Chaning AM to PM and vice versa

Hello once again,

So here is the part of my code I am having a problem with:

Code:

---


if (daynight=="AM" && hour == 12 && minute ==00)
          {
              strcpy(daynight, "PM");
          }
         
          if (daynight=="PM" && hour ==12 && minute ==00)
          {
              strcpy(daynight, "AM");
          }

---

So what I essentially get is :

11:58PM
11:59PM
12:00PM
12:01PM

when the latter two should be AM.

Can someone please help me with this? Thank you so much

You can't compare strings with "==". Use strcmp(), or in your case, you could hard-code the toggling of 'A' and 'P'.

example:

Code:

---

if (hour == 12 && minute == 0) {
    if (daynight[0] == 'A') {
        daynight[0] = 'P';
    } else {
        daynight[0] = 'A';
    }
}

Or something like that.

Thank you so very much. with your tip to use strcmp and some examples from google, I changed my code to the following and it worked great..

Code:

---

          if (strcmp(daynight,"AM") && hour == 12 && minute ==00)
          {
              strcpy(daynight, "PM");
          }
         
          if (strcmp(daynight,"P M") && hour ==12 && minute ==00)
          {
              strcpy(daynight, "AM");
          }

Thank you so much. You saved me.
