This is the continuation of the article String
Manipulation Functions (string.h) in which we’re discussing about
the string manipulation functions.
Here I have listed 8 functions along with their prototype (simplified) and
a short description.
One thing to note here is that unlike the last article on this topic, I have
not included example programs, since the functions (with their prototypes) are
pretty much straightforward.
strlwr:
Prototype: char *strlwr(char *)
This function converts the given string to lowercase and returns the same.
strupr:
Prototype: char *strupr(char *)
This function converts the given string to UPPERCASE and returns it.
strncat:
Prototype: strncat(char *str1, const char *str2, int n)
It appends first ‘n’ characters of str2 to the end of str1.
strncpy:
Prototype: int strncmp(char *str1, const char *str2, int n)
This function compares first ‘n’ characters of str1 with str2,
it returns 0 if compare was successful.
stricmp:
Prototype: int stricmp(const char *str1, const char *str2)
It compares two strings str1 and str2 without regard to case and returns
0 on being successful.
strnicmp:
Prototype: int strnicmp(const char *str1, const char *str2, int n)
This function compares first ‘n’ characters of str1 with str2
without regard to case.
strrev:
Prototype: char *strrev(char *)
This function reverses the given string and returns it.
stcstr:
Prototype: char *strstr(const char *str1, const char *str2)
This function returns the pointer to where the first occurrence of string
str2 is found inside str1.
Good-Bye!
