Question

Help! I need to write a program in C that takes 2 command line arguments that are numeric (height & width). The program needs to print a block of random text letters with the specified dimensions (width characters per line, height lines). The program has to use a subroutine that takes the 2 parameters, allocates a char buffer, fills it randomly as appropriate, and returns a pointer to that buffer (a char*). The main method should print this buffer and free the allocated memory. *note: I am on a Linux vm therefore i am using the bash gcc compiler with gedit. Also, this is C not C++. Help!

Explanation / Answer

// C program:

#include <stdio.h>
#include <stdlib.h>

char** GenerateRandomText(int height, int width);

int main(int argc, char *argv[])
{
   int height;
   int weight;
  
   int i,j;
   height = atoi(argv[1]);
weight=atoi(argv[2]);
   /*receiving the buffer,which contains randomly generated characters*/
   char **RandomText = (char **)malloc(sizeof(char *) * (height*weight));
   RandomText=GenerateRandomText(height,weight);
   //printing contents of buffer
   printf(" Randomly generated contents: ");
   for(i=0;i<height;i++)
   {
       printf(" %s",*(RandomText + i));
   }
   free(RandomText);
   return 0;
}

char** GenerateRandomText(int height, int width)
{
   int i,j;
   //buffer to store randomly generated characters
   char buffer[height][width];
  
   for(i=0;i<height;i++)
   {
       for(i=0;i<height;i++)
       {
           //generating random charcters
           char randomletter = 'A' + (rand() % 26);
           //storing random chars in a buffer
           buffer[i][j]=randomletter;
       }
   }
   //returning buffer to main function
   return buffer;
}
