Answer 1

// Note: Below are the corrected statement with incorrection marked after // for eg ; is missing

Ans a)

   if ( sales >= 5000 ) // correct way is >=
       puts( "Sales are greater than or equal to $5000" ); // semicolon missing
   else
       puts( "Sales are less than $5000 "); // " and ; missing

---------

Ans b)

Note: In this code there is one syntax error in while loop there is also one logic error product should be equal to 1 inorder to do product 1 to 10

   int x = 1, product = 1;
   while ( x <= 10 ) { // no need of semicolon
       product *= x;
       ++x;
   }

---------------

Ans c)

while ( x <= 100 ){ // curly braces and W should be small
       total =+ x;
       ++x;
   }

-------------

Ans d)

   while ( y < 10 ) {
       printf( "%d\n", y );
       y++; // y should be incremented
   }
