    void func1( int);
    void func2( int );
    int main()
     void (*f[2])(int) = { func1, func2 };
     int choice;
     printf("Enter an input:");
     scanf("%d", &choice );
     (*f[ choice ])(choice);
          return 0;
    void func1( int num)
     printf("you entered %d.So function 1 was called\n", num);
    void func2( int num)
     printf("You enterd %d.SO function2 was vcalled", num );

    Actually, you can do

    f[choice]( choice );
