Description:

The topic of this programming assignment is the same as Lab #2: determining the gold-medal winner of a halfpipe snowboarding competition, based on scores that are examples of actual data compiled and analyzed during the recent winter Olympic Games in South Korea. In this lab, you will be reusing and making minor modifications in the code you wrote for Lab #2.New requirement for this lab: The names of all snowboarders and scores earned for one run should be saved in a data file, rather than entered on the keyboard.

Instructions: Using the example programs provided on Blackboard in the folder named Lab3, add the necessary code to your program from Lab #2 in order to read the data for each snowboarder from a data file rather than the keyboard.

(Example 1) #include  // Lab 3 example int main() { /* Declare variables */ char firstnames [3][15]; char lastnames [3][20]; int scores [6]; int i,j; int sum; float average; FILE *fp; // define pointer variable of type FILE /* Open data file associated with fp in read mode */ fp=fopen("data.txt", "r"); /* Check if open was successful */ if (fp == NULL) // Not successful { printf("Program cannot open the file "); return -1; // indicates a problem; if you have this, // no need for else below } else // strictly speaking not required, but helps mark place { for (i=0; i<3; i++) // This requires trusting there are 3 entries { /* Prompt and read in values */ printf("Enter fn ln and 6 scores. "); fscanf(fp,"%s %s ",&firstnames[i],&lastnames[i]); /* Echo print name */ printf("The name is: %s %s ",firstnames[i],lastnames[i]); sum = 0; /* Read in 6 scores */ for (j=0; j < 6; j++) { fscanf(fp,"%d", &scores[j]); /* Echo print each score read */ printf("The score is: %d ",scores[j]); sum = sum + scores[j]; } printf("The sum for this snowboarder is: %d ",sum); /* Find average of ALL 6 scores */ average = float(sum) / 6; printf("The average for this snowboarder is: %f ",average); } //end of for loop using i fclose(fp); } // end of else } //end of main

Use the provided file data.txt as the sample test case. This file has data for 4 snowboarders, in the same format as used for Lab #2.

There will be three versions of your Lab #3, as described below. All three will use data from the input data file.

In the first version, keep your for-loop to read and process the data for each of the snowboarders, but read the data from the input data file rather than the keyboard. Test your program and capture a screenshot of the output. It should show that there is processing for only 3 snowboarders, despite the fact that the data file has data for 4. Insert your screenshot into the Testing--Screenshot of output window section in your Lab Report. Below the screenshot, explain the output results.

Second, revise your program (you can just comment out lines not needed and add new ones) so that it uses a while-loop to control the processing for each snowboarder rather than a for-loop. Refer to the example program provided, Version 2. There is just one while-loop to be added; do not replace internal for-loops that handle other tasks. Test your program and capture a screenshot of the result. Place the screenshot in your lab report and explain the output results.

Finally, revise your program again so that it uses a compound test for your while-loop, as shown in the example program, Version 3. This while loop checks if there is additional data left to read AND checks that there will not be an attempt to over-fill the array. Test your program and capture a screenshot of the result. Place the screenshot in your lab report and explain the output results.
