Need help in my C language assignment... all I need to do is
1.Use recursion instead
2. NO LOOPS ALLOWED
Output _______________________________________
What number shall I start with? 16 sequence: 16 8 4 2 1 length: 5 largest: 16 For start values from 1 to 16: longest: 9 28 14 7 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 length: 20 containing largest: 15 46 23 70 35 106 53 160 80 40 20 10 5 16 8 4 2 1 largest: 160

I'll write the another functions after I get an idea on what to do
#include<stdio.h>
int next(int n)
{
int x = n;
if(x%2 == 0)
{
x = x/2;
return x;
}
else
{
x = 3 * x + 1;
return x;
}
}
void PrintSequence(int n)
{
int x = n;
if(x <=1)
{
printf("1");
return 0;
}
printf("%i ",x);
x = next(x);
//recursive calling of PrintSequence
//This will print the number every which will
return by next(x)
PrintSequence(x);
}
int length(int n)
{
static int count = 1;
int x = n;
if(x<=1)
{
return 0;
}
x = next(x);
count++;
//recursive calling of function length()
length(x);
return count;
}
int largest(int n)
{
//static varibale not intialized again once it
executed
static int max = 0;
int x = n;
if(x<=1)
{
return 0;
}
if(max<=x)
{
max = x;
}
x = next(x);
//recursive calling of function largest
largest(x);
return max;
}
int main()
{
int n,count=0,max = 0;
printf("Enter n value: ");
scanf("%d",&n);
printf("Sequence: ");
PrintSequence(n);
count = length(n);
printf("\nLength: %d\n",count);
max = largest(n);
printf("Largest: %d",max);
return 0;
}

the coding language is just the basic c language and here is my first attempt at this problem my problem is that if the user inputs a number that is equal to a number that has been entered previously the code will never end until the user enters a number that is bigger than any other number previously entered any help will be helpful Write a program to read-in a sequence of integers from the keyboard using scanf(). Your program...
My C program is supposed to make a random key the same length of clear_text string and then use the random key to encrypt clear_text, but I can’t get it to work.

Programming language: C NOT c++ Problem 2 (20 points) Both the for loop and the do-while loop can be transformed into a simple while loop. For each of the following examples a) and b), write equivalent code using a while loop instead. double rand_double)( double ret - (double)rand(); return ret/ (RAND MAX 1); int factorial (int n) int for i, ret =1; (i=2; i <= ret *= 1; n; i++) int sample_geometric_rv(double p)l double q return ret; int ne; do...
any help! my program not working , there is an error but cannot solve it i did this program after editing a previous program and i tried to follow the following ; 1.

Please I need help in C language, I am trying to modify the code per the below instructions, but I am getting errors. Can't fgure it out. The attempted code modification and data file is privided below, after the instructions. Thank you. Instructions: 1. First, add a function named printMsg that displays a message, a greeting, or an introduction to the program for the user. Add a statement that calls that function from the main function when your program starts....
