Question

C Programming

1. Provide an equivalent of the java class in C

class Example
{

public static int[][] question4(int n)
{
int[][] result = new int [n][n];
for(int i=1; i<=n; i+=1) for (int j=1; j<=n; j+=1) result[i][j] = (i*n)+j;
return result;
}

public static void main(String[] args)
{
int[][] my array = question4(4);
}


}

2. Rewrite the following function using no loops, and only tail call recursion

int min  (int n, int[] input)
{
     int i;
     int result;
     for (result = input[0], i = 0; i < n; i += 1)
     {
         if (result > input[i]) result = input[i];
     }
     return result;
}

Answer 1

#include <stdio.h>

int **question4(int n)
{
    int **result;
    
    for(int i=1; i<=n; i+=1)
    {
        for (int j=1; j<=n; j+=1) 
        {
            result[i][j] = (i*n)+j;
        }
    }
    
    return result;
}

int main()
{
   int **my_arrayquestion4(4);

    return 0;
}

2.

int min(int n, int[] input)
{
    
    int result;

    if(n==1)
        return input[0];

    else {
        result=min(n-1,input);

        if(result<input[n-1])
            return result;
        else
            return input[n-1];
    }
}
