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 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.'
