Thread: Help!!! Assignment due tomorrow

I need help for an assignment due tom! I did 7 all i need to do is these three more but im too tired HAHA.

1. Write a program that determines the combinations of x, y, and z with each value ranging from -500to +500 that would make the following expression true: 2x – 3y >= 5z

2. Write a program that will take in a non-negative integer. If the non-negative integer is a primenumber, ask for another number n. Then, generate the next n prime numbers after the given primenumber. If the number is not prime, just indicate “Not Prime”. For example, if input non-negativenumber is 7 and n is 4, then the program should display: 11 13 17 19

3. Write a program that will display the following pattern given n, where n represents the number oflines and the width of the pattern to be generated. Assume that n will be a positive odd integer thatwill at least be 3. Your program should follow the skeleton below:

I did the first one

Code:

#include <stdio.h>
int main()
{
	int x,
		y,
		z;
for(z=-500; z<=500;z++)	
{
	for(y=-500;y<=500;y++)
	{
		for(x=-500; x<=500; x++)
		{
			if(2*x - 3*y >= 5*z)
			{
				printf("x = %d ,y = %d, z = %d\n",x,y,z);
			}
		}
	}	
}
return 0;
}

but im still having a hard time on the 2nd and 3rd

What exactly are the problems you are having with the other ones?
