The output of the program would be:
0 200
This is because the variable a has a value of '300', which is not greater than or equal to '400', so the statement b = 300 is not executed. Therefore, the value of b remains uninitialized and contains an unspecified value. The statement c = 200 is executed, so the variable c has a value of 200.
When the printf statement is executed, the value of b is printed, which is uninitialized and therefore has an unspecified value (in this case, 0), followed by the value of c, which is '200'. Therefore, the output is '0 200'.
