The strstr function in c is a predefined function for string handling. is the header file required for string functions. The strstr function in c takes two strings s1 and s2 as arguments and finds the first occurrence of the substring s2 in the string s1. The matching process does not inc...
The strstr() function is a built-in function used to process strings that are handled by library string.h. It is the library that provides us multiple functions to manipulate string. strstr() is used to find the specified main string’s first appearance of the matched substring by searching...

In C, these functions take a const pointer for the first argument. In C++, two overloads are available. The overload taking a pointer to const returns a pointer to const; the version that takes a pointer to non-const returns a pointer to non-const. The macro _CONST_CORRECT_OVERLOADS ...

In the main() function, we created a string str initialized with "India is great country". Then we used the strstr() function to find the specified substring "reat" within the string. The strstr() function is used to find the first occurrence of a specified substring within the string ...

But yes, any strcmp/strlen style function that uses SSE/AVX/etc. without a buffer size parameter, must first read in smaller units until it gets to a 16/32 byte aligned address, after which it can start using SSE/AVX safely without having to worry about faulting even if it reads past ...
