The strcspn() function in C/C++ takes two string as input, string_1 and string_2 as it’s argument and searches string_1 by traversing for any characters that is present in string_2 . The function will return the length of string_1 if none of the characters of string_2 are found in string_1 . This function is defined in cstring header file .
size_t strcspn ( const char *string_1, const char *string_2 )
Parameters : The function accepts two mandatory parameters which are described below:
- string_1: specifies the string to be searched
- string_2: specifies the string containing the characters to be matched
Return Value : This function returns the number of character traversed in string_1 before any of the character matched from string_2 .
Below programs illustrate the above function:
The number of characters beforethe matched character are 12
