How to write programme for 'M' for loops dynamically

Hi spp,

Sorry but your problem is not clear to me. Below is my trial of what I understood from the problem specified in above post.

package myjava;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class MTimesForLoop {
    public static void main(String[] args) throws IOException{
                BufferedReader bin = new BufferedReader(new InputStreamReader(System.in));
                int M= Integer.parseInt(bin.readLine());
                for(int i=0;i<M;i++){
                        System.out.println(i+" loop out of "+M+" specified loops");
                        //put anything that you want to make to execute 'M' times
 
                }
    }
}

Output:

3
0 loop out of 3 specified loops
1 loop out of 3 specified loops
2 loop out of 3 specified loops

Please add exactly what kind of stuff you are looking for? Also, feel free to correct if anything wrong done.

Thanks !

HI sookie
I think u dont understand my problem.what problem I am facing is for any value of 'M' total 'M' for loops will execute.
example:
let i want to print "Hello world" and M=3
then the code will be
for(i=0;i<m;i++)
{
for(j=0;j<m;j++)
{
for(k=0;k<m;k++)
{
printf("Hello world");
}
}
}
for M=4
total 4 for loops will be used ie
for(i=0;i<m;i++)
{
for(j=0;j<m;j++)
{
for(k=0;k<m;k++)
{
for(l=0;l<m;l++)
{
printf("Hello world");
}
}
}
}

Below is my code for the given problem statement solved using recursion.

#include "stdio.h"

void function(int m, int n, int* loopIndexes) {
  printf("Hello\n");
}


void mNumberOfLoops(int m, int n, int currentLoop, int* loopIndexes) {
  int i = 0;

  if(currentLoop != m) {
    for(i = 0; i < n; i++) {
      loopIndexes[currentLoop] = i;
      mNumberOfLoops(m, n, currentLoop + 1, loopIndexes);
    }
  } else {
    function(m, n, loopIndexes);
  }
}


int main() {
  int m = 0, n = 0;
  int *loopIndexes = NULL;
  int i = 0;

  scanf("%d%d", &m, &n);
  if((m < 1) || (n < 1)) {
    printf("Invalid input\n");
    return 0;
  }

  loopIndexes = (int*)malloc(sizeof(int)*m);
  for(i = 0; i < m; i++) {
    loopIndexes[i] = 0;
  }

  mNumberOfLoops(m, n, 0, loopIndexes);

  return 0;
}

Let me know if you have some query.

@spp Oh so you were talking about "nested for loops -m times". Dude if you simply want to print("Hello") M[sup]M[/sup] times then why so much complications with for loops? Are you planning to do something else also in each of your "nested for loop" everytime ?

yah dude.m writing a programme to find the basic feasible solutionof a given system of equation.
for that i have to select a m*m matrix from a given m*n matrix and for that i need the use of 'nested for loops'.
thanks dude for showing interest on this problem.
