problems with printing to a txt file from array

[joshdonaldson]

just having a few issues here in printing multiple lines to a txt file.
basically my lotto program searches and matches the same numbers between two arrays however when there is more than one match its only prints 1 line, not all of them.

any help or suggestions would be much appreciated

insert

int main(void)
{


FILE *fpointer;
fpointer = fopen("bacon.txt", "w");


    int a;
    int i;
    int j;
    int x;
    int y;
    int selection[6];
    int lotto[6];
    int match[6];
    char answer;
    x=0;
    y=0;
    i=0;
    a=0;


        printf("Hello and Welcome to Donaldson's Super Duper Lottery! \n \n");
        printf("Please enter your 6 lucky numbers between 1 and 22: \n \n");
        printf("Enter selected NUMBER then hit return to enter next number below \n \n");
        printf(" \n");


        for(i=0 ; i<6; i++)
            {
            scanf("%d", &selection[i]);
            }
            printf("\n  Your Lucky Numbers for tonights game: \n");
            for (i=0;  i<6;  i++){
            printf("%5d", selection[i]);
            }


        printf("\n\n\n Ready to Draw???? PRESS 1 then RETURN TO REVEAL!  \n");
        scanf("%d", &answer);


        if (answer == 1){
            printf(" \n\n Tonights Lucky Draw Numbers are: \n");
            srand(time(NULL));


            for(j=0 ; j<6  ;j++){
            lotto[j] = rand()%6+1;
            printf("%5d", lotto[j]);
}}


printf("\n \n \n  Ready to see if your matching numbers???   PRESS 1 then RETURN TO REVEAL! \n");
scanf("%d", &answer);
    if (answer == 1){
for (x=0;x<6;x++){
    for(y=0;y<6;y++){
        if(selection[x]== lotto[y])
        {match[a] = selection[x];
            printf("\n Number %d is a WINNER!", match[a]);
            fprintf(fpointer,"Number %d is a WINNER! \n", match[a]);


fclose(fpointer);
}}}
if(match [a]==0)
printf("\n You have no winning numbers...YOU LOSE! \n \n \n");
return(0);

A few things to work on first:

• Indent your code properly. This means picking a set number of spaces or a single tab per indent level, and sticking to it. You seem to have picked 4 spaces, so be consistent. Your indent style should also be consistent: if you want the opening brace to be on its own line, then always do it like that. Closing braces should generally be on their own lines.
• Remember to include the required headers.
• Make your variable names descriptive: avoid single letter variable names except for loop indices. So your i and j are fine, but I'm not sure why you need a, and why not reuse i and j instead of also having x and y.
• Use named constants instead of magic numbers like 6.
• You might as well initialise variables in the declaration instead of declaring them then assigning initial values separately.
• Check the return value of fopen and scanf.
• Break up your code into smaller functions that each do one thing and do it well.
• It's probably better to move the srand call to near the top of the main function so you eliminate the risk of calling it more than once with the same seed.

Your indentation is bad and you should feel bad... I'm joking, but you should pay more attention to the readability of your code.

About your problem, of course it prints only one line, since you close the file right after you write to it. I bet this error was directly caused by your awful indentation.

thanks for that. will tidy it up.

any suggestions to make my text file read for example;
1 is a WINNER
2 is a WINNER

etc
