| Using the GNU Compiler Collection (GCC): Mixed Declarations |
|---|
Next: Function Attributes, Previous: Cast to Union, Up: C Extensions [Contents][Index]
ISO C99 and ISO C++ allow declarations and code to be freely mixed within compound statements. As an extension, GNU C also allows this in C90 mode. For example, you could do:
int i;
/* … */
i++;
int j = i + 2;
Each identifier is visible from where it is declared until the end of the enclosing block.
