Need assistance with C code, not running

Question

#include <stdio.h>

struct students{ //struct student

char FirstName; //String to store first name

char secondName; //string to store second name

int ID; //student ID

float GPA; //student gpa

char Progression; //Studnet progression status

};

int main()

{

struct students sp[10] ;

FILE *fp;

fp = fopen("YearOneICT.txt", "r");

if (fp == NULL)

{

printf("File not found");

return 0;

}

int students[10]; // array to h

int i = 0;

while (fscanf(fp, "%s %s %d %f", &sp[i].FirstName, &sp[i].secondName, &sp[i].ID, &sp[i].GPA) != EOF)

else

if(sp[i].GPA>=2.0 && sp[i].GPA<=3.8) sp[i].Progression = 'N'; sp[i] = 0;}

else {sp[i].Progression = 'P'; sp[i] = -1;}

FILE *fp1;

if (fp1 == NULL)

The data for YearOneICT.txt is as follows:

Alan Bob 13176 3.65

Brad Chance 11198 1.71

Chelsea Donald 39528 2.14

David Edwards 22469 3.88

Elenor Franks 44938 3.46

Fred Guess 11246 3.50

Gavin Hill 79056 1.20

Helen Indar 69360 3.20

Ian James 44888 2.58

Jenny Kahn 34168 1.83

The program aims to capture the data from the text file and generate an output file with the format:

ClassSummary.txt

Honours List:

David Edwards 22469 3.88

Progressing Normally:

Alan Bob 13176 3.65

Chelsea Donald 39528 2.14 …

Academic Probation:

Brad Chance 11198 1.71 …

Hi Amelia,

Here is the part of your code which has syntax errors:

sp[i].Progression = 'H';

sp[i] = 1; // ERR: cannot set sp[i] equal to an int, check members of sp

} //Decide studens progression depeding on their GPA

else if(sp[i].GPA>=2.0 && sp[i].GPA<=3.8) // ERR: forgot open {

sp[i].Progression = 'N';

sp[i] = 0; // ERR: cannot set sp[i] equal to an int, check members of sp

}

else {

sp[i].Progression = 'P';

sp[i] = -1;

}

fp1 = fopen("ClassSummary.txt", "w");

if (fp1 == NULL)

{

printf("File not found");

return 0;

}

fprintf(fp1,"Honours List\n");

for(int i =0;i<10;i++){

if(sp[i].Progression=='H'){

fprintf(fp1, "%s %s %d %f", sp[i].FirstName, sp[i].secondName, sp[i].ID, sp[i].GPA));// ERR: extra )

printf("%s %s %d %f", sp[i].FirstName, sp[i].secondName, sp[i].ID, sp[i].GPA);

}

}

fprintf(fp1,"Progessing Normally\n");

for(int i =0;i<10;i++){

if(sp[i] == 'N'){ // ERR: cannot set sp[i] equal to a char, check members of sp

fprintf(fp1, "%s %s %d %f", sp[i].FirstName, sp[i].secondName, sp[i].ID, sp[i].GPA)); // ERR: extra )

printf("%s %s %d %f", sp[i].FirstName, sp[i].secondName, sp[i].ID, sp[i].GPA);

If you compile this code, you should see these errors too, either in your IDE or at the command line, depending on how you are compiling. I made comments in the code showing you what is wrong. These are syntax errors. Once the syntax errors are handled, then you can run the code and see if your logic works.

I hope this helps.
