    <p>i wrote this code in class today with the teacher helping me but I'm home now and need guidance, I'm not sure what i should do next to get it to compile atleast</p> <p>the objective is to:</p> <p>create a menu enter a number(option A) dispaly the average (option B) display the highest and lowest number(option C and D) display the total of all numbers entered(option E) display the total amount of numbers entered(option F) and quit(option G)</p> <p>here is what i have so far, i apologies if its messy</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; #include &lt;ctype.h&gt; //int getNumber (aNumber) { // printf("Enter an integer between 0 and 1000.\n"); // scanf("%i", &amp;aNumber); // int result; // } char getMenuLetter(); int getNumber(); //declare variables int aNumber = 0; float avg = 0.0; int high = -1; int low = 1001; int total = 0; int count = 0; char getChoice = 'x'; int main() { //proptotype functions do { getChoice = getMenuLetter(); switch (getChoice) case 'A': aNumber = getNumber(); count++; total += aNumber; low = testLow(aNumber, low) high = testHigh(aNumber, high); break; case 'B'; avg = (double) total/count; //display avg printf("The average is %.2f", avg); break; case 'C': high = getHigh(); printf("The highest value of all the numbers entered is %i.\n", high); //display highest number break; case 'D': low = getLow; printf("The lowest value of all the numbers entered is %i.\n", low); //displayer lowest value break; case 'E': printf("The total of all the numbers entered is %i.\n", total); break; case 'F': printf("The amount of numbers entered so far is %i.\n", count); case 'G'; break: //end switch } while (userChoice != 'G'); } int testLow(int n) { int result; if (n &lt; low) result = n; else return 0; } //End of main char getMenuLetter() { char result; system("cls") //clear the screen. printf("*************************************************\n"); printf("A) Enter a number between 0 and 1,000\n"); printf("B) Display the average\n"); printf("C) Display the highest value entered\n"); printf("D) Display the lowest value entered\n"); printf("E) Display the sum of all numbers\n"); printf("F) Display the count of all numbers entered\n"); printf("G) Quit the program\n"); printf("*************************************************\n"); scanf("%c", &amp;result); result =toupper(result); ///print f %c //system pause if (result != 'A' || result != 'B' || result !='C' || result !='D' || result !='E' || result != 'F' || result !='G'){ printf("You must enter A - G only! \n)"); system("pause"); } //end if } while(result != 'A' || result != 'B' || result !='C' || result !='D' || result !='E' || result != 'F' || result !='G'); return result; //end of GetMenuLetter </code></pre>

    1. COHave you tried compiling this yet? If so, you'd see where your problems are. There are tons. I'd start there, try to work out as many errors as possible, then ask for help where you're terribly stuck.

    2. COin testLow function: it should if(n < low) return n; else return low; and if you are going to use the global variable low in it, then you can remove the argument L. First thing I see.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
