std::strchr(3) C++ Standard Libary std::strchr(3) NAME std::strchr - std::strchr Synopsis Defined in header <cstring> const char* strchr( const char* str, int ch ); char* strchr( char* str, int ch ); Finds the first occurrence of the character static_cast<char>(ch) in the byte string pointed to by str. The terminating null character is considered to be a part of the string and can be found if searching for '\0'. Parameters str - pointer to the null-terminated byte string to be analyzed ch - character to search for Return value Pointer to the found character in str, or a null pointer if no such character is found. Example // Run this code #include <iostream> #include <cstring> int main() { const char *str = "Try not. Do, or do not. There is no try."; char target = 'T'; const char *result = str; while ((result = std::strchr(result, target)) != nullptr) { std::cout << "Found '" << target << "' starting at '" << result << "'\n"; // Increment result, otherwise we'll find target at the same loca- tion ++result; } } Output: Found 'T' starting at 'Try not. Do, or do not. There is no try.' Found 'T' starting at 'There is no try.'
