Thread: How can I display a print function x amount of times?

Hey, im new to C and i'd like to know how I can display the information stored in an array.

How can the code work so that if only 3 slots (for example) in the array are stored with information, the info stored in a[4], and a[5] will not print.

I'm aware of the concepts of for loops, however I cant seem to figure out how to limit how many messages are displayed depending on how many slots in the array contain user stored information (as mentioned above).

Code:

                     

printf("           %d-%d-%d  %lf\n", a[1].day, a[1].month, a[1].year, a[1].GPA);                    
printf("           %d-%d-%d  %lf\n", a[2].day, a[2].month, a[2].year, a[2].GPA);
printf("           %d-%d-%d  %lf\n", a[3].day, a[3].month, a[3].year, a[3].GPA);                    
printf("           %d-%d-%d  %lf\n", a[4].day, a[4].month, a[4].year, a[4].GPA);                    
printf("           %d-%d-%d  %lf\n", a[5].day, a[5].month, a[5].year, a[5].GPA);

Thanks

Or maybe

Code:

int i = 1; // 1 because that’s the first number listed in your example code
while( a[i] ) {
	printf("           %d-%d-%d  %lf\n", a[i].day, a[i].month, a[i].year, a[i].GPA);
	i++;
}
