions
The following are the list of inbuilt string functions in c programming.
| Functions | Explanation |
|---|---|
| strcat() | Appends the source string to the destination string. |
| strncat() | Appends the source string to the destination string up to the specified length. |
| strcpy() | Copies a string from source to destination. |
| strncpy() | Copies a string from source to destination up to the specified length. |
| strlen() | Determines the length of the given string. |
| strcmp() | Compares the characters of two strings (This function discriminates between lower case and upper case). |
| strncmp() | Compares the characters of two strings up to the specified length (This function discriminates between lower case and upper case). |
| stricmp() | Compares the characters of two strings (This function doesn't discriminates between lower case and upper case). |
| strchr() | Determines the first occurrence of the given character in the string. |
| strrchr() | Determines the last occurrence of the given character in the string. |
| strstr() | Determines the first occurrence of a given string in another string. |
| strdup() | Duplicates a given string at the allocated memory which is pointed by a pointer variable. |
| strlwr() | Converts any string to a lower case. |
| strupr() | Converts any string to a upper case. |
| strrev() | Reverses all characters of a given string. |
| strset() | Replaces every character of a string with the symbol given by the programmer. |
| strnset() | Replaces every character of a string with the symbol given by the programmer up to the specified length. |
| strtok() | Breaks string into a series of tokens using the given delimiter. |
| strerror() | Translates the error code to a suitable string that describes the error. |
| strpbrk() | Searches the first occurrence of the character in a given string and then it displays the string starting from that character. |
| strcoll() | Compares two strings depends upon the LC_COLLATE settings. |
| strspn() | Finds up to what length two strings are identical. |
| strcspn() | Scans string 1 for the first occurrence of any of the characters that are part of string 2. |
| strxfrm() | Transforms the first n characters of source string into current locale and place them in destination string. |
| memchr() | Searches for the first occurrence of the character in a specified number of characters. |
| memmove() | Copies a block of memory from a location to another using an intermediate buffer. |
| memcpy() | Copies a block of memory from a location to another without using an intermediate buffer. |
| memcmp() | Compares the first n bytes of memory area str1 and memory area str2. |
| memset() | Replaces every character of a string with the symbol given by the programmer up to the specified length. |
