Error in Code? [C] -

i'm stuck in infinite loop, reason program doesn't terminate when \n entered. point of code reverse input, i'm trying using pointer instead of integer keep track of position in array.

#define msg_length 80  int main(void) {     char msg[msg_length], *p;      printf("enter message: ");      (p = msg; p < &msg[msg_length];)     {         *p++ = getchar();          if (*p == '\n')             break;     }      printf("reversal is: ");      (p--; p >= msg;)         putchar(*p--);      return 0;  } 

for (p = msg; p < &msg[msg_length];) {     *p++ = getchar(); <-- getting character in *p , incrementing p      if (*p == '\n')   <-- checking value of next character, not 1 read         break; } 

possible correction:

for (p = msg; p < &msg[msg_length]; p+=sizeof(char)) {     *p = getchar();      if (*p == '\n')         break; }
