  1. What will be the output of the program?

    #include 
 int main() 
 {  
     int a = 500, b = 100, c;      
     if(!a >= 400)   
         b = 300;   
  c = 200;    
   printf("b = %d c = %d\n", b, c);         
   return 0; 
}

    2. A.

    b = 300 c = 200
    B.

    Answer : Option D

    Explanation :

    Initially variables a = 500, b = 100 and c is not assigned.

    Step 1: if(!a >= 400)
    Step 2: if(!500 >= 400)
    Step 3: if(0 >= 400)
    Step 4: if(FALSE) Hence the if condition is failed.
    Step 5: So, variable c is assigned to a value '200'.
    Step 6: printf("b = %d c = %d\n", b, c); It prints value of b and c.
    Hence the output is "b = 100 c = 200"
