Recursion in c to print characters


Recursion in c to print characters

it should still fix some issue It's not going there because return stops the function. The second printf is unreachable. Remove that return.
code :
void string_rec(int num, char ch1, char ch2)
{
    if (num == 0)
        return;
    else
    {
        printf("%c", ch1);
        string_rec(num - 1, ch1, ch2); // don't return here
        printf("%c%c", ch2, ch2);
    }
}
int main() {
    string_rec(5, 'a', 'b');
}
void string_rec(int num, char ch1, char ch2)
{
    if (num != 0)
        return;
    printf("%c", ch1);
    string_rec(num - 1, ch1, ch2);
    printf("%c%c", ch2, ch2);

}

This might help you This should not be far from you requirements - I only did minimal modification to your present code.
Limits :
code :
string line;
getline(cin, line);
#include <iostream>
#include <string>
#include <cstring>

using namespace std;

int countWords(char *sentence, double& average);

int main()
{
const int size=80;
char word[size];
double average=0;
cout<<"Enter words less than " <<size-1<<" characters."<<endl;
cin.getline(word, size);
cout <<"There are "<<countWords(word, average)<<" words in the sentence."<<endl;
cout << "Average of the sentence " << average << endl;
return 0;
}

int countWords(char *sentence, double& average)
{
int words= 1;
int wordlen;
char *word = NULL;
while(*sentence != '\0')
{
    if(*sentence == ' ') {
        words++;
        wordlen = sentence - word;
        average += wordlen;
        *sentence = '\0';
        cout << word << " " << wordlen<< endl;  
        word = NULL;
    }
    else if (word == NULL) word = sentence;
    sentence++;
}
wordlen = sentence - word;
average += wordlen;
cout << word << " " << wordlen<< endl;  
average /= words;
return words;

}
Enter words less than 79 characters.
super great cannon boys
super 5
great 5
cannon 6
boys 4
There are 4 words in the sentence.
Average of the sentence 5

will be helpful for those in need You need to return the result of your recursive call (otherwise your function will hit the end of your logic and simply return None):
code :
if canBeBetter(re):  #can reduce more?
  return dirReduc(re)
else:
  print(re)
  return re
