Hello,
I am finding it difficult to determine the length of the columns in a
2D unsigned short pointer array. I have done memory allocation correctly as far as I know. and can print them correctly.
plz see the following code segment:
int number_of_array_index_required_for_pointer_abc=3;
char A[3][16];
strcpy(A[0],"Hello");
strcpy(A[1],"World");
strcpy(A[2],"Tumanicko");
cout<<number_of_array_index_required_for_pointer_abc*sizeof(unsigned short)<<endl;
unsigned short ** pqr=(unsigned short **)malloc(number_of_array_index_required_for_pointer_abc*sizeof(unsigned short));
for(int i=0;i<number_of_array_index_required_for_pointer_abc;i++)
{
int ajira = strlen(A[i])*sizeof(unsigned short);
cout<<i<<" = "<<ajira<<endl;
pqr[i]=(unsigned short *)malloc(ajira);
cout<<"alocated pqr[i]= "<<sizeof pqr<<endl;
int j=0;
for(j=0;j<strlen(A[i]);j++)
{
pqr[i][j]=(unsigned short)A[i][j];
}
pqr[i][j]='\0';
}
for(int i=0;i<number_of_array_index_required_for_pointer_abc;i++)
{
//ln= (sizeof pqr[i])/(sizeof pqr[0]);
//cout<<"Size of pqr["<<i<<"]= "<<ln<<endl;
// I want to know the size of the columns i.e. pqr[i]'s length instead of finding '\0'
for(int k=0;(char)pqr[i][k]!='\0';k++)
cout<<(char)pqr[i][k];
cout<<endl;
}
