In a structure, each component occupies a distinct memory space. In a union, all members share the same memory space. This fundamental distinction defines the difference between union and structure.

The continue statement transfers control to the next iteration of the closest enclosing loop (do, for, or while). It skips any remaining statements in the loop body. After executing continue;, the while loop’s condition is promptly evaluated.
