    File Handling problem, please help

    I have a data file, data.txt
    Code:
    1     0.011070     0.5100     0.4900     1.0211
    	9	2
    	11	19	8    7
    2     0.021373     0.1000     0.0870     1.1332
    	8	13
    	6	14	5    9
    and so on..

    The first no. is n (going 1,2,... till 100).
    Now, I am having a nightmare of a time in making a C code for reading this data.
    How can I make a C code to read data.txt, such that I can make the following matrices :

    a[1][1]=0.011070, a[1][2]=0.5100, a[1][3]=0.4900, a[1][4]=1.0211
    b[1][1]=9, b[1][2]=2
    c[1][1]=11, c[1][2]=19, c[1][3]=8, c[1][4]=7

    Similarly, for n=2 (4th, 5th & 6th rows)
    a[2][1]=0.021373, a[2][2]=0.1000, a[2][3]=0.0870, a[2][4]=1.1332
    b[2][1]=8, b[2][2]=13
    c[2][1]=6, c[2][2]=14, c[2][3]=5, c[2][4]=9

    and I go upto n=100.

    As is clear, I want matrix a to be float, and b and c as int.

    *The no. of columns of array a,b and c are same for all n.

    PLEASE KINDLY HELP SOON, AM BADLY STUCK.
    Regards
    Alice
