Draw a flow chart and write its corresponding C program to convert an octal number to its equivalent decimal number. Do it from book… 2. Write an algorithm and its corresponding C program to illustrate an ATM money withdrawl operation from user’s savings’ account. Solution: This C Program performs ATM transaction. The types of ATM transaction are 1) Balance checking 2) Cash withdrawal 3) Cash deposition. Here is C Program to display the ATM transaction: 1. #include <stdio.h> 2. 3. unsigned long amount=1000, deposit, withdraw; 4. int choice, pin, k; 5. char transaction ='y'; 6. 7. void main() 8. { 9. while (pin != 1520) 10. { 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.

Q.4. Write a C program to separate even and odd numbers of an array and put them in two arrays. Solution: This C Program puts even & odd elements of an array in 2 separate arrays. The program first finds the odd and even elements of the array. Then the odd elements of an array are stored in one array and even elements of an array are stored in another array. 1. #include <stdio.h> 2. 3. void main() 4. { 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25.

Q.3. Write a C program to determine a given matrix is a sparse matrix. Solution: This C Program determines the given matrix is a sparse matrix. Sparse matrix is a matrix with the majority of its elements equal to zero. This program accepts matrix and checks whether the given matrix is a sparse matrix. 1. #include <stdio.h> 2. 3. void main () 4. { 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
