C Strchr Function Char *strchr ( const char *s, int c ); i understand that strchr locates the first occurrence of character c in string s. if c is found, a pointer to c in s is returned. The strchr function locates the first occurrence of c (converted to a char) in the string pointed to by s. the terminating null character is considered to be part of the string.
Rewrite C Function Strchr Quizcoder The second argument is an int for reasons of backwards compatibility between the old pre standard code for strchr() and the c89 c90 standard version. the standard says: the strchr function locates the first occurrence of c (converted to a char) in the string pointed to by s when searching for equality, it doesn't matter much whether it is converted to plain char (which may be signed or. The strchr function in the c standard library looks for a char in a string, but its signature takes an int for the search character. in these two implementations i found, the implementation casts. I am trying to use the strchr function to test and see if the last character in the string is one of the punctuation marks using a if loop within a for loop. however when i run the program it seems to skip the if loop all together. It simply subtracts str, which is a pointer to the first character of the string, from the pointer to the found result. this then becomes the position of the character, indexed from 0. this is easy to understand, if the character is found in the first position of the string, the returned pointer will be equal to str, and thus (pstr str) == 0 is true. adding one makes it 1 based, which is.

For this i try using strchr to locate the spaces. but the second time i use strchr i need an offset to find the second space. i tried the following: pose=strchr(mystring b 1,' '); pose=strchr(&mystring[b 1],' '); the variables b and e should contain the positions of the space character in mystring. word2 should contain quick eventually. The obvious (?) way is of course to use the return value of strchr () as the new string, after adding 1 to step past the occurrence known to be there, yes. something like:. The strchr () index () function locates the first occurrence of c in the string pointed to by s. the terminating null character is considered to be part of the string; therefore if c is '\0', the functions locate the terminating '\0'. Strchr expects that the first parameter is null terminated, and hence doesn't require a length parameter. memchr works similarly but doesn't expect that the memory block is null terminated, so you may be searching for a \0 character successfully.
