Help with code for encoding and decoding letters

Hi I'm pretty new to programming and I need some help getting this code to work. Its supposed to offer the user a choice to either encode letters or decode them. Their supposed to enter 1 to encode, where they enter a number of random letters "khgdhf" and the result will be "1k2h1g1d1f" or 2 to decode where they enter the opposite "2h4g1t" and it displays "hhggggt". After I enter the choice nothing happens? Any help would be appreciated.

Code:

# include <stdio.h>
# include <ctype.h>
void		encode(void);
void		decode(void);

int main(void)
{
	int choice;

	printf("Type 1 to encode, 2 to decode:");
	scanf("%d", &choice);

	if (choice==1)
	
		encode();
	
	if (choice==2)
	
		decode();
	

}
void encode(void)

{
	char ch, nextch;
	int count;

	do
	{
		scanf("%c", &ch);
	}
	while (ch!='*');
	printf("%c",ch);
	scanf("%c", &ch);
	do
	{
		count=1;
		nextch=ch;
		while (nextch==ch)
		{
			count=count+1;
			scanf("%c", &nextch);
		}
		if (count>1)
		{
			printf("%d%c", count, ch);
		}
		else
		{
	printf("%c", ch);
}
ch=nextch;
}
while (ch!='*');
printf("%c",ch);
printf("\n\n");
}

void decode(void)
{
	char ch;
	int count, i;

	do
	{
		scanf("%c", &ch);
	}
	while(ch!='*');
	printf("%c",ch);

	scanf("%c", &ch);
	do
	{
		if (isdigit(ch))
		{
			count=ch-'0';
			scanf("%c", &ch);
			for(i=0;i<count;++i)
				printf("%c",ch);
		}
		else
		{
			printf("%c",ch);
		}
		scanf("%c", &ch);
	}
	while(ch!='*');
	printf("%c",ch);
	printf("\n\n");
}

Nevermind I got it.
