2. C program to check whether a person is eligible to vote using IF statement #include < stdio.h > int main() { int age; printf ("Enter your age: "); scanf ("%d", &age); if (age >= 18) { printf ("You are eligible to vote.\n"); } else { printf ("You are not eligible to vote.\n"); } return 0; }

3. C program to find whether the given number is odd or even using IF statement #include < stdio.h > int main() { int number; printf ("Enter a number: "); scanf ("%d", &number); if (number % 2 == 0) { printf ("The number is even.\n"); } else { printf ("The number is odd.\n"); } return 0; }

4. C program to find the largest of two numbers using IF ELSE statement #include < stdio.h > int main() { int num1, num2; printf ("Enter two numbers: "); scanf ("%d %d", &num1, &num2); if (num1 > num2) { printf ("The largest number is %d.\n", num1); } else { printf ("The largest number is %d.\n", num2); } return 0; }

5. C program to find the greatest of three numbers using if else if statements #include < stdio.h > int main() { int num1, num2, num3; printf ("Enter three numbers: "); scanf ("%d %d %d", &num1, &num2, &num3); if (num1 >= num2 && num1 >= num3) { printf ("The greatest number is %d\n", num1); } else if (num2 >= num1 && num2 >= num3) { printf ("The greatest number is %d\n", num2); } else { printf ("The greatest number is %d\n", num3); } return 0; }

6. C program to check whether the entered number is positive, negative or zero using IF ELSE IF statements #include < stdio.h > int main() { int number; printf ("Enter a number: "); scanf ("%d", &number); if (number > 0) { printf ("The number is positive\n"); } else if (number < 0) { printf ("The number is negative\n"); } else { printf ("The number is zero.\n"); } return 0; }

7. C program to display the corresponding day of the week using SWITCH CASE statement #include < stdio.h > int main() { int day; printf ("Enter a number (1-7) for the day of the week: "); scanf ("%d", &day); switch (day) { case 1: printf ("Monday\n"); break; case 2: printf ("Tuesday\n"); break; case 3: printf ("Wednesday\n"); break;

8. case 4: printf ("Thursday\n"); break; case 5: printf ("Friday\n"); break; case 6: printf ("Saturday\n"); break; case 7: printf ("Sunday\n"); break; default: printf ("Invalid input! Please enter a number between 1 and 7\n"); } return 0; }

9. C program to implement a scientific calculator using SWITCH CASE statement #include < stdio.h > #include < math.h > int main() { int choice; double num1, num2, result; printf ("Scientific Calculator\n"); printf ("1. Addition\n"); printf ("2. Subtraction\n"); printf ("3. Multiplication\n"); printf ("4. Division\n"); printf ("5. Power ( x^y )\n"); printf ("6. Square Root\n"); printf ("Enter your choice (1-6): "); scanf ("%d", &choice); switch (choice) { case 1: printf ("Enter two numbers: "); scanf ("% lf % lf ", &num1, &num2); result = num1 + num2; printf ("Result: %.2lf\n", result); break;

10. case 2: printf ("Enter two numbers: "); scanf ("% lf % lf ", &num1, &num2); result = num1 - num2; printf ("Result: %.2lf\n", result); break; case 3: printf ("Enter two numbers: "); scanf ("% lf % lf ", &num1, &num2); result = num1 * num2; printf ("Result: %.2lf\n", result); break; case 4: printf ("Enter two numbers: "); scanf ("% lf % lf ", &num1, &num2); if (num2 != 0) { result = num1 / num2; printf ("Result: %.2lf\n", result); } else { printf ("Error: Division by zero!\n"); } break;

11. case 5: printf ("Enter base and exponent: "); scanf ("% lf % lf ", &num1, &num2); result = pow(num1, num2); printf ("Result: %.2lf\n", result); break; case 6: printf ("Enter a number: "); scanf ("% lf ", &num1); if (num1 >= 0) { result = sqrt(num1); printf ("Result: %.2lf\n", result); } else { printf ("Error: Cannot calculate the square root of a negative number!\n"); } break; default: printf ("Invalid choice! Please enter a number between 1 and 6.\n"); } return 0; }
