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円'.

[edit] Parameters
str
-
pointer to the null-terminated byte string to be analyzed
ch
-
character to search for
[edit] Return value
Pointer to the found character in str, or a null pointer if no such character is found.
[edit] Example
Run this code
#include <cstring> #include <iostream> 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 location ++result; } }
Output:
Found 'T' starting at 'Try not. Do, or do not. There is no try.' Found 'T' starting at 'There is no try.'
