You asked for C code, you were writing C++ code. Notice how the C code is all far simpler and more elegant anyway.

A slightly changed version which doesn't use stdin:

Code:
#include <stdio.h>

int main(void) {
        char buf[512];
        unsigned int v;
        FILE *fp=fopen("file.dat", "r");
        if(fp == NULL) return(1);

        while(fgets(buf, 512, fp))
        {
                if(sscanf(buf, "0x1%04x", &v) != 1)
                {
                        fprintf(stderr, "Unable to parse line '%s'\n", buf);
                        continue;
                }

                printf("Got hex value %x = decimal value %d\n", v, v);
        }
}

Dear corona and Chacko,
Thanks for the help.
Corona, I could see the simplicity of the C-programming, but I am more used to of c++ programming.

I have one more question, if in the same data.txt file, I would like to read the second column data format like e2e2e2fd
How that can be achieved in the same code [1]

thanks
emily

    getline(datafile,data16,'\n');
    getline(datafile,data32,'\n');
    ssData16 << data16;
    ssData16 >> data16;
    ssData32 << data32;
    ssData32 >> data32;
    data16.erase(0,3);
    data32.erase(0,3);
    cout<<"data : " << data16 <<", "<< data32<< endl;

Very minor change.

Code:
#include <stdio.h>

int main(void) {
        char buf[512];
        unsigned int v, q;
        FILE *fp=fopen("file.dat", "r");
        if(fp == NULL) return(1);

        while(fgets(buf, 512, fp))
        {
                if(sscanf(buf, "0x1%04x 0x3%04x", &v, &q) != 2)
                {
                        fprintf(stderr, "Unable to parse line '%s'\n", buf);
                        continue;
                }

                q <<= 8;  q |= 0xfd;

                printf("Got values %x(%d), %x(%d)\n", v, v, q, q);
        }
}

Thank you Corona,
But unfortunately, I would prefer to work with c++ code, as I feel more comfortable with it.
Can you please suggest the modifications needed in my script which is given in last thread.

Thank you again,
emily

In your OP, you said that you need to combine two lines, which contains 20 bit hex, and form a 32 bit value.

Now you are saying that you need to combine two column.
In e2e2e2fd, what is the third e2 pair? Is it the MSB of hex you read from file or the LSB?

Please make your actual requirement clear.

Hello,
No I do not need to combine two different columns.
Task-01 is already achieved using [1] to read the Blue data at a time 00001E00.
But I also need to read the data from second column (only second column) like the red entries at time E2E2E2FD (omitting the 0x3)

thanks
emily
