It seems as though I've written the code perfectly, although its not executing properly. I have to read a bunch of data from a file (which i named test.txt) and then execute a bunch of options to the user via a menu. heres the code.

Code:#include <stdio.h> int main(void) { //initialize variables char fname[128]; int size = 0; FILE* fin; int count = 0; int option; int low_bound; int high_bound; int x; double average = 0; int lowest = -1; int highest = 0; int target_donation; int target_count = 0; int target_donation2; int target_count2 = 0; int target_donation3; double percentage; int sum = 0; int total_under; int number[size]; //Prompts user for the name of their data file to read. printf("Please enter the name of the data file\n"); scanf("%s", fname); //Notice the "r". If it were a "w" it would be writing, not reading to the file fin = fopen(fname, "r"); //This line scans the file that it is reading, and is reading the numbers within the file fscanf("%d ",&size); //This while loop accumulates the number of numbers within the file. while(!feof(fin)) { fscanf(fin,"%d ", &number[count]); count++; } //Close the file fclose(fin); //Tells the user how many numbers were read within the file printf("The data for %d numbers of contributions has been read.\n", count); while(1==1) { //Now starts the menu process, asking the user for his/her choice printf("Please make a choice from the following options:\n"); //Full menu printf("1. Calculate the average donation for a subset of the donations.\n"); printf("2. Calculate the minimum donation for a subset of the donations.\n"); printf("3. Calculate the maximum donation for a subset of the donations.\n"); printf("4. Calculate the number of donations exceeding a target value.\n"); printf("5. Calculate the number of donations of a particular dollar amount.\n"); printf("6. Calculate what percentage of the donations (Value Wise) are under a target value.\n"); printf("7. Quit\n"); //Scanning the users option for the menu list scanf("%d", &option); //If the user chooses to quit, they will type 7, which the computer will read and return the program to quit if(option == 7) { system("PAUSE"); return 0; } //I grouped options 1 to 3 because they all use the lower and higher bound variables. //I was going to individually write each option out, but grouping the 3 was easier. if((option >= 1)&&(option<=3)) { printf("What is the low bound for your group(0-%d)?\n", size); scanf("%d", &low_bound); printf("What is the high bound for your group(0-%d)?\n", size); scanf("%d", &high_bound); if(option==1) { for(x=low_bound; x<=high_bound; x++) { average+=number[x]; } average=average/size; printf("The average donation from person %d to person %d is $%.2lf.\n", low_bound, high_bound, average); } if(option==2) { for(x=low_bound; x<=high_bound; x++) { if(number[x]<lowest) { lowest=number[x]; } } printf("The smallest donation from person %d to person %d is $&d .\n", low_bound, high_bound, lowest); } if(option==3) { for(x=low_bound; x<=high_bound; x++) { if(number[x]>highest) { highest=number[x]; } } printf("The largest donation from person %d to person %d is $%d .\n", low_bound, high_bound, highest); } } //Now to compute if the user selects option 4 //This time around, I chose to split up the 3 options that use the common variable of a target donation if(option==4) { printf("What is the target donation?\n"); scanf("%d", &target_donation); for(x=lowest; x<highest; x++) { if(target_donation>=number[x]) //consider revising { target_count++; } } printf("%d people donated more than %d .", target_count, target_donation); } //Now to compute if the user selects option 5 if(option==5) { printf("What is the target donation?\n"); scanf("%d", &target_donation2); for(x=lowest; x<=highest; x++) { if(number[x]==target_donation2) //consider revising { target_count2++; } } printf("%d people donated exactly $%d .\n", target_count2, target_donation2); } //Now to compute if the user selects option 6 if(option==6) { printf("What is the target donation?\n"); scanf("%d", &target_donation3); for(x = 0; x < count; x++) { sum += number[x]; } for(x=lowest; x<=highest; x++) { if(total_under < target_donation3) { total_under+= number[x]; } } percentage = (sum/total_under) * 100; printf("Donations under $%d accounted for %.2lf percent of the funds raised",target_donation3, percentage); } } system("PAUSE"); return 0; }

So test.txt is a file with this written in it:

10

50

25

75

2000

30

500

800

10

25

485

where the output should be similar to this:

Can anyone help me as to why the file isn't executing properly? Thanks in advance.Please enter the name of the data file.
