How do you Write a Program using Recursive Function that prints a list of numbers from 100 down to 1 in C?

On entry to the function it increments a static variable. If a variable has a value below 100, it calls itself again. It then prints the value of the variable, decrements it and returns

How do you Write a Program using Recursive Function that prints a list of numbers from 100 down to 1 in C?
#include%26lt;stdio.h%26gt;


#include%26lt;conio.h%26gt;





void printnum(int num)


{


printf("%d",num);





if(num%26gt;1)


printnum(num-1);


}





int main()


{


printnum(100);





getch();


return 0;


}

{


printf("%d",num);


if (n%26gt;1)


{


fun(num-1);


}


}


main()


{


fun(100);


}
Reply:void printnum(int num, int hasnextline)


{


if (num %26gt; 0)


{


printf("%d", num);


if (hasnextline)


{


printf("\n");


}


printnum(num - 1, hasnextline);


}


return;


}





That should do it... But I haven't tried this one... Recursive functions are rather difficult to create, since this one is a bit basic, it'll be a bit easy to understand...





I hope this code works... (^^,)





BTW, int hasnextline is the variable which tells the function if you need to print a next line character after every number... Which somehow adds a feature for the function...
