fseek() in C language, is use to move file pointer to a specific position. Offset and stream are the destination of pointer, is given in the function parameters. If successful, it returns zero. If it is not successful, it returns non-zero value.Here is the syntax of fseek() in C language, int fseek(FILE *stream, long int offset, int whence)Here are the parameters used in fseek()stream − This is the pointer to identify the stream.offset − This is the number of bytes from the position.whence − This is the position from where offset is added.whence is specified by one of the following ...

This is a string function in C++ that takes in two strings and finds the first occurrence of any character of string2 in string1. It returns the pointer to the character in string1 if there is any, otherwise returns NULL. This is not applicable for terminating NULL characters.The syntax of strpbrk() is given as follows −char *strpbrk(const char *str1, const char *str2)In the above syntax, strpbrk() returns the pointer to the first character in str1 that matches any character in str2.A program that demonstrates strpbrk() is given as follows.Example Live Demo#include #include using namespace std; int main() {   ...
