Controlling Repetition in a Structure
Hey all, having a bit of a problem with controlling the repetition of input into a structure.
It seems that if i use a while loop with an integer as its condition then it will work fine, but if i want the while condition to be with a string, or char, then it seems to stay in the loop and i can't get out.
Anyway i've posted the code, so if anyone can help me it would be great.
Code:
#include <stdio.h>
#define MAX_STUDENT 10 /* size of structure array */
typedef struct {
int studentNum;
char lastName[ 15 ];
char firstName[ 10 ];
double balance;
} studentData;
void read_studentRecord( studentData [] );
void print_studentRecord( studentData []);
int main()
{
studentData student[MAX_STUDENT]; /* define a structure array of size MAX_CLIENT */
read_studentRecord( student );
print_studentRecord( student );
return 0;
}
/* Read client records and store them in a structure */
void read_studentRecord( studentData student[] )
{
int i = 0;
printf( "Enter student number( E.g S00023456, (0 to end input) )\n? " );
scanf( "%d", &student[i].studentNum );
while ( student[i].studentNum != 0 )
{
printf( "Enter lastname, firstname, Phone #\n? " );
scanf( "%s%s%lf",student[i].lastName, student[i].firstName,
&student[i].balance );
i++;
printf( "Enter account number\n? " );
scanf( "%d", &student[i].studentNum );
}
}
/* Print client records stored in the structure */
void print_studentRecord( studentData student[] )
{
int i = 0;
if (student[0].studentNum != 0)
printf( "\n%-6s%-16s%-11s%10s\n\n", "Acct", "Last Name",
"First Name", "Balance" );
while ( student[i].studentNum != 0 )
{
printf( "%-6d%-16s%-11s%10.2f\n", student[i].studentNum,
student[i].lastName, student[i].firstName, student[i].balance );
i++;
}
}
Thanks again
