Char * strchr function (const char * str, int c) looks for the first occurrence of the character c (an unsigned char) in the string pointed to by parameter str.

Declare the strchr () function in C

Below is the declaration for strchr () in C:

 char * strchr ( const char * str , int c )

Parameters

str - This is the string to be scanned.

c - This is the character to be searched in str.

Returns the value

This function returns a pointer to the first occurrence of the c character in the str string, or returns NULL if the character is not found.

For example

The following C program illustrates the usage of strchr () in C:

 #include #include int main () { const char str [] = "https://QTM.com/lap-trinh-c/index.jsp" ; const char ch = '.' ; char * ret ; ret = strchr ( str , ch ); printf ( "Chuoi dang sau dau |%c| la: n|%s|n" , ch , ret ); return ( 0 ); }
