# std::strchr

From cppreference.com
< cpp‎ | string‎ | byte

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 `ch` in the byte string pointed to by `str`.

The terminating null character is considered to be a part of the string.

### [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 NULL if no such character is found.

### [edit] 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)) != NULL) {
        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.'
