Switch inside while and break statement

Suppose I have a piece of C code

     while(1)
     {
         switch(a){
         case 1:
           if(b==1)
             break;//first break
           break;//second break   
         }    
     }

Will the second break get me to continue the while(1) loop and the first break get me to break out of the while(1) loop even though the first break is inside second break?

The order seems to be changed here on breaks. What is the C language implementation standard on this?

C 2024 6.8.7.4 says:

A break statement terminates execution of the innermost enclosing switch or iteration statement.

Therefore a break whose innermost enclosing switch or iteration statement is a switch statement terminates execution of that switch statement.
