Answer Posted / jane
#include<stdio.h>
void print_1_to_100(int n);
void print_100_to_1(int n);
int main()
{
print_1_to_100(1);
return 0;
}
void print_1_to_100(int n)
{
printf("%d\t",n);
(n/100)? print_100_to_1(n) :print_1_to_100(n+1);
}
void print_100_to_1(int n)
{
printf("%d\t",n);
(n-1)? print_100_to_1(n-1) :1;
return;
}
