    outputting an array

    Code:
    void printoutput(const float prices[], const char taxable[], const int lines)	
    {
    	int i;
    
    
    	puts("Price Taxable");
    	puts("----- -------");
    
    
    	for(i = 0; i<=lines; i++){
    	printf("%2.2f%5c\n",prices[i],taxable[i]);
    	}
    
    
    }
    if lines is equal to 6, then its going to print out 7 elements (the last one being garbage value). I know I can do for(i = 0; i<=(lines-1); i++) but is there an alternative?

    The typical pattern is:
    Code:
    for (i = 0; i < lines; i++)

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
