In this example, the programmer sets the value of the msg variable, expecting to reuse it outside the block. Due to the reuse of the variable name, however, the outside msg variable value is not changed.

char msg[100];
{
char msg[80] = "Hello";
strcpy(msg, "Error");
}
printf ("%s\n", msg);

| Code Block |

char error_msg[100]; { char hello_msg[80] = "Hello"; strcpy(error_msg, "Error"); } printf ("%s\n", msg); |
