Skip and copy Function assistance

New programmer here. I need some help. So basically what im trying to do here is to copy certain parts of 1 string stored in an array into 3 different arrays by ignoring the "," in the string. I'll show you the code to be more clear.

#include<stdio.h>
 #include<string.h>
 
 main()
 {
     char temp[50];
     char temp1[50],temp2[50],temp3[50];
     int i,m;
     strcpy(temp,"abc,123,rio");
     for(i=0;i<strlen(temp);i++)
     {
         //printf("%c\n",temp[i]); 
         if (temp[i]==',')
         temp[i]=='';
         else
         temp1[i]=temp[i];
     }
     printf("%s\n",temp1);
     return 0;
 }
 

Now the problem comes in at the part where it says "temp[i]==''"
I know that line is wrong. But i need some help there. I want to be able to skip the "," and move on to copy 123 in temp2 and rio in temp 3. So far i was only able to copy abc into temp1. I don't know exactly how to "Skip and copy" the rest. Please help fast ! :]
