By using #pragma pack(1) we can reduce the size of structure. 

Code
  1. #pragma pack(1)
    2. 

  2.  
    3. 

  3. struct num {
    4. 

  4.   char ch;
    5. 

  5.   int i;
    6. 

  6.   char s;
    7. 

  7. } n1;
    8. 

  8.  
    9. 

  9. printf("Size of num structure is %d ", sizeof(n1));
    10.
