these are the data present in values.txt

I have to write fn1() such that for the
first time fn1() is called it should input first line,
second time its called it should input second line

can anyone help me... how should i use fseek to jump to the line i want...i can handle with fopen and fscanf..

But the major problem is Jumping to the required line

Use getline() to read a whole line, then parse that line to extract the fields of information.
