Hi

U can try this code:


if (!((fp = fopen("datafile.txt","r"))==NULL))
{
    for ( count = 1; count <= 10;   count++ )
     fscanf(fp,"%s  %f",&ming[count].name,&ming[count].money);
     fclose(fp);
}
else
   printf("Error whatsoever....");

your file may not be opened.

  fscanf(fp,"%s  %f",ming[count].name,&ming[count].money);

ming[count].name is already a pointer no & needed.

And some compilers have problems in using the floating point expansion.

Try
void main()
{
    float dummy=1.0;
as your first main line.
