    Why does it skip a scanf()?

    #include <stdio.h>
    #include <math.h>
    main() {
            int mon;
            double price, finance, rate , mpay, tpay, r;
            printf("Enter the price of the house (in $):");
            scanf("%.2f", &price);
            if (price<0)
                    printf("Please enter positive price\n");
            else {
            printf("Enter the amount to be financed (in $):");
            scanf("%.2f", &finance);
            if ((finance<0)||(finance>0.8*price))
                    printf("Please enter appropriate values for finance\n");
            else {
            printf("Enter the annual percentage rate (in percent):");
            scanf("%.2f", &rate);
            if (rate<=0)
                    printf("Please enter a positive rate\n");
            else {
            printf("Enter the term in number of months:");
            scanf("%d", &mon);
            if ((mon<=0)||(mon%12!=0)||(mon>480))
                    printf("Please enter appropriate value for number of months\n");
            else {
                    printf("\nThe price of the house is: %.2f $\n", price);
                    printf("The amount to be financed is: %.2f $\n", finance);
                    printf("The annual percentage rate is: %.2f percent\n", rate);
                    printf("Your monthly payment is : %.2f $\n", mpay);
                    printf("Your total payment will be: %.2f $\n", tpay);

    When i run this code, it asks for the first price, and after that, it skips to the the message "Please enter correct rate". like it doesnt even go to the second scanning part where it asks for the finance. Please Help

    Please use code tags.

    Check the position of your braces.

    Where is the matching closing brace for the first "else" opening brace ?

    And this program is C, not C++, so it's in the wrong forum.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
