how can i get c to only accept 1 character for an input. i have a menu system 1-5 using a switch statement but when i put in 12345 or someting similiar it still accepts the first number as 1 and executes the number 1 menu.im pretty new to c so any help is much appreciated.thx

look into getchar()

#include <stdio.h>

int main(void)
{
  printf("Menu 1\n");
  printf("Menu 2\n");
  printf("Menu 3\n");
  printf("Menu 4\n");
  printf("Menu 5\n");
  
  switch(getchar())
  {
    case '1':
      //...
      break;
      
    default: 
      //...
      break;
  }  

  return 0;
}
