Use the colon (':'
) to indicate a labeled statement:
start: x=0; ... goto start;Special case of labels are case-labels, which are used in multiple selection statements, for example,
switch (a) { case 1: puts("One"); break; case 2: puts("Two"); break; ... default: puts("None of the above!"); }Note: The GNU C allows creating of local labels, which are useful in macro definitions.
