std::strchr
From cppreference.com
| 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 <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.'
