Question

a. Submit this homework electronically. Name your program hw14a.c

b. Don’t do what the problem states. We’ll do something different.

c. Let the input file, hw14a.in, contain:

Boomer, Baby 1

Lady, Old 101

Ryan, Elizabeth 62

McIntyre, Osborne 84 ...

/* plus the other 4 names in the text */

d. Read in the list of names, one row at a time, using fgets()until the null pointer is reached (an address of 0), which occurs at the end of the file. The C code using fgets() will look something like:

status = fgets(line, MAX, inp);

where line is the input string, MAX is the maximum number of characters, inp

is the input file pointer, and status is a character pointer.

e. Use sscanf() to separate a line of data into a last name (string), first name

(string), and an age (integer).

f. Use sprintf() to recreate a line of output data of the format:

1 Baby Boomer

101 Old Lady

62 Elizabeth Ryan

84 McIntyre, Osborne

......

g. Then print this output line to the output file, hw14a.out, one line at a time. It should look like what is displayed in part f.

    #include <stdio.h>
    #include <conio.h>
     #include<string.h>
    
    int main()
    {
        char name[20];
        char name1[20];
        int p;
    char c[60];
    char out[40];
    FILE *f1;
    FILE *f2;
    f2 = fopen("hw14a.out","w");
    f1=fopen("hw14a.in","r");
    while(!feof(f1))
    {
    fgets(c,60,f1);
    sscanf(c,"%s %s %d ", name,name1,&p);
    name[strlen(name)-1]='';
    sprintf(out,"%d %s %s",p,name,name1);
    fprintf(f2,"%s ",out);
}
    fclose(f1);
    fclose(f2);
    getch();
   
   
    return 0;
    }
