    Parse Error - Anyone Help?

    Hi guys,

    I have a parse error, it maybe syntax or just some code is not right. Anybody help?

    Here is the code:

    [tag]

    Code:
    #include <stdio.h>
    #include <ctype.h>
    
    struct student
    
    {
    char* list[50];
    char* number[10];
    char* name[20];
    char* grade[20];
    };
    
    struct student list [10]={
    {"000001", "Bloomer", "B"},
    {"000002", "Brown", "A"},
    {"000003", "Carter", "A"},
    {"000004", "James", "B"},
    };
    
    char GetOption()
    {char option = 'I';
    while(option == 'I'){
    {printf("\n");
    printf(" Please choose one of the options: \n \t\t\t [U]pdate  [P]rint [S]earch  [E]xit \n");
    scanf("%c", &option);
    switch (toupper(option))
    {
    case 'U' :
    case 'P' :
    case 'S' :
    case 'E' :
    break;
    default:
    option = 'I';
    break;
    }
    }
    
    void searchstudent()
    { int count;
    char num,f;
    printf("Enter the student number you wish to search for : \n");
    scanf("%c", &num);
    f='b';
    for (count=0; count<10; count++)
    {
    if(num==struct student list [count])
    {
    print("%c was found at location %d", num, count);
    count=10;
    f='a'
    }
    }
    if (f=='b') printf("%c was not found", id);
    }
    [/tag]



    'Parse error before struct'


    This is not the whole code but just trying to break the code down.

    Thanks

    There are 2 closing brackets missing ! Indent your code
    Code:
    char GetOption()
    {
    	char option = 'I';
    	while(option == 'I')
    	{
    		{
    			printf("\n");
    			printf(" Please choose one of the options: \n \t\t\t [u]pdate  [P]rint
    					[S]earch  [E]xit				
    					\n");
    			scanf("%c", &option);
    			switch (toupper(option))
    			{
    				case 'U' :
    				case 'P' :
    				case 'S' :
    				case 'E' :
    					break;
    				default:
    					option = 'I';
    					break;
    			}
    		}

    Thanks, I can now see that and have amended, however still same problem

    Seems to be in this area of code / function:

    [tag]
    Code:
    void searchstudent()
    { int count;
    char num,f;
    printf("Enter the student number you wish to search for : \n");
    scanf("%c", &num);
    f='b';
    for (count=0; count<10; count++)
    {
    if(num==struct student list [count])
    {
    print("%c was found at location %d", num, count);
    count=10;
    f='a'
    }
    }
    if (f=='b') printf("%c was not found", id);
    }
    [/tag]

    }
    if (f=='b') printf("%c was not found", id);
    }
    ; is missing here !

    You could have done this bracketing and semi colon exercise yourself too !

    Parse error before, before STRUCT:

    line 52 if(num== struct student list [count])


    I am doing something wrong in this line compared to the original code:

    the f='a' is after this bit of code..



    'parse error before struct, line 52'

    Whenever you reference the structure after you have declared it, you do not need to write 'struct student', just 'list' (and the element number).

    Also, you're attempting to compare a character to a structure, this cannot be done with relational operators like ==. If you want to compare it to a member of the structure you have to use the dot operator.

    This mistake isn't really obvious even with good indentation but as AnishaKaul has stated, indentation is very helpful and pretty much a requirement if you wish for other people to read your code. Next time you post, please indent your code.

    OK, here is my problem stripped down...

    If anyone could help then it would be great..

    These are my structures:


    [tag]
    Code:
    
    struct student
    {
    
    char* number[10];
    char* name[20];
    char* grade[20];
    };
    
    struct student records[4]={
    {"00001", "Bloomer", "B"},
    {"00002", "Smith", "A"},
    {"00003", "James", "B"},
    {"00004", "Doug", "C"},
    };
    [/tag]

    That bit looks OK, and you can see the labels that I have used:


    My function when I am trying to call the labels are for example, when trying to load them:


    [tag]
    Code:
    void Loadstudents (struct student records[])
    {
    FILE *fp=fopen("records.txt", "r");
    }
    [/tag]



    The void 'Loadstudents (struct student records[])' part, I am not sure about.

    Thanks

    OK not sure why it is reposting my messages, checked all settings and seem fine?

    Anyway I have worked quite a bit on my code overnight and have got 90% of it working, just wanted to ask some help on data being stored in a file and then retrieved.

    These are my two functions for adding a record, and listing records:


    [tag]
    Code:
     void Add(void){
    char opt;
    fp=fopen("Records2.txt","a");
    printf("\nAdd Record");
    printf("\nStudent Name:"); scanf(" "); gets(record.Name);
    printf("\nStudent Number:");scanf(" "); gets(record.Number);
    printf("\nStudent Grade:");scanf(" "); gets(record.Grade);
    fprintf(fp,"%s %s %s ",record.Name,record.Number,record.Grade);
    printf("Press any key to go to main menu..."); 
    getch();
    fclose(fp);
    }
    [tag]


    [tag]
    Code:
    void List(void){
    int count=0,i, x=0;
    fp=fopen("Records2.txt","r");
    printf("Name   Number   Grade\n\n");
    for(i=1;i<1;i++){ ;puts("");}
    while(fscanf(fp,"%s %s %s",&record.Name,&record.Number,&record.Grade)!=EOF){
    if(count!=0&&count%5==0){ printf("Press any key to continue..."); getch(); x=0;
    for(i=10;i<=24;i++);}
    }
    printf("%s   %s    %s",record.Name,record.Number,record.Grade);
    x++;
    count++;
    printf("\nPress any key to go to main menu...");
    getch();
    fclose(fp);
    }
    [/tag]


    These all compile and work to a degree but when I run my program, only the last record is shown on the screen and not all the records stored in the text file. Any hints or help on this?

    I do not think I am a million miles away..

    Thanks In Advance!
