Question

In this program I have a file called ‘accounts.dat’ and in this file there are some lines of data like

1000:first
2000:second
3000:third

But when I tried to fscanf the data values into my arrays in my program I get:

0:$ s·°Ïÿ¿
1:t·¨BuÞZ·
-1217025816:s·0s·É¥s·hp[·4£s·

As the values scanned, or at least thats what it’s showing.

My function to scan the values is:

void read (int accounts[MAX], char debcred[MAX], double amount[MAX], char accname[][MAXSTRING], char transname[][MAXSTRING], int *i) {

FILE *fp1 = NULL;
//FILE *fp2 = NULL;

fp1 = fopen("accounts.dat", "r");
//fp2 = fopen("transactions.dat", "r");

int h = 0;



if (fp1 != NULL) // READING THE FILE
{
    while(fscanf(fp1, "%d", &accounts[h]) != EOF)
    {

            fgetc(fp1);
            fscanf(fp1, "%30[^\n]", &accname[h]);
            h++;

            printf("%d:%s\n", accounts[h], accname[h]);

    }

    fclose(fp1);
}
else
    printf ("Failed to open file\n");

}

And how I call my read function in my main is:

read(accounts, debcred, amount, accname, transname, &i);

And my declarations in my main function is:

int accounts[MAX], accounts2[MAX], account;
char debcred[MAX], accname[MAX][MAXSTRING], transname[MAX][MAXSTRING];
double amount[MAX];

Can anyone figure out what my problem is? Why aren’t the data lines in my file being scanned into my arrays in my program properly?

Answer 1

fscanf(fp1, "%30[^\n]", &accname[h]);
h++;
printf("%d:%s\n", accounts[h], accname[h]);

Try incrementing h after you print.
