Write a function char findx const char s const char x that

Solution

Here is the program and please let me know if any errors occurs

char* findx (const char* s, const char* x)

{

assert(s);

assert(x);

size_t len_s = m_strlen(s);

size_t len_x = m_strlen(x);

assert(len_s >= len_x);

char* p_to_match = nullptr;

for (size_t i = 0; i < len_s; ++i)

{

if (*(s + i) == *x)

{

p_to_match = const_cast<char*>(s + i);

if (len_x == 1) return p_to_match;

const char* next_s = (s + i + 1);

const char* first_x = (x + 1);

for (size_t j = 0; j < len_x - 1; ++x)

{

if (*(next_s + j) != *(first_x + j)) break;

if (j == len_x - 2) return p_to_match;

}

}

}

return nullptr;
