    while ( cnt != -1 ) {
    printf("\nEnter account number (-1 to end ):");
    scanf("%d", &act);
    if ( act == -1)
    printf("\nEnter beginning balance: ");
    scanf("%d", &balance);
    printf("\nEnter total charge: ");
    scanf("%d", &Tcharge);
    printf("\nEnter total credits: ");
    scanf("%d", &Tcredit);
    printf("\nEnter credit limit: ");
    scanf("%d", &limit);
    if ( Nbalance > limit ){
    printf("Acount: %d\n", act);
    printf("Credit limit: %d\n", limit);
    printf("Balance: %d\n",Nbalance);
    Nbalance = balance + Tcharge - Tcredit;

    1) Learn how to form correct sentences (and words). No one wants to read that butchered typing.

    2) How about you actually give a value to 'Nbalance' before you use it? That might be a good idea, huh? Nbalance has no value. Actually it does, but it's some random arbitrary number since you have fallen into one of the most basic traps for newbies: You're using a variable without initializing it. This is a "BadThing(TM)".

    Hope is the first step on the road to disappointment.

    also by the looks of it your while statement
    while ( cnt != -1 )
    should me
    while ( act != -1 )

    and just to make sure it goes in there (as quzah said) the vale of act could possibly be -1, no way to no so you should set it to 0 or some value before the while statement.

    I answered your question in a previous post, please don't start a new thread with the same question. If I'm thinking of someone else, please accept my appologies, but I'm pretty sure this is the same program.

    My best code is written with the delete key.
