Thread: Array issue?

In working on a homework assignment and pretty much have it completed. However, I am having an issue with my first entry every time i use the program. It always gives me a large number for OT and the rest of the outputs are correct. Any thoughts, thanks.

Code:

#include <stdio.h>


#define STD_HOURS 40.0
#define OT_HALF 2.0
//#define NUM_EMP 5.0


int main (void)
{
	
/*	Declare Variables	*/
	int NUM_EMP = 5;
	int i = 0;				//Accumulator for Loop;
	int a = 0;				//Accumulator for Arrays;
	int clock_num[4];		//Employee Clock Number;
	float emp_hours[4];		//Employee Hours;
	float emp_wage[4];		//Employee Wage Rate;
	float emp_gross[4];		//Employee Total Gross;
	float emp_otime[4];		//Employee Over Time;
	float ot_acc[4];		//Accumulator for OT;
	float ot_wage[4];		//Accumulator for OT Wage;


/*	Main Program	*/
	
	printf("***Gross Pay Calculator***\n");
	printf("\n");




/*	Begin Employee Input */	


	for (i = 0; i < NUM_EMP; i++)
	{
		for (a = 0; a < NUM_EMP; a++)
		{
		printf("Enter Employee's Clock #:\n");
		scanf("%i", &clock_num[a]);
		printf("Enter hourly wage:\n");
		scanf("%f", &emp_wage[a]);
		printf("Enter number of hours worked:\n");
		scanf("%f", &emp_hours[a]);
		printf("\n");
			if (emp_hours[a] > STD_HOURS)
			{
			ot_wage[a] = emp_wage[a];
			ot_wage[a] = ((ot_wage[a] / OT_HALF) + emp_wage[a]);
			ot_acc[a] = emp_hours[a] - STD_HOURS;
			emp_otime[a] = ot_acc[a] * ot_wage[a];
			}
		emp_gross[a] = emp_wage[a] * emp_hours[a] + emp_otime[a];
		}
	
/*	Display Results	*/


	printf("-----------------------------------------\n");
	printf("Clock #	Wage	Hours	OT	Gross\n");
	printf("-----------------------------------------\n");
		
		for (a = 0; a < NUM_EMP; a++)
		{
		printf("%06i	%5.2f	%5.1f	%.1f	%.2f\n", clock_num[a], emp_wage[a], emp_hours[a], ot_acc[a], emp_gross[a]);
		printf("\n");
		}
	}
}

One of your problems is that your accessing your arrays out of bounds. You created your arrays with a size of 4 yet you loop 5 times.
