    Question problem with gets

    hi
    i wroth this program :
    as soon as i change gets to scanf in /*/line it works properly otherwise it does not work!!
    i woner why??
    the problem is with the second gets as if it does not works
    i have to use gets because i need to read in a string instead of a word!
    #include<stdio.h>
    #include<stdlib.h>
    #include<string.h>
    typedef struct{
    char name[30];
    float mark;
    }person;

    main(){

    person m1;
    person n1;
    int flag=0,counter=0;

    puts("enter the first name");
    gets(m1.name);
    puts("enter the correspondence mark");
    flag=scanf("%f",&m1.mark);

    while (flag!=EOF){
    counter++;
    printf("enter the next name\n");
    /*/ gets(n1.name);
    printf("enter the correspondence mark\n");
    flag=scanf("%f",&n1.mark);
    if(n1.mark>m1.mark)
    m1=n1;
    }
    if(counter)
    printf("the best student is %s and his mark is %.2f",m1.name,m1.mark);
    else
    puts("you did not enter any record");
    }

    For God's sake use code tags!

    What doesn't work?

    because your previous scanf() more than likely leaves a newline character. scanf and gets have problems with each other, you should only really use one, and if you choose to use gets, use fgets() so you dont have buffer overflow. Read the faq.

    What stumon said, your compiler should warn you about gets, I know mine does. This is what it says when I try to use gets lol.
    Code:
    In function `main':
    : the `gets' function is dangerous and should not be used.

    Yea, this is what mine says:
    Code:
    In function 'main':
    : Don't f'n use that damn 'gets' function or I [the compiler] will crash your computer.
    j/k

    stumon.. i think that is what all compiler should say about gets and puts.

    And do it. But then we do have an example of that all ready (read windows)

    There's nothing wrong with puts. It simply sends a string to the standard output device with a trailing newline. There are no buffer related bugs (or any realy for that matter).

    I know I just dont like puts().

    Its just that I got used to the various fputs() and such rather then the generic puts().

    That way you know where its going anyways.

    Agreed, however, I was just was clarifying for those who aren't aware. It's best not to mislead, even if unintentional.

    Ahh Ok.. Didnt think of that.. Work is killing my brain. Hopefully I will get them to give me a compiler soon. I told them Either I will need perl or Visual C++ for this DB project Im working on.
