    Floating number error

    can anyone find the mistake in the following code:

    int degree;
    float fun01coff[100];
    float fun02coff[100];
    void main()
    printf(" enter the degree of equation\n\n");
    scanf("\n%d", &degree);
    printf(" enter the coeffiecients\n\n");
    int i =0;
    for(i =0; i<= degree; i++)
    scanf("\n %d", &fun01coff[i]);
    int deg = degree;
    float res = 0.0;
    for( i = 0; i<= deg; i++)
    printf("\n printing value of i = %d",i);
    res = res + (float)(fun01coff[i]*(pow(0,deg-i)));
    printf(" \n\n answer = %f", res);

    i wanted to find the value of polynomial for some value of x such as x = 0

    Well the first mistake is that you've been here for nearly a year, but you're still posting code without using [code][/code] tags.

    So consider your post as being ignored for the moment.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper

    Also, just exactly why do you think that there's any mistake in your code?

    IOW, what are the symptoms that lead you to believe that there's a mistake? We cannot read your mind and we don't have time to play stupid guessing games.

    This line is wrong:
     scanf("\n %d", &fun01coff[i]);
    You've declared fun01coff as float. You shouldn't be using %d to read into it. I'll leave it to you to figure out what the correct format string should be, as a homework assignment :).
