Hi, I'm trying to read data from file to structure members, the code seems to work but when I print out strings, the first line output garbage and the rest is according to what the program should do. why does the first line output garbage? also the first line was not intended to be print out. This is my output:
Enter the file name: in.txt
,-842150451
A,10
B,12
C,60
D,120
tutorY
Press any key to continue . . .
