Thread: Doubt about max, minimum and average value with if function

Hi,
I started this semester with C programming and one of the assignments asks to find the max value, minimum value and average of 10 integers with range of 0 and 100.

So here is what I did:

Code:

int grad0,grad1,grad2,grad3,grad4,grad5,grad6,grad7,grad8,grad9;

	if (grad0 > grad1 && grad0 > grad2 && grad0 > grad3 && grad0 > grad4 && grad0 > grad5 && grad0 > grad6 && grad0 > grad7 && grad0 > grad8 && grad0 > grad9)
			{
				printf("The max value of your grades is: %d\n", grad0);
			}
		else if (grad1 > grad0 && grad1 > grad2 && grad1 > grad3 && grad1 > grad4 && grad1 > grad5 && grad1 > grad6 && grad1 > grad7 && grad1 > grad8 && grad1 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad1);
		}
		else if (grad2 > grad0 && grad2 > grad1 && grad2 > grad3 && grad2 > grad4 && grad2 > grad5 && grad2 > grad6 && grad2 > grad7 && grad2 > grad8 && grad2 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad2);
		}
		else if (grad3 > grad0 && grad3 > grad1 && grad3 > grad2 && grad3 > grad4 && grad3 > grad5 && grad3 > grad6 && grad3 > grad7 && grad3 > grad8 && grad3 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad3);
		}
		else if (grad4 > grad0 && grad4 > grad1 && grad4 > grad2 && grad4 > grad3 && grad4 > grad5 && grad4 > grad6 && grad4 > grad7 && grad4 > grad8 && grad4 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad4);
		}
		else if (grad5 > grad0 && grad5 > grad1 && grad5 > grad2 && grad5 > grad3 && grad5 > grad4 && grad5 > grad6 && grad5 > grad7 && grad5 > grad8 && grad5 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad5);
		}
		else if (grad6 > grad0 && grad6 > grad1 && grad6 > grad2 && grad6 > grad3 && grad6 > grad4 && grad6 > grad5 && grad6 > grad7 && grad6 > grad8 && grad6 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad6);
		}
		else if (grad7 > grad0 && grad7 > grad1 && grad7 > grad2 && grad7 > grad3 && grad7 > grad4 && grad7 > grad5 && grad7 > grad6 && grad7 > grad8 && grad7 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad7);
		}
		else if (grad8 > grad0 && grad8 > grad1 && grad8 > grad2 && grad8 > grad3 && grad8 > grad4 && grad8 > grad5 && grad8 > grad6 && grad8 > grad7 && grad8 > grad9)
		{
			printf("The max value of your grades is: %d\n", grad8);
		}
		else if (grad9 > grad0 && grad9 > grad1 && grad9 > grad2 && grad9 > grad3 && grad9 > grad4 && grad9 > grad5 && grad9 > grad6 && grad9 > grad7 && grad9 > grad8)
		{
			printf("The max value of your grades is: %d\n", grad9);
		}
	if (grad0 < grad1 && grad0 < grad2 && grad0 < grad3 && grad0 < grad4 && grad0 < grad5 && grad0 < grad6 && grad0 < grad7 && grad0 < grad8 && grad0 < grad9)
			{
				printf("The min value of your grades is: %d\n", grad0);
			}
		else if (grad1 < grad0 && grad1 < grad2 && grad1 < grad3 && grad1 < grad4 && grad1 < grad5 && grad1 < grad6 && grad1 < grad7 && grad1 < grad8 && grad1 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad1);
		}
		else if (grad2 < grad0 && grad2 < grad1 && grad2 < grad3 && grad2 < grad4 && grad2 < grad5 && grad2 < grad6 && grad2 < grad7 && grad2 < grad8 && grad2 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad2);
		}
		else if (grad3 < grad0 && grad3 < grad1 && grad3 < grad2 && grad3 < grad4 && grad3 < grad5 && grad3 < grad6 && grad3 < grad7 && grad3 < grad8 && grad3 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad3);
		}
		else if (grad4 < grad0 && grad4 < grad1 && grad4 < grad2 && grad4 < grad3 && grad4 < grad5 && grad4 < grad6 && grad4 < grad7 && grad4 < grad8 && grad4 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad4);
		}
		else if (grad5 < grad0 && grad5 < grad1 && grad5 < grad2 && grad5 < grad3 && grad5 < grad4 && grad5 < grad6 && grad5 < grad7 && grad5 < grad8 && grad5 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad5);
		}
		else if (grad6 < grad0 && grad6 < grad1 && grad6 < grad2 && grad6 < grad3 && grad6 < grad4 && grad6 < grad5 && grad6 < grad7 && grad6 < grad8 && grad6 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad6);
		}
		else if (grad7 < grad0 && grad7 < grad1 && grad7 < grad2 && grad7 < grad3 && grad7 < grad4 && grad7 < grad5 && grad7 < grad6 && grad7 < grad8 && grad7 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad7);
		}
		else if (grad8 < grad0 && grad8 < grad1 && grad8 < grad2 && grad8 < grad3 && grad8 < grad4 && grad8 < grad5 && grad8 < grad6 && grad8 < grad7 && grad8 < grad9)
		{
			printf("The min value of your grades is: %d\n", grad8);
		}
		else if(grad9 < grad0 && grad9 < grad1 && grad9 < grad2 && grad9 < grad3 && grad9 < grad4 && grad9 < grad5 && grad9 < grad6 && grad9 < grad7 && grad9 < grad8)
		{
			printf("The min value of your grades is: %d\n", grad9);
		}
int aver = (grad0+grad1+grad2+grad3+grad4+grad5+grad6+grad7+grad8+grad9)/10;
	printf("The average of your grades is: %d\n",aver);

Imagine that the integers have already a value by doing a scanf.

My problem starts when two or more integers have the same value, the minimum and/or maximum value will not appear.

How can I solve this problem?

Thanks for your help and happy Programming!
