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");
}
