# StrOps::Sub( StrPtr &, char, char )

Substitute instances of one character for another.

Virtual? | No |
Class | `StrOps` |
Arguments | `StrPtr &string` | the string on which to operate
| `target` | the target character
| `replace` | the character with which to replace `target`
Returns | `void` |

## Notes

## Example

    #include <stdhdrs.h>
    #include <strbuf.h>
    #include <strops.h>

    int main( int argc, char **argv )
    {
        StrBuf sb;
        sb.Set( "\tPassword" );

        StrOps::Sub( sb, 'o', '0' );
        StrOps::Sub( sb, 'a', '4' );

        StrOps::Dump( sb );

        return 0;
    }

Executing the preceding code produces the following output:
