C program timeout

[PreciouLonon]

Here is the program I have at the moment

<br /> int main (void) //Main program function<br /> {<br /> <br /> char *stores[3] = {"Del Mar", "Encinitas", "La Jolla"};<br /> float taxPercent[3]={7.25, 7.5, 7.75}; // Tax variable for all three stores<br /> float price; //float variable for the price<br /> <br /> do {<br /> printf("ttKudler Fine Foods Tax Calculatornn"); // prints header<br /> printf("Please enter the amount of your purchase: ");<br /> scanf("%f", &#038;price);<br /> <br /> <span style="color:#0000FF"> if (0.0 > price) {<br /> printf("Purchase amount must be positiven");<br /> }<br /> } while(price < 0.0);</span><br /> <br /> float taxTotal[3] = {price * (taxPercent[0]/100), price * (taxPercent[1]/100), price * (taxPercent[2]/100)}; //calculates the total for each store<br /> <br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[0], taxPercent[0], taxTotal[0]); //prints tax information for Del Mar<br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[1], taxPercent[1], taxTotal[1]); //prints tax information for Encinitas<br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[2], taxPercent[2], taxTotal[2]); //prints tax information for La Jolla<br /> <br /> getch(); // waits for user to press a key<br /> <br /> return 0; // return of int main()<br /> <br /> } // end main<br />

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

<br /> int main (void) //Main program function<br /> {<br /> <br /> char    *stores[3] = {"Del Mar", "Encinitas", "La Jolla"};<br /> float taxPercent[3]={7.25, 7.5, 7.75}; // Tax variable for all three stores<br /> float price; //float variable for the price<br /> <br /> do {<br /> printf("ttKudler Fine Foods Tax Calculatornn");  // prints header<br /> printf("Please enter the amount of your purchase: ");<br /> scanf("%f", &#038;price);<br /> <br /> <span style="color:#0000FF">  if (0.0 > price) {<br /> printf("Purchase amount must be positiven");<br /> }<br /> } while(price < 0.0);</span><br /> <br /> float taxTotal[3] = {price * (taxPercent[0]/100), price * (taxPercent[1]/100), price * (taxPercent[2]/100)}; //calculates the total for each store<br /> <br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[0], taxPercent[0], taxTotal[0]); //prints tax information for Del Mar<br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[1], taxPercent[1], taxTotal[1]); //prints tax information for Encinitas<br /> printf("nThe tax for the %s store at %.2f%% is %.2f", stores[2], taxPercent[2], taxTotal[2]); //prints tax information for La Jolla<br /> <br /> getch(); // waits for user to press a key<br /> <br /> return 0; // return of int main()<br /> <br /> } // end main<br />

I want to add a timeout function on the if statement in blue and then clear the screen with system(“cls”); Any help on how to create the timeout function?

I am using Dev C++ compiler and what I am trying to do is asking a user to enter a purchase amount, if it is negative I am giving them a message it must be positive then after about 10 second clear the screen so they can reenter a proper purchase price.

You use can sleep function for prompting to require amount of time.

In condition you add the sleep(10).

It will wait for 10 seconds, then do the require stuffs
