It compares the first count characters of the arrays pointed to by buf1 and buf2.
int memcmp(const void *buf1, const void *buf2, size_t count); Return Value: it returns an integer. Parameters: buf1 : Pointer to block of memory. buf2 : Pointer to block of memory. count : Maximum numbers of bytes to compare. Return Value is interpreted as : Value Meaning Less than zero buf1 is less than buf2. Zero buf1 is equal to buf2. Greater than zero buf1 is greater than buf2.
Example 1. When count Greater than zero( > 0)
Welcome to GeeksforGeeks is greater than Hello Geeks
Example 2. When count less than zero( < 0)
String 1 is less than String 2
Example 3 : When count equal to zero ( = 0)
Welcome to GeeksforGeeks is the same as Welcome to GeeksforGeeks
