            }
            
            else 
            {

    Maybe if you gave each expression in your diagram a different name, it would help when you saw the code.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Like so - for you to finish off...
    Code:
    if ( E1 ) {
      if ( E2 ) {
        S2;
      } else {
        S21;
      }
    } else {
      if ( E3 ) {
      } else {
      }
    }

    alright I am converting logic into code but I am surprised that you did not use the else if statement

    Code:
    #include<stdio.h>
    
    int main ()
    {
    	int n = 3;
    	
       if ( n == 1 )
    	   {
             if ( n == 2 )
    			 { 
            		 printf(" 2 \n");
    				 } 
    				 else 
    				 {
                        printf(" 23 \n");
                     }
                 }
     else 
     {
      if (n == 3 ) 
      {
    	   printf(" 3 \n");
      } 
      else 
      
      {
    	   printf(" 4 \n");
      }
    }
    
    
    return 0;
    }

    > but I am surprised that you did not use the else if statement
    That would imply that you have more than true/false at some level.

    Code:
    if ( n == 1 ) {
    } else if ( n == 2 ) {
    } else {
    }
