Few sample programs

================

1)Print number of parenthis combinations.

#include <stdio.h>

#define MAX_OUTPUT_SIZE 200

#define MAX_PARENT      5

 

void _printParenthesis(int pos, int n, int open, int close);

void printParenthesis(int n)

{

    if (n > 0)

        _printParenthesis(0, n, 0, 0);

    return;

}

 

void _printParenthesis(int pos, int n, int open, int close)

{

    static char str[MAX_OUTPUT_SIZE];

 

    if (close == n) {

        printf("%s \n", str);

        return;

    }

    else {

        if (open > close) {

            str[pos] = '}';

            _printParenthesis(pos + 1, n, open, close + 1);

        }

 

        if (open < n) {

            str[pos] = '{';

            _printParenthesis(pos + 1, n, open + 1, close);

        }

    }

}

int main()

{

    int n = MAX_PARENT;

    printParenthesis(n);

    getchar();

    return 0;

}
