#include void oddeven(int num); void posneg(int num); void fact(int num); int main(){ int number; char choice; do{ printf('A. Find Odd or EvennB. Find Positive or NegativenC. Find the Factorial valuenD.Exit'); printf('nnEnter your choice: '); scanf(' %c', &choice); if( choice != 'D' ){ printf('Enter a number: '); scanf(' %d', &number); } switch(choice){ case 'A': oddeven(number); break; case 'B': posneg(number); break; case 'C': fact(number); break; case 'D': printf('nExiting programn'); break; } }while( choice != 'D' ); return 0; } void oddeven(int num){ if( num % 2 == 0 ){ printf('nn================n%d is even numbern================nn', num); }else{ printf('nn================n%d is odd numbern================nn', num); } } void posneg(int num){ if( num >= 0 ){ printf('nn================n%d is positive numbern================nn', num); }else{ printf('nn================n%d is negative numbern================nn', num); } } void fact(int num){ int i = 0, factorial = 1; for( i = 1; i <= num; i++){ factorial *= i; } printf('nn================nFactorial of %d = %dn================nn', num, factorial); } The output of above program is A. Find Odd or Even B. Find Positive or Negative C. Find the Factorial value D.Exit Enter your choice: A Enter a number: 5 ================ 5 is odd number ================ A. Find Odd or Even B. Find Positive or Negative C. Find the Factorial value D.Exit Enter your choice: B Enter a number: 5 ================ 5 is positive number ================ A. Find Odd or Even B. Find Positive or Negative C. Find the Factorial value D.Exit Enter your choice: C Enter a number: 5 ================ Factorial of 5 = 120 ================ A. Find Odd or Even B. Find Positive or Negative C. Find the Factorial value D.Exit Enter your choice: D Exiting program
