    Question keeping values of scanf

    i was wondering if it is possible to have a scanf in a for loop and keep each value the user inputs? how can i store each value the user inputs?
    i need to keep each value because the program takes input from the user and takes the derivative of the polynomial. now i am using a for loop but i don't know how to keep each value for the scanf. am i approaching this the wrong way? what can i do? here is the part of the code. (it repeats for as many values of "a" there is).
    for(b = 0; b <= a; b++)
        printf("Enter coefficient for x^%d: ", b);
        scanf("%d", &c);

    Make c an array

    scanf( "%d", &c[b] );
    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.
