    [warning] strcpy makes pointer from integer without a cast

    Hi! I'm new to CBoard and to programming so please bear with me. Imma noob.

    Suppose I have this structure for Costumer Account:

    Code:
    typedef struct
    {
          char account[6];
          int balance;
    }COSACC;
    And I have to compare the balance from something inputted.

    Code:
    printf("\n\nEnter New Balance: ");
    scanf("%d", &ab);
    strcpy(y[i].balance, ab);
    How do I do something like that as to not get a warning? Thanks so much!

    Could you post more of your code please?
    What is the y and ab declared as?
    You get this warning because you do not pass the arguments as you should.You have to keep in mind the prototype of strcpy strcpy - C++ Reference.There is also an example there

    Since balance is an int not a C-string you would do something like:
    Code:
    y[i].balance = ab;
    // or without the intermediate variable.
    scanf("%d", &y[i].balance);
    The strcpy() function only works with nul terminated character strings.

    Just get rid of strcpy() altogether and compare the two integers in your code.

    They aren't strings, so all you probably wanted was:
    Code:
    y[i].balance = ab;
    However, if that's all you're doing, then you don't need the variable ab at all. You could just read straight into the desired location, in two lines, like this:
    Code:
    printf("\n\nEnter New Balance: ");
    scanf("%d", &y[i].balance);

    Thank you! This was all I needed to do.

    Sorry it took me this long to reply. I'm swamped with projects and darn tests. Thanks for all your help, guys!
