Having a difficult time running this small piece of code.  Not sure what is going on.  Expect to print an int, a char, a string and another string.  First string prints but second hangs.  I realize this is a strange way to do this but I want to read character by cahracter.

#include <stdio.h>

void vGetString(char cBuff[], int iMax);
char str[3][41];
char char1;
int int1;
void main()
{

   printf("     enter int       : ");
   scanf("%d", &int1);
   printf("     char1           : ");
   while(getchar() != '\n');
   scanf("%c", &char1);
   printf("Char1 is[%c]: ", char1);
   printf("\n   title1          : ");
   vGetString(str[0], 40);
   printf("\n[%s] ", str[0]);
   printf("\n   title2          : ");
   vGetString(str[1], 40);
   printf("\n[%s] ", str[1]);
}

/****************************************************
void vGetString(char cBuff[], int iMax)
{
   char cTemp[256];
   int idx=0;
   while (getchar() != '\n');
   while ((cTemp[idx] = (char)getchar()) != '\n')
   {
      ++idx;
   }
   if (idx > iMax)
   {
     cTemp[iMax] = '\0';
   }
   else
   {
     cTemp[idx] = '\0';
   }
   strcpy(cBuff, cTemp);
}
